Finding Longevity Genes in Humans
PR Newswire: Prolexys Pharmaceuticals announced today the publication of the discovery of genes that are likely to have a role in the aging process of humans. The findings result from research on the human equivalents of proteins from simple animals which confer long life in those species. The evidence suggests that these proteins are more likely to interact with other proteins in a large atlas of mapped interactions. Furthermore, the investigators were able to show that the protein associations also correlate with differences in gene expression between young and old humans. Though the existence of longevity-extending genes has been known for experimental organisms such as yeast, roundworms and flies, this is the first demonstration that similar genes have a role in the aging process of humans.
