Top 100 Latest Research Topics in Molecular Biology 2024 [Updated]

Table of Contents

Introduction

Molecular Biology is a branch of biology that deals with the composition, structure, and communications of cellular molecules like proteins and nucleic acids responsible for various biological procedures for maintaining and functioning cells. It mainly involves multiple biomolecules such as amino acids, lipids, proteins, nucleic acids, and carbohydrates, along with their structure, compositions, and interactions in the life processes. A molecular biologist is responsible for doing experiments to investigate structures, functions, processing, and regulation of biological molecules and their interactions. A molecular biologist also tries to understand a molecule’s structure, which includes details like shape and the location of the active sites on a protein, impacting the function of a molecule. Such information offers basic knowledge on how biology functions and assists in informing the efforts of various scientists looking to manipulate that biology. Such scientists involve drug designers and also genetic engineers.

Now-a-days a lot of research is going on in molecular biology and people are in search of novel areas in molecular biology for conducting research with a sole purpose of finding some new techniques or new things that can be used for human or animal welfare. Students of graduation, post-graduation and PhD levels are working on several topics for their research work. Let’s have a look on some of the trending topics in molecular biology for doing research.

How molecular biology affects life science?

Molecular biology has a significant effect on investigations in life science. Some major molecular biology advancements encouraged research and progressions in every life science discipline. Some of the advancements are

• Development of various experimental methods in molecular biology with wide applications
• The increasing flow of data on various technical novelties and scientific discoveries all over the scientific community
• Development of specified software and consistently updated database for analysis and storage of data on the genotypes.
• All this has resulted in revolutionizing discoveries in various sectors of molecular biology. One of the best examples is the invention of high throughput biology, high-level sequencing, and Recombinant DNA technology that assisted in unveiling the high complicacies of the genome and explicating the precise methods for transmitting genetic information.

With this rapidly changing and consistently evolving nature of the molecular biology sector, it can be easily anticipated that the innovatory effect of Molecular biology in life science is just beginning and is far from being finished.

In recent decades, advances in methods in molecular biology and genetics have revolutionized multiple areas of the life and health sciences. However, there remains a global need for the development of more refined and effective methods across these fields of research. In this current Collection, we aim to showcase articles presenting novel molecular biology and genetics techniques developed by scientists from around the world.

A brief overview of the development of methods of molecular biology and genetics

Since ancient times, humankind has recognized the influence of heredity, based on familial resemblance, selective breeding of livestock, and climate-adapted crops. Prior to Gregor Johann Mendel’s work in the nineteenth century, there was no clear scientific theory to explain heredity. Mendel’s work remained essentially theoretical until the discovery of DNA and confirmation of its role as the principal agent of heredity in organisms in the twentieth century [ 1 ]. In addition, the resolution of the DNA structure paved the way for the invention of the Polymerase Chain Reaction (PCR) (by Kary Mullis), nucleotide synthesis [ 2 ] and the Sanger sequencing method [ 3 ] which revolutionized the field of genetics and led to the development of several sub-disciplines, including cytogenetics, biotechnology, bioprocess technology, and molecular biology. Automation of Sanger sequencing led to the Human Genome Project in 1990 [ 1 ], soon followed by sequencing the complete genomes of numerous other species of flora and fauna [ 4 ].

In recent decades, advances in methods in molecular biology and genetics have revolutionized multiple areas of life and health sciences [ 2 ]. As a major example from health sciences, PCR-based methods have advanced our understanding of the aetiology of a myriad of acute and chronic diseases, in addition to allowing the diagnosis of multiple disorders [ 1 , 5 ]. As a recent global application of molecular methods, the PCR-based approaches have led to the processing of hundreds of millions of samples for the analysis of the SARS-CoV-2 virus [ 6 ]. In addition, molecular methods have been key for the creation of multiple companies, products and jobs [ 7 ].

The development of sequencing technologies and their iterative improvements have been instrumental in advancing the understanding of DNA and RNA, their identification, association with various proteins, their covalent modifications, the function of the genes they carry, and the function of the non-coding portion of DNA and RNA in normal and diseased cells, in pathogenic bacteria and viruses, and in plants [ 8 , 9 ]. By producing RNA-based vaccines, we were able to combat the recent SARS-CoV2 pandemic. This was made possible by sequencing and in vitro nucleotide synthesis technologies [ 10 ].

