Notably, oncogenic Ras triggers an irreversible proliferation arrest that is reminiscent of replicative senescence and that is considered a relevant tumor-suppressor mechanism. Here, we have used microarrayed filters to identify genes specifically upregulated in Ras-senescent human fibroblasts. Among the initial set of genes selected from the microarrays, we found the cell-cycle inhibitor p21(Cip1/Waf1), thus validating the potency of the screening to identify markers and mediators of Ras-senescence. A group of six genes, formed by those more highly upregulated during Ras-senescence, was analyzed in further detail to evaluate their specificity. In particular, we examined their expression in cells overexpressing Ras but rendered resistant to Ras-senescence by the viral oncoprotein E1a; also, we have studied their expression during replicative senescence, organismal aging, H(2)O(2)-induced senescence, and DNA damage. In this manner, we have identified a novel gene, RIS1 (for Ras-induced senescence 1), which is not upregulated in association to any of the above-mentioned processes, but exclusively during Ras-senescence. Furthermore, RIS1 is also upregulated by the transcriptional factor Ets2, which is a known mediator of Ras-induced senescence. Interestingly, RIS1 is located at chromosomal position 3p21.3 and, more specifically, it is included in a short segment of just 1 Mb previously defined by other investigators for its tumor-suppressor activity. In summary, we report the identification of a novel gene, RIS1, as a highly specific marker of Ras-induced senescence and a candidate tumor-suppressor gene."xsd:string
