【Abstract】ObjectiveTo investigate the role of PPARδ in the pathogenesis of colorectal cancer.
MethodsLiteratures about PPARδ and the pathogenesis of colorectal cancer were reviewed and analyzed.
ResultsPPARδ is expressed in the nucleuses of glandular epithelia lining colon and rectum. It is normally suppressed by wild-type adenomatous polyposis coli (APC) but is up-regulated by enhanced β-catenin/T cell factor-4 (TCF-4) binding to TCF-4-responsive elements in the PPAR promoter when an inactivating APC mutation occurs, which indicates PPAR is a potential downstream target of the APC/β-catenin/TCF-4 signaling pathway in colorectal cancer. Consistent with PPAR’s role as an APC/β-catenin/TCF-4 target, some studies reported that PPAR mRNA is frequently overexpressed in colorectal cancers of both humans and rodent animals, which indicates that PPAR is relevant to the tumorigenesis of colorectal cancer.
ConclusionPPARδ is closely related with the pathogenesis of colorectal cancer.