Gene editing technologies, such as restriction endonuclease digestion, transcription activator-like effector nucleases (TALENs), and the clustered regularly interspaced short palindromic repeats (CRISPR-Cas) system, are an additional development in the field of molecular biology that has aided in the understanding of DNA and genes. There is optimism about the use of CRISPR-Cas9 technology in the treatment of a wide variety of diseases, such as cancer, blood-related diseases, hereditary blindness, cystic fibrosis, viral diseases, muscular dystrophy, and Huntington´s disease, due to its precision and its constant improvement, in comparison with other gene-editing technologies [ 15 ].

Need for novel methods in molecular biology and genetics

There is a global need for the development of novel methods for molecular biology and genetics. Particularly, in the area of human health, there is a need for further approaches that facilitate point-of-care molecular analysis (particularly miniaturized and portable platforms), for infectious and non-transmissible diseases [ 11 ], the development of more efficient methods for DNA sequencing [ 3 ], which facilitate cost-effective genome-wide analysis of patients, among others.

In addition, three key factors would also help push this field forward: additional research comparing the performance of different methods for molecular biology [ 12 ], the broader use of reporting standards (such as the Minimum Information for Publication of Quantitative Real-Time PCR Experiments -MIQE-, which describes details of experimental conditions) [ 13 ], and the increased participation of scientists from the Global South.

Although older techniques, such as x-ray crystallography, gene cloning, PCR, and sequencing, have been instrumental in the study of various aspects of genetics, these techniques have several limitations that result in gaps, missing links, and incomplete understanding of the genome. Advances in these techniques are needed to fill in these missing pieces of the puzzle to better comprehend genetics and accelerate the discovery of the causes of various genetically linkeddiseases. From a technological standpoint, the accuracy of sequencing and coverage across the genome remain major issues, especially for GC-rich regions and long homopolymer stretches of DNA. Furthermore, the short read lengths generated by the majority of current platforms severely restrict our ability to accurately characterize large repeat regions, numerous indels, and structural variation, rendering large portions of the genome opaque or inaccurate. Fragmentation of the genome for sequencing continues to be a major source of disruption in the continuity of the correct genomic sequence [ 14 , 15 ].

Recent advances in CRISPR technology provide hope for the medical treatment of cancer and other fatal diseases. Despite significant advances in this field, a number of technical obstacles remain, including off-target activity, insufficient indel or low homology-directed repair (HDR) efficiency, in vivo delivery of the Cas system components, and immune responses. This requires a substantial amount of technological advancement or the creation of new, superior methods to combat severe diseases with minimal side effects [ 14 , 16 ].

Additional considerations

As high-throughput, automated methods commonly produce very large amounts of data, deeper interaction between wet-lab and dry-lab researchers is required, to facilitate the design of efficient assays [ 17 ] and allow effective analysis and interpretation of results. Interdisciplinary collaborations, between biologists, engineers and professionals in the health sciences, might lead to newer and better methods of addressing current and future needs.

Further collaborations between scientists from academia and industry (in addition to researchers from government agencies) [ 18 ] would help to facilitate the development of novel methods, and aid in promoting their implementation around the world. For many countries, the main barrier to the broad use of molecular methods is the high cost of equipment and reagents [ 19 ]. Strategies aimed at lowering costs would be helpful for multiple institutions around the globe. In terms of intellectual property, fair licensing to institutions in the Global South as well as the implementation of Open Innovation and Open Science policies would be appropriate [ 20 ].

Overview of the current collection

In this current Collection, we are calling for articles showcasing novel methods from molecular biology and genetics, written by scientists from around the world. It is our goal to compile a set of articles that will help to address the challenges faced by the fields of molecular biology and genetics and broaden our understanding of genetic disorders and potential treatment strategies. We invite researchers working on such methods to consider submitting to our collection.

What Is Biology? What Topics Might Biologists Study?

Biology is simply the study of everything that has a form of life. It includes investigations on plants, animals, and everything found in the environment. It is about studying how life forms grow, develop, and interact with each other. Biology essay topics for research encompass all these and more.

This science uncovers many fields where various life forms are studied. It makes sense to look through these fields to help you decide which suits you the best.

Plant Biology research topics are about studying the plants around us. They disclose information about their existence as a part of the ecosystem, their life cycle, resources they can give us, their ability to preserve them from climate changes, and so on. There are many ideas to choose from, but you must focus on a specific one.

Human Biology research topics are all about us. These topics focus on different body parts, such as the human brain, the human immunological system, the nervous system, etc. In addition, you can discuss DNA modifications in humans and explain why genetic disorders occur in your research projects. Various cell research is also common today.

