A multidimensional systems biology analysis of cellular senescence in aging and disease

Background Cellular senescence, a permanent state of replicative arrest in otherwise proliferating cells, is a hallmark of aging and has been linked to aging-related diseases. Many genes play a role in cellular senescence, yet a comprehensive understanding of its pathways is still lacking. Results We develop CellAge ( http://genomics.senescence.info/cells ), a manually curated database of 279 human genes driving cellular senescence, and perform...
