Gene News and Research

RSS

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

New Lab-Grown Lip Cells Could Transform Research and Treatment for Disfiguring Lip Conditions

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair effectively. Basic research is essential to improving these treatments, but until now, models using lip cells -; which perform differently to other skin cells -; have not been available.

Integrating Multiple Scales to Understand Brain Function

A long-standing goal of neuroscience is to understand how molecules and cellular structures on a microscale give rise to communication between brain regions at the macroscale. A study published in Nature Neuroscience now identifies, for the first time, hundreds of brain proteins that explain inter-individual differences in functional connectivity and structural covariation in the human brain.

Unraveling the Spatial Complexity of Gene Expression with Seq-Scope

A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.

Innovative Genomic Technology Uncovers Mechanisms of Marjolin's Ulcer

Researchers utilized specialized genomic technology at the University of Calgary to enhance our understanding of Marjolin's ulcer (MU), a rare, highly aggressive skin cancer that affects chronic wounds that can often arise from established scars like those caused by severe burns.

F-Actin Accumulation Impairs Brain Function in Aging Fruit Flies

Humans aren't the only ones who grow forgetful as they age -; fruit flies do, too. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that comes with aging.

Zebrahub Offers Unprecedented Insight into Embryonic Development

When early cartographers undertook perilous expeditions to map unknown corners of the world with sextants, compasses, and hand-drawn diagrams, it's unlikely they imagined that someday anyone with an internet connection would have access to a seamless view of the entire planet from the comfort of their own home.

Study Reveals Role of Gut Microbes in Enhancing Children's Health

To address childhood malnutrition -; which affects 200 million children globally -; researchers at Washington University School of Medicine in St. Louis developed a therapeutic food that nourishes the collections of beneficial microbes that reside in the gut, and improves children's growth and other measures of their health.
