DNA News and Research

RSS

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).

'Nanobee' drug delivery to tumors

When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

Mal-illumination - the silent epidemic

Most of human history has witnessed people living and working outdoors during the light of day, absorbing "life-charging" full-spectrum solar energy from the sky. An average of 10 hours daily in the sunlight, 70 hours weekly, was common for eons.

Chemists rationally design inhibitors against an RNA molecule that causes myotonic muscular dystrophy

Chemists at the University at Buffalo have used rational drug design to synthesize small, cell-permeable molecules that are effective in vitro against two common types of myotonic muscular dystrophy, a result that has implications for potentially curing muscular dystrophy, as well as other diseases.

Changes in mtDNA can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.
