Researchers speed identification of DNA regions that regulate gene expression
St. Jude Children’s Research Hospital scientists have developed a highly efficient method to address a major challenge in biology—identifying the genetic ‘switches’ that regulate gene expression.
Mount Sinai Researchers Identify Mechanisms That Are Essential for Proper Skin Development
Mount Sinai researchers have discovered that Polycomb complexes, groups of proteins that maintain gene expression patterns, are essential for proper skin development, according to a paper published in Genes & Development on February 18.
Computer model makes strides in search for COVID-19 treatments
A new deep-learning model that can predict how human genes and medicines will interact has identified at least 10 compounds that may hold promise as treatments for COVID-19.
Biochemistry researcher receives National Science Foundation Award
The five-year, $680,500 NSF Faculty Early Career Development Program award will be utilized to gain a better understanding of how improper DNA replication and compaction can cause changes in gene expression in offspring while creating a comprehensive learning environment for aspiring high school-aged and undergraduate scientists who will have significant roles in the research.
Biologists Create “Atlas” of Gene Expression in Neurons, Documenting the Diversity of Brain Cells
New York University researchers have created a “developmental atlas” of gene expression in neurons, using gene sequencing and machine learning to categorize more than 250,000 neurons in the brains of fruit flies. Their study, published in Nature, finds that neurons exhibit the most molecular diversity during development and reveals a previously unknown type of neurons only present before flies hatch.
Estrogenic and anti-estrogenic effects of PFASs could depend on the presence of estrogen
Researchers reporting in ACS’ Environmental Science & Technology have used a combination of laboratory experiments and computer modeling to reveal that PFASs can interact with the estrogen receptor in different ways to influence estrogen-controlled gene expression.
Faculty Receives Grant to Develop Method That Will Integrate Biomedical Gene Expression Data
Rutgers School of Public Health assistant professor, Wei (Vivian) Li, has received a Busch Biomedical Grant to develop a statistical method and software package that will integrate single-cell level gene expression data from multiple patients, studies, and technological platforms to understand disease-associated cell types and RNA contents, helping researchers develop personalized treatments.
September Edition of SLAS Discovery Highlights “Applications of Functional Genomics for Drug Discovery”
September’s edition of SLAS Discovery features the cover article, “Applications of Functional Genomics for Drug Discovery” by Ami M. Kabadi, Ph.D., (Element Genomics), Eoin McDonnell, Ph.D. (Element Genomics), Christopher L. Frank, Ph.D., (Element Genomics), and Lauren Drowley, Ph.D., (UCB Biosciences). The article reviews how functional genomic tools are better able to understand the biological interplay between genes, improving disease modeling and identifying novel drug targets.

The August 2020 issue of Toxicological Sciences includes exciting advances in toxicology research. The edition features pieces on biotransformation, toxicokinetics, and pharmacokinetics; developmental and reproductive toxicology; and more.
Silencing Expression of Specific Gene Variants May Provide Insight for Treatment of Mutation-associated Cardiomyopathy
Article title: Silencing of MYH7 ameliorates disease phenotypes in human iPSC-cardiomyocytes Authors: Alexandra Dainis, Kathia Zaleta-Rivera, Alexandre Ribeiro, Andrew Chia Hao Chang, Ching Shang, Feng Lan, Paul W. Burridge, W. Robert Liu, Joseph C. Wu, Alex Chia Yu Chang, Beth…
Computational gene study suggests new pathway for COVID-19 inflammatory response
A team led by Dan Jacobson of the Department of Energy’s Oak Ridge National Laboratory used the Summit supercomputer at ORNL to analyze genes from cells in the lung fluid of nine COVID-19 patients compared with 40 control patients.
The Power of Epigenetics in Human Reproduction
A multinational research team emphasizes the clinical need to understand the characteristics of epigenetic regulation of reproductive function and the underlying mechanisms of adaptive responses for properly informed decisions on treating patients from diverse backgrounds.
Some types of prostate cancer may not be as aggressive as originally thought
Researchers at the UCLA Jonsson Comprehensive Cancer Center analyzed gene-expression patterns in the most aggressive prostate cancer grade group — known as Gleason grade group 5 — and found that this grade of cancer can actually be subdivided into four subtypes with distinct differences. The findings may affect how people are treated for the disease.
Impaired Immunity, Gene Expression May Explain Higher COVID-19 Risk in People with Diabetes
The behavior of previous coronaviruses together with physiological characteristics of diabetes may help explain why people with diabetes have a higher risk of developing COVID-19, a respiratory disease caused by the novel coronavirus SARS-CoV-2.
Stress during Pregnancy May Negatively Affect Baby’s Muscles
Research in sheep suggests that high levels of a stress hormone during pregnancy may alter gene expression in multiple muscle groups of offspring. These shifts may affect heart, breathing and skeletal muscle function, and could potentially increase risks of inflammation and infection. The study is published ahead of print in Physiological Genomics.
Surprise discovery shakes up our understanding of gene expression
A group of University of Chicago scientists has uncovered a previously unknown way that our genes are made into reality. Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed—using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design.
Technique shows how individual cancer cells react to drugs
A new technique reported in Science offers more detail, at the single cell level, on how large, pooled samples of various cells react to drugs or other agents. The data might reveal mode of action or the effect of genetic differences in varying responses.
Complex Cellular Machine Visualized to Yield New Insights in Cancer
Cellular machines that control chromosome structure, such as the RSC complex, are mutated in about one-fifth of all human cancers. Now, for the first time, scientists have developed a high-resolution visual map of this multi-protein machine, elucidating how the RSC complex works and what role it has in healthy and cancer cells.