Biology research topics on the environment are in great demand too. For example, climate change is becoming a more significant threat every day. By studying environmental topics in biology for projects and research, we can come up with ways to combat them and preserve ecosystems.

Microbiology research topics delve into things we can’t see. There are trillions of microbes and bacteria all around us. Knowing about them is essential to understanding what makes us sick and how to fight against them. All microbiology research paper topics are pretty complicated yet very engaging to include in your paper research.

Molecular biology topics dive even deeper into the level of atoms and molecules. The various medicines and drugs we take were all created through molecular-biology research. It is one of the areas full of ideas, but there is yet to be much evidence. Science is advancing in this realm but still needs a lot of time. Topics of molecular biology will need days for research only.

Keep in mind that there are more ideas and variations of this science. We offer more examples in further sections of the article about developmental biology, marine biology, evolutionary biology, etc. Explore them and make your writing appealing and meaningful in the eyes of a professor.

How to Choose a Topic for Biology Research Paper?

When choosing a biology project topic, you must be aware of one or more fields of science. Biology research is critical to the present world. By doing research, we can learn more about genetic disorders, immune disorders, mental health, natural disease resistance, etc. Knowing about each of these could save lives in the future.

For those who may not have the time or resources to do their own research, there are research paper writing services that can provide assistance with the project. And we are always here to help you find your own topic among interesting biology research topics. Here we prepared some useful tips to follow.

• Tip 1: The level of interest matters Pay attention to one that interests you, and you might have ideas on how to develop the topic. Passion is fundamental in research, after all.
• Tip 2: Explore the topic Try to narrow things down a bit. If the topic is too broad, you may not be able to cover all aspects of it in one research paper. If it is too narrow, the paper could end up too short. Analyze the topic and the ways to approach it. By doing so, you can strike a balance between the two.
• Tip 3: Discover the recent developments To make your research paper touchable with the present day, you must explore the latest developments in the field. You can find out what kind of research has been done recently by looking at journals. Check out research papers, topics, research articles, and other sources.
• Tip 4: Ensure to get enough resources When choosing a topic, make sure it has plenty of resources available. For example, a research paper on xenobiology or cutting-edge nanobiology might sound attractive. Still, you might have difficulties getting data and resources for those unless you are a researcher at a government lab. Data, resources, complex numbers, and statistics are all invaluable to writing a paper about these topics.

That is why we have selected a range of biological topics. The topics on this list are all hopefully exciting topics for research you could write an excellent paper on. We should also add that easy biology topics to research are rare, and a writer usually needs days to prepare and start writing. Yes, biology research topics for high school students are a bit easier, but still, they need time to explore them.

On the other hand, biology research topics for college students are far more complex and detailed. Some people prefer evolutionary biology research paper topics, and we can agree with this claim. These research areas do have a lot of potential and a lot of data to support the claims. Others prefer cell biology research topics that are a bit specific and fun. Anyway, with this article’s list of easy biology research topics, you will surely find the one matching your interest.

212 Unique Biology Research Topics For Students And Researchers

Every student studying something related to biology — botany, marine, animal, medicine, molecular or physical biology, is in an interesting field. It’s a subject that explores how animate and inanimate objects relate to themselves. The field unveils the past, the present, and what lies in the future of the relationship between the living and nonliving things.

This is precisely why you need custom and quality biology topics for your college and university essay or project. It’ll make it easy to brainstorm, research, and get to writing straight away. Before the deep dive, what is biology?

What Is Biology?

Everyone knows it’s the scientific study of life, but beyond that, biology facilitates the comprehension of living and nonliving things. It’s a branch that explores their anatomy, behavior, distribution, morphology, and physiology.

For example, it understands how genes are classified and constituted into generations. It encompasses various branches, including botany, medicine, genetics, ecology, marine biology, zoology, and molecular biology.

