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.

New drug class shows major promise for shrinking nerve tumors

A scientist at Cincinnati Children's who has hunted for decades for ways to shrink the painful and disfiguring nerve tumors caused by neurofibromatosis type 1 (NF1) has made a new breakthrough in the quest.

Two scientists win Horwitz Prize for Rett syndrome breakthrough

Columbia University will award the 2026 Louisa Gross Horwitz Prize to Adrian Bird and Huda Zoghbi for their pioneering work on epigenetic regulation in the nervous system and its role in human neurological disease, particularly Rett syndrome.

Semaglutide extends lifespan and slows physiological aging in healthy mice

A National Institutes of Health (NIH)-funded study has shown that the GLP-1 drug semaglutide extended lifespan in older, healthy mice by tempering the detrimental effects of aging.

Harvard scientists discover entirely new gene regulation system in mammals

For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries the instructions for a single kind of protein.

Genetic marker links popular seizure drug to life-threatening reaction

A genetic marker already used to flag risk of a life-threatening reaction to the antibiotic vancomycin also identifies patients at risk of that reaction to lamotrigine - and it is missing from the gene panels clinicians order before prescribing the drug, Vanderbilt Health-led researchers report Sept. 2 in JAMA Network Open.

Study identifes genetic variants that shape human personality traits

An international consortium of researchers found that more than 1,200 different genetic variants are associated with the Big Five personality traits - and surprisingly, these personality genetics are linked to dozens of life outcomes.

Researchers discover dozens of genes tied to OCD and tic disorders

A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk for obsessive-compulsive disorder (OCD) and chronic tic disorders – providing what two researchers said is the most detailed biological understanding of how these conditions develop – and how they might eventually be treated.

Coffee’s link to Parkinson’s risk may depend on how your body handles caffeine

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metabolizer AA carriers, while higher intake was associated with increased risk among AC and CC carriers, although the observational findings do not establish causality and sex-specific patterns require cautious interpretation.

New scLS algorithm advances gene expression trajectory analysis

Single-cell RNA sequencing (scRNA-seq) is a method to measure gene expression of individual cells, allowing observation of various cellular processes, including cell differentiation, the cell cycle, and stimulus-response for each unique cell instead of averaging across millions of cells.
