Mitochondrial DNA Copy Number Associated With Risk Of Kidney Cancer (August 1, 2008) -- Genetic factors were shown to influence the number of copies of mitochondrial DNA (mtDNA) in healthy cells. A lower mtDNA copy number was associated with an increased risk of renal cell cancer in a case-control study. ... > full story
Autopsies Reveal Changes To DNA In Major Depression And Suicide (August 1, 2008) -- Autopsies usually point to a cause of death but now a study of brain tissue collected during these procedures, may explain an underlying cause of major depression and suicide. Scientists found proteins that modify DNA directly are more highly expressed in the brains of people who commit suicide. ... > full story