Here are what some of these mean:

Botany: This study of plants examines their structure, physiology, ecology, economic importance, and distribution, among others. It also deals with their biochemical processes, properties, and social interactions between plants. It extends to how plants are vital for human life, survival, and growth and how they play a significant role in stabilizing environmental health. Zoology: Zoology studies animal behavior, brain, structure, physiology, class, and distribution. It’s the general study of the lives of both living and extinct animals. It explains animal classification, the animal kingdom, evolution, habitat, embryology, and life span. Physiology: Physiology deals with the daily functions of the human body: How it works and the factors that make it work. It examines molecular behavior, the chemistry and physics behind locomotion, and how the cells in the living organisms’ body function. It helps understand how humans and animals get sick and what can be done to alleviate pain. Microbiology: Dealing with microorganisms, it examined how viruses, algae, fungi, bacteria, protozoa, and slime molds become parts of human life. They’re regarded as microbes, which play substantial roles in the human biochemical processes, including climate change, biodegradation, biodeterioration, food spoilage, biotech, and epidemiology. Marine Biology: This is the scientific study of organs in the sea. It understands their family classification, how they survive, and what makes wild marine animals different from domesticated and consumable ones. It also explores their interaction with the environment through several processes. The marine biologist studies marines in their natural environment, collects data on their characteristics, human impact on their living, and how they relate with themselves.

Now that you know all these, here are some custom biology topics to research for your university or college essay and paper.

The paper by Andreia Barateiro et al., and, Adelaide Fernandes, from the Faculty of Pharmacy, University of Lisbon, entitled "Women in the field of multiple sclerosis: How they contributed to paradigm shifts" 1 (ed. By E.Ž), gives perspectives on the paradigm shift in the multiple sclerosis (MS) field of research as performed by women. Authors claim: "History is full of women who made enormous contributions to science. While there is little to no imbalance at the early career stage, a decreasing proportion of women is found as seniority increases." The authors emphasize the new insights on MS sparked by remarkable women that have shifted paradigms by pointing to cognitive impairment, white and gray matter pathology, immune response, and the gut interplay on MS diagnosis, progression, and/or therapy.MS is an autoimmune disorder of the central nervous system (CNS), with evident paradigm shifts in the understating of its pathophysiology. In MS the immune system becomes overactivated and attacks the myelin sheath surrounding axons. The resulting demyelination disrupts the communication signals to and from the CNS. Classically, MS was viewed to cause mostly physical and motor disabilities. However, it is now recognized that cognitive impairment affects more than 50% of MS patients. Another shifting paradigm was the involvement of gray matter in MS pathology, formerly considered to be a white matter disease. In accordance with the gut-brain connection of brain pathologies, the gut microbiota were shown to influence not only different susceptibilities to MS pathology, but it can also modulate the course of disease. Not at least, the role of microRNAs has been investigated in MS, either as potential biomarkers or therapeutic agents.In the paper by Thien Hoang Minh Cao, Anh Phuc Hoang Le et al., and Huong Thi Thanh Ha from the Vietnam National University, Ho Chi Minh City, Vietnam "Plasma cell-free RNA profiling of Vietnamese Alzheimer's patients reveals a linkage with chronic inflammation and apoptosis: a pilot study" 2 (ed. by Ö.S.) profiles of cfRNA in Caucasian AD patients have been investigated. Their study examined the gap and contributed to the development of point-of-care AD diagnosis. Namely, circulating cell-free RNA (cfRNA) is a potential hallmark for early diagnosis of Alzheimer's Disease (AD) as it construes the genetic expression level, giving insights into the pathological progress from the outset.The paper by Zi-Wen Wang et al. and, Ling Zhao from Chengdu University of Traditional Chinese Medicine, Chengdu, China entitled "Brain structural and functional changes during menstrual migraine: Relationships with pain" 3 , (ed. by Ö.S), menstrual migraine (MM) was explored. The authors investigated gray matter volume and functional connectivity alterations in patients with MM. Their results suggest that the anterior cingulate cortex (ACC) may be an important biomarker in MM, and its structural and functional impairments are significantly associated with the severity of pain and pain-related impairment of emotion in patients with MM. "The role of primed and non-primed MSC-derived conditioned media in neuroregeneration" 4 was investigated by Nikola Hudáková et al., and, Dasa Cizkova from the University of Veterinary Medicine and Pharmacy in Kosice, Košice, Slovakia and Institute of Neuroimmunology, Slovak Academy of Sciences, Bratislava, Slovakia (as edited by Jolanta Dorszewska). With growing significance in nervous system repair, mesenchymal stem cell-derived conditioned media (MSCCM) have been used in cell-free therapies in regenerative medicine. However, the immunomodulatory and neuroregenerative effects of MSCCM and the influence of priming on these effects are still poorly understood. The results highlight the potential of primed and nonprimed MSCCM as a useful therapeutic tool for neurodegenerative diseases.In the review paper written by one of the Guest Co-editors, Eva Žerovnik from Jožef Stefan Institute, Ljubljana, Slovenia "Human stefin B: from its structure, folding, and aggregation to its function in health and disease" 5 (as edited by Andrei Surguchov) structural, functional and pathological sides of human stefin B (cystatin B) were described. Mutations in the gene for cystatin B cause progressive myoclonic epilepsy type 1 (EPM1), which also is, apart from epileptic syndrome, a neurodegenerative disorder. Function-wise, human stefin B primarily acts as a cysteine cathepsin inhibitor, however, it also exhibits alternative functions. It has been shown that stefin B is oligomeric in cells and that it has a specific role in the physiology of the synapse and in vesicular transport. It plays a protective role against oxidative stress, likely via reducing mitochondrial damage and reactive oxygen species (ROS). Furthermore, lack of stefin B results in NLRP3 inflammasome activation, followed by increased inflammation and ROS. Primarily the cytosolic protein, it exerts an important role in the nucleus, where it prevents cleavage of the N terminal part of histone 3 by inhibiting cathepsins L and B, regulating transcription and cell cycle.The paper by Zala Slabe et al., and, Dick F Swaab from the Faculty of Medicine, University of Ljubljana, Slovenia and the Institute of the Royal Netherlands Academy of Arts and Sciences, Amsterdam, Netherlands, respectively "Increased pituitary adenylate cyclase-activating peptide genes expression in the prefrontal cortex in schizophrenia in relation to suicide" 6 (ed. by E.Ž), discusses a role of pituitary adenylate cyclase-activating peptide (PACAP) in suicide victims. PACAP is a stress-related neuropeptide that is produced in several brain areas. It acts by 3 receptors: PACAP type-1 (PAC1), vasoactive intestinal peptide (VIP) -1 and -2 (VPAC1 and 2). Data on polymorphisms in PACAP and PAC1 indicate a relationship of the PACAP system with schizophrenia (SCZ). In their study, the dorsolateral prefrontal cortex (DLPFC) and anterior cingulate cortex (ACC) of 35 SCZ patients and 34 matched controls were included. An increase in all PACAP-related genes was present in SCZ-N male patients compared to SCZ-N females. Changes in expression in PACAP-related genes in relation to SCZ, suicide and gender were observed. There was a higher PACAP-related gene expression observed in SCZ patients in the ACC and in suicide victims with SCZ in the DLPFC.Furthermore, original research was performed by the group of Francisca C. Bronfman from the Faculty of Medicine and Faculty of Life Sciences, Universidad Andres Bello, Santiago, Chile (ed. by E.Ž) "PLC-gamma-Ca+2 pathway regulates axonal TrkB endocytosis and is required for long-distance propagation of BDNF signaling" 7 . In this work, brain-derived neurotrophic factor (BDNF) and its tropomyosin receptor kinase B (TrkB) were studied. These proteins regulate dendritic growth and maintenance in the central nervous system (CNS), Namely, after binding of BDNF, TrkB is endocytosed into endosomes and continues signaling within the cell soma, dendrites, and axons. The authors have shown that the activity of PLC-γ is required for BDNFdependent TrkB endocytosis, suggesting a role for the TrkB/PLC-γ signaling pathway in axonal signaling endosome formation.The group of Irena Smaga from the Maj Institute of Pharmacology Polish Academy of Sciences, Kraków, Poland contributed original research about post-delivery depression in the offspring: "A maternal high-fat diet during pregnancy and lactation induced depression-like behavior in offspring and myelin-related changes in the rat prefrontal cortex" 8 (ed. by Ö.S.).All in all, we with the Co-Editor are proud for the women contributors, who took the challenge to present their important works.

