Gene

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.

What are Genes?

Deoxyribonucleic acid (DNA) is the chemical information database that carries the complete set of instructions for the cell as to the nature of the proteins produced by it, its life span, maturity, function and death. Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.

Grant supports research into how microglia may spread toxic tau in Alzheimer’s

A researcher with the Glenn Biggs Institute for Alzheimer's and Neurodegenerative Diseases at UT Health San Antonio has received a two-year, $402,500 grant award from the Cure Alzheimer's Fund to study how microglia, the brain's resident immune cells, paradoxically might contribute to the spread of toxic forms of tau protein in the disease.

Genetic mismatch identified as major risk factor in cord blood transplantation

A Japanese study of more than 7,400 patients has identified a genetic mismatch that sharply increases the risk of severe acute graft-versus-host disease (GVHD) following umbilical cord blood transplantation.

Gut microbiome may shape response to GLP-1 drugs, new review suggests

This review examines how GLP-1 receptor agonists and the gut microbiome influence one another through bile acid signaling, short-chain fatty acids, and inflammatory pathways. It explores how microbial composition may shape treatment response and highlights the need for controlled human studies to enable microbiome-informed precision therapy.

Gut bacteria patterns help predict insulin resistance in type 2 diabetes, study finds

Researchers used 16S rRNA sequencing and machine learning to identify gut microbiome patterns associated with insulin resistance severity in people with type 2 diabetes. XGBoost models showed that specific bacterial genera, including Bacteroides and Faecalibacterium, help distinguish individuals with higher insulin resistance from healthy controls.

Brain neurons after exercise drive long-term endurance gains

When you finish a run, your muscles may feel like they did all the work. But researchers at The Jackson Laboratory (JAX) and the University of Pennsylvania (UPenn) have discovered that what happens in your brain after a run may determine whether you gain endurance over time.

Developmental ANGPTL4 deficiency protects mice from colitis and tumors

A novel study using a mouse model has found that the absence of the angiopoietin-like 4 (ANGPTL4) protein during development triggers a long-lasting reprogramming of the immune system that protects against intestinal inflammation.
