摘要: PPARB was identified as a target of APC through the analysis global gene expression profiles in human colorectal cancer (CRC) cells. PPARdelta elevated CRCs and repressed by CRC This repression mediated beta-catenin/Tcf-4-responsive elements promotor. The ability PPARs to bind eicosanoids suggested that might be chemopreventive non-steroidal anti-inflammatory drugs (NSAIDs). Reporters containing PPARdelta-responsive were NSAID sulindac. Furthermore, sulindac able disrupt its recognition sequences. These findings suggest NSAIDs inhibit tumorigenesis inhibition PPARdelta, for which is normally regulated APC.