A universal framework for spatial biology

by Luca Marconato, Kevin Domanegg and Lisa Vollmar, European Molecular Biology Laboratory

Biological processes are framed by the context they take place in. A new tool developed by the Stegle Group from EMBL Heidelberg and the German Cancer Research Center (DKFZ) helps put molecular biology research findings in a better context of cellular surroundings, by integrating different forms of spatial data.

In a tissue, every individual cell is surrounded by other cells, and they all constantly interact with each other to give rise to biological function. To understand how tissues work or malfunction in diseases such as cancer, it is crucial to not only learn the characteristics of every cell, but also account for their spatial context. Quantitative characterization of cells in the context of the physical space they inhabit is key to understanding complex systems.

The technologies enabling these types of exploration are called spatial omics technologies, and their progressing development is contributing to the rise in popularity of spatial biology. Such technologies can give detailed information about the molecular makeup of individual cells and their spatial arrangement.

However, these technologies focus on different characteristics of a cell—such as RNA or protein levels, and the resulting datasets are managed and stored in diverse ways. To solve this challenge, a collaborative project led by the Stegle Group developed SpatialData, a data standard and software framework which allows scientists to represent data from a wide range of spatial omics technologies in a unified manner.

Technology development for spatial biology

Over the last decade, numerous technologies have been developed by both academia and industry for spatially visualizing tissues, cells, and subcellular compartments. However, each technique focuses on a small number of desirable characteristics and presents related trade-offs. For instance, Visium from 10x Genomics captures information about the expression of all genes in a tissue, but does not provide single-cell resolution.

In contrast, the 10x Genomics Xenium assay, MERFISH, or the MERSCOPE platform from Vizgen yield fine-grained maps of gene expression with subcellular resolution. However, these assays are currently limited to a few hundred preselected genes. And the list of such technologies, each providing a small slice of the full picture, keeps growing.

Challenges of spatial omics technologies

This heterogeneity of technologies is reflected on the computational side by an even greater heterogeneity of file formats: each technology comes with its own storage format, and often data generated by the same technology can be stored in multiple formats.

Practically, this brings several challenges to the analysis of spatial omics data. Visualization and analysis methods are usually tailored to a specific technology, which limits data compatibility and makes it hard to integrate different methods into a single analysis pipeline. However, for a holistic understanding of a biological system, it's important to simultaneously look at different cell characteristics or samples from different locations.

Omics technologies generate enormous amounts of data (terabytes of images, millions of cells, billions of single molecules), demanding optimized engineering solutions. Hence, spatial biology urgently needs a universal framework that can integrate data across experiments and technologies, and provide holistic insights into health and disease. This is where SpatialData steps in.

SpatialData—a framework to unite them all

"There is a strong need to establish community solutions for the management and storage of spatial omics data. In particular, there is a need to develop new data standards and computational foundations that allow for unifying analysis approaches across the full spectrum of different spatial omics technologies that are emerging," said Oliver Stegle, Group Leader at EMBL in the Genome Biology Unit, and head of the Computational Genomics and Systems Genetics division at the German Cancer Research Center (DKFZ).

"A first major step in this direction is SpatialData, a data standard and software framework that bridges and adapts previous data management concepts from single-cell multi-omics to the spatial domain."

SpatialData unifies and integrates data from different omics technologies, bridging state-of the-art-technologies with a framework that allows for computationally performant access and manipulation of the data.

This tool was introduced in a Nature Methods publication , authored by Luca Marconato during his Ph.D. at EMBL in the Stegle Group, a joint degree with the Faculty of Bioscience of the University of Heidelberg.

"We developed the SpatialData framework to alleviate the data representation challenges when studying spatial biology, so that the researcher can focus on the biological analysis, rather than being slowed down by tedious data manipulations, otherwise required to even just visualize the data. The framework provides a unified representation and implements ergonomic operations for convenient processing of spatial omics data," said Marconato.

The tool enables any researcher to import their data and perform tasks like data representation, processing, and visualization. Additionally, it gives the option to interactively annotate the data, and save it in a language-agnostic format, facilitating the emergence of analysis strategies that combine methods from different programming languages or analysis communities.

The framework has been developed as a collaborative project between multiple institutions such as the DKFZ, the Technical University of Munich, the Helmholtz Center Munich, German BioImaging, the ETH Zürich, VIB Center for Inflammation Research in Belgium, as well as the Huber and Saka groups at EMBL.

"We have conducted our research and technological development keeping the benefit for the bigger science community in mind," said Giovanni Palla, co-first author and Ph.D. student at the Helmholtz Center Munich.

"We not only established an interdisciplinary collaboration project between research institutes but also worked closely with developers working with different spatial technologies and in different programming languages to address the problem of interoperability. As a result, our framework is compatible with the vast majority of spatial omics assays from academia and industry.

"Being published openly, other researchers can now freely use SpatialData to manage their own data and have the opportunity to collaborate across various technologies and research topics."

"In our paper, we illustrate three important features of SpatialData," explained Kevin Yamauchi, co-first author and a postdoctoral researcher at ETH Zürich.

"First, we present a standardized interface and unified storage format (based on the OME-NGFF) for all spatial omics technologies. Second, using the unified representation, we integrate signals from multiple modalities. Here, we transfer annotations across modalities and quantify signals using these transferred annotations. Finally, we present a way to interactively annotate (pathology) images and use the annotations to analyze the associated molecular profiles."

