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 mutant rat model replicates human chronic kidney disease

Chronic kidney disease (CKD) is a major health burden affecting approximately one in ten adults globally. Even with improved treatments, many patients continue to have worsening loss of kidney function, resulting in the need for dialysis or transplantation.

Gut microbiome atlas maps how bacteria establish themselves and shift in inflammatory bowel disease

Researchers created a microbiome-wide atlas mapping more than seven million colonization factor genes across 4,716 human gut microbial species, revealing three putative strategies linked to metabolism, stress resistance, and microbial communication. Applying the framework to inflammatory bowel disease showed that colonization-factor profiles can provide a compact, biologically interpretable view of disease-associated microbiome changes.

Faulty myelin-making brain cells may help drive cognitive decline with age

Researchers found that greater age-related cognitive decline was associated with more dysfunctional oligodendrocytes, reduced NRF2 expression, smaller myelinated axons, and abnormally thicker myelin in human white matter. Experiments in mice showed that deleting NRF2 specifically from oligodendrocytes reproduced key white matter abnormalities and reduced cognitive improvement over time, implicating this pathway in cognitive aging.

Breast milk fats may reflect more than the fats a mother eats

A cross-sectional study of 109 breastfeeding women in the Netherlands found that maternal intakes of omega-3 and omega-6 PUFAs and trans fats were associated with corresponding fatty acid proportions in human milk. The researchers also identified links involving dietary fiber, diet quality and several micronutrients, although whether these relationships reflect direct biological effects or broader dietary patterns remains uncertain.
