DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Male hormones can reverse biological drivers of aging, study shows

Telomerase, an enzyme naturally found in the human organism, is the closest of all known substances to a "cellular elixir of youth." In a recent study, Brazilian and US researchers show that sex hormones can stimulate production of this enzyme.

Adding DNA sequencing to newborn screenings may increase early diagnosis of cystic fibrosis

A study by researchers at Children's Hospital Los Angeles, Brigham and Women's Hospital and the California Department of Public Health suggests that all babies with a known mutation for cystic fibrosis (CF) and second mutation called the 5T allele should receive additional screening in order to better predict the risk of developing CF later in life.

Study reveals unexpected process for acquiring chemoresistance in breast cancers

A laboratory study has revealed an entirely unexpected process for acquiring drug resistance that bypasses the need to re-establish DNA damage repair in breast cancers that have mutant BRCA1 or BRCA2 genes.

Study uncovers new drug-gene mutation combinations that can kill cancer cells

In an effort to expand the number of cancer gene mutations that can be specifically targeted with personalized therapies, researchers at University of California San Diego School of Medicine and Moores Cancer Center looked for combinations of mutated genes and drugs that together kill cancer cells.

Eating more healthy fats may lower type 2 diabetes risk

Eating more unsaturated fats, especially polyunsaturated fats, in place of either dietary carbohydrate or saturated fats lowers blood sugar levels and improves insulin resistance and secretion, according to a new meta-analysis of data from 102 randomised controlled feeding trials in adults.