SpatialData provides an interactive representation of data, both on your hard drive and your computer's RAM, which enables the analysis of large imaging data or multiple geometries or cells.

Other prominent key features are the framework's ability to align and annotate omics data in a common coordinate system. Thus, SpatialData enables the efficient management and manipulation of spatial datasets, including the definition of a common coordinate system across sequencing- and imaging-based technologies.

Application in breast cancer

The interdisciplinary team used the SpatialData framework to reanalyze a multimodal breast cancer dataset from 10X Genomics as a proof of concept. This dataset comprises consecutive sections of the same breast cancer block, where each section is analyzed using different technology, like Visium, Xenium, and a separate scRNA-seq dataset.

The study demonstrates the complementary nature of these technologies. "By integrating 10X Xenium and scRNAseq, we mapped the cell types into the space," said Elyas Heidari, a Ph.D. candidate at DKFZ and one of the authors of the study.

"Next, we used 10X Visium to identify cancer clones in space. This can be done because we have transcriptome-wide readouts. Finally, we used the H&E stained microscopy images to identify regions of interest for histopathology annotations. This analysis successfully showcased a unique application of SpatialData in unlocking multi-modal analyses of spatially-resolved datasets."

In the future, a patient's tumor might be analyzed with different technologies commonly used in the clinic, with the data then unified by SpatialData to gain a holistic understanding of the tumor. Furthermore, the interactive interface would allow the doctor to annotate the data, thus enabling detailed analysis of specific tumor regions and characteristics, potentially leading to personalized treatment approaches.

Unveiling the mysteries of cell division in embryos with timelapse photography

With the help of medaka fish, crispr and new imaging techniques, researchers have set a new standard for studying cell division at the very earliest stages of life.

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells -- the cells that have a specialized function, like skin and muscle cells -- they remain elusive in the first cells of our bodies, the embryonic cells. Embryonic mitosis is notoriously difficult to study in vertebrates, as live functional analyses and -imaging of experimental embryos are technically limited, which makes it hard to track cells during embryogenesis.

However, researchers from the Cell Division Dynamics Unit at the Okinawa Institute of Science and Technology (OIST) have recently published a paper in Nature Communications , together with Professors Toshiya Nishimura from Hokkaido University (previously at Nagoya University), Minoru Tanaka from Nagoya University, Satoshi Ansai from Tohoku University (currently at Kyoto University), and Masato T. Kanemaki from the National Institute of Genetics. The study takes the first major steps towards answering questions about embryonic mitosis, thanks to a combination of novel imaging techniques, CRISPR/Cas9 genome editing technology, a modern protein-knockdown system, and medaka, or Japanese rice fish ( Oryzias latipes ). The timelapses that they have produced help answer fundamental questions about the intricate process of equally dividing chromosomes during embryonic mitosis, and simultaneously chart the next frontier of scientific exploration. As Professor Tomomi Kiyomitsu, senior author of the study, describes the timelapses: "they are beautiful, both on their own and because they lay a new foundation for elucidating embryonic mitosis."

Central to the mystery of embryonic mitosis is the crucial step when the chromosomes, which contain all the genetic information of the cell, are aligned and segregated equally into daughter cells. A key player in this process is the mitotic spindle, which is made of microtubules -- long protein fibers used for intra-cellular structure and transport -- that radiates from opposite poles of the spindle and attaches to the chromosomes in the middle. The spindle captures duplicated chromosomes properly and segregates them equally into the daughter cells during division. There are many factors determining spindle formation, and one of these is the protein Ran-GTP, which plays an essential role in cell division of female reproductive cells, which lack centrosomes -- cell organelles responsible for assembling microtubules -- but not in small somatic cells, which do have centrosomes. However, it has long been unclear whether Ran-GTP is required for spindle assembly in vertebrate early embryos, which contain centrosomes but have unique features, like a larger cell size.

In contrast to mammalian early embryos, embryonic cells in fish are transparent and develop synchronously in a uniform, single-cell layer sheet, which makes them significantly easier to track. The medaka turned out to be particularly well-suited for the researchers, as these fish tolerate a wide range of temperatures, produce eggs daily, and have a relatively small genome. Being temperature-tolerant means that the medaka embryonic cells could survive at room temperature, making them particularly suited for long, live timelapse photography.

The fact that medaka produce eggs frequently and have a relatively small genome size makes them good candidates for CRISPR/Cas9-mediated genome editing. With this technology, the researchers have created genetically modified, or transgenic, medaka whose embryonic cells literally highlight the dynamics of certain proteins involved in mitosis.

