Mitochondrial damage caused by some anti-retroviral drugs commonly used to treat HIV, study shows

A class of anti-retroviral drugs commonly used to treat HIV, particularly in Africa and low income countries, can cause premature ageing, according to research published in the journal Nature Genetics. The study shows that the drugs damage DNA in the patient's mitochondria – the 'batteries' which power their cells. The findings may explain why HIV-infected people treated with antiretroviral drugs sometimes show advanced signs of frailty and age-associated diseases such as cardiovascular disease and dementia at an early age.

Green tea may protect DNA from damage, study suggests

Drinking green tea every day for a month may protect against damage at a genetic levels, with benefits linked to the beverage’s antioxidant content, says a new study. Combined results from a human supplementation trial and an in vitro study indicated a 20 percent reduction in levels of DNA damage, while measures of whole-body oxidative stress were unaffected, say findings published in the British Journal of Nutrition.
