Expression profiling of MRC5 senescent fibroblasts

ABSTRACT: Microarrays analysis identifies WNT16in senescent fibroblasts. To identify genes expressed in replicative senescence, microarray experiments were conducted in which we compared the RNA expression profile of young MRC5 fibroblasts at population doubling 28 (PDL28) and replicative senescent MRC5 fibroblasts at PDL63. In total, 177 gene probes were upregulated and 338 gene probes were downregulated in senescent versus young MRC5 fibroblasts. Genes were classified based on mapping to KEGG pathways. Upregulated genes were enriched in three KEGG pathways, the Wingless-type MMTV integration site (WNT) signaling pathway (WNT16, PLCB4, CCND2, SFRP1, WNT5B, RAC2), cytokine-cytokine receptor interaction (TNFRSF10D, TNFRSF10B, TNFRSF10C, IL1R2, IL18, VEGFC), and the p53 signaling pathway (CDKN1A, TNFR