In studying the timelapses of the developing mitotic spindle in live, transgenic medaka embryos, the researchers discovered that large early embryos assemble unique spindles different from somatic spindles. In addition, Ran-GTP plays a decisive role in spindle formation in early embryonic divisions, but the importance diminishes in later stage embryos. This is possibly because the spindle structure is remodeled as cells get smaller during development, though the exact reason is a subject for future research.

The researchers also discovered that the early embryonic cells do not have a dedicated spindle assembly checkpoint, which characterizes most somatic cells, and which serves to ensure that the chromosomes are properly aligned before segregation. As Professor Kiyomitsu surmises, "the checkpoint is not active, and yet the chromosome segregations are still very accurate. This could be explained by the fact that embryonic cells need to divide very quickly, but it is something that we want to study further."

While genetically modifying the medaka fish and studying the early embryos have led to new key insights into embryonic mitosis, this is just the beginning for Professor Kiyomitsu and the team. In addition to questions related to the diminishing role of Ran-GTP in later stages and the missing spindle assembly checkpoint, he points to the satisfying symmetry of cell divisions in the timelapses: "The spindle formation is characterized by a high degree of symmetry, as the cells appear to be dividing in the sizes and defined directions, and the spindle is consistently in the center of the cells. How can the spindle orient itself so regularly across the cells, and how is it able to find the center every time?"

Moving beyond the timelapses, the team also hopes to further solidify this new foundation with additional medaka gene-lines to serve as models for research in embryonic cells, and at the same time optimize the genome editing process. Eventually, the team wants to test for generalizability of their findings by studying embryonic mitosis in other organisms, and at a later stage, they want to explore the evolution of spindle assembly and embryonic divisions, which would also contribute to a better understanding of human embryogenesis and to developing diagnosis and treatment of human infertility.

"With this paper, we have created a solid foundation," summarizes Professor Kiyomitsu, "but we have also opened a new frontier. Embryonic mitosis is beautiful, mysterious, and challenging to study, and we hope that with our work, we can eventually get a little closer to understanding the intricate processes at the beginning of life."

IU researchers receive $4.8 million grant to study the role of misfolded protein TDP-43 in neurodegenerative diseases

IU School of Medicine Apr 23, 2024

INDIANAPOLIS—A new $4.8 million grant will support researchers from Indiana University School of Medicine and the Medical Research Council Laboratory of Molecular Biology to study how human neurodegenerative diseases are affected by the misfolding of the protein TDP-43. Misfolding occurs when a protein adopts a conformation which differs from the native one.

The researchers, funded by the National Institute of Neurological Disorders and Stroke, have developed an innovative approach to deciphering the role of TDP-43 misfolding in the pathology of frontotemporal dementias, limbic predominant age-related TDP-43 encephalopathy and Alzheimer’s disease. 

“The presence of misfolded proteins in the central nervous system is the hallmark of neurodegenerative diseases,” said Kathy Newell, MD , Jay C. and Lucile L. Kahn Professor of Alzheimer's Disease Research and Education at IU School of Medicine and a principal investigator of the project. “The argument for the pathogenic significance of various misfolded proteins results from the fact that mutations in the various genes encoding those proteins cause distinct genetically determined neurodegenerative diseases. Furthermore, misfolding of those proteins also occurs in sporadic neurodegenerative diseases.”

An international, multidisciplinary team has been assembled with expertise in neuropathology, digital pathology, molecular genetics, biochemistry, protein misfolding, proteomics, structural biology and cryogenic electron microscopy. The team is supported by experts in clinical neurology, protein misfolding and biostatistics, as well as by the Dementia Laboratory’s Brain Library. 

“The protein TDP-43 is central to the pathogenesis of half of all frontotemporal lobar degeneration cases. Finding out how TDP-43, when misfolded, gives rise to multiple proteinopathies is extremely important for the design of diagnostic and therapeutic compounds that will target pathologic TDP-43,” Newell said.

The project is called “Investigating the role of TDP-43 mislocalization, structure, and post-translational modifications in the neuropathologically heterogeneous TDP-43 proteinopathies.”

In addition to Newell, the other principal investigators are Laura Cracco, PhD, MS , assistant research professor of pathology and laboratory medicine at IU School of Medicine and Benjamin Ryskeldi-Falcon, PhD , group leader at the Medical Research Council Laboratory of Molecular Biology in the United Kingdom. This project is the first National Institutes of Health funded research for all three investigators as principal investigators.
