Scientists have rendered the first gene and protein networks of human aging, an important step in understanding the genetic mechanisms of aging. The work led by Joao Pedro de Magalhaes from Harvard Medical School is detailed in the July 30 issue of FEBS Letters. The work involved the integration of all genes, in both humans and animal models, previously shown to influence aging. By using a combination of bibliographic information and modern high-throughput genomics, employing software developed by the team, each gene was placed in the context of human biology. The putative impact of each gene to human aging was calculated by a combination of manual and computational methods, leading to a new holistic view of the genetics of aging. To organize and catalog all the data pertaining the over 200 genes selected, the first curated database of genes related to human aging was developed: GenAge, part of the Human Ageing Genomic Resources also led by Dr. de Magalhaes. Thanks to the help of many other researchers, the Human Ageing Genomic Resources have become, in months, the landmark online website for research on aging, having been recently featured in Nature Reviews Genetics (volume 5, issue 5, page 330) and SAGE
