New insights into why humans are more susceptible to cancer and other diseasesLondon, UK (SPX) Aug 27, 2012 Chimpanzees rarely get cancer, or a variety of other diseases that commonly arise in humans, but their genomic DNA sequence is nearly identical to ours. So, what's their secret? Researchers reporting in the September issue of the American Journal of Human Genetics, a Cell Press journal, have found that differences in certain DNA modifications, called methylation, might play a role. The researchers discovered hundreds of genes that display different patterns of methylation between the two species. ... read more |
