In the present study, we found that fenofibrate, a PPAR-???? agonist, significantly inhibited cell proliferation and induced apoptosis in colorectal carcinoma cells. In addition, PPAR-???? was expressed in the nucleus of colorectal carcinoma cells, and the expression of nuclear PPAR-???? increased in colorectal carcinoma tissue compared with that of normal epitheliumtissue (P<0.01).Thecorrelation between the expression of nuclear PPAR-???? and clinicopathological factors was evaluated in human colorectal carcinoma tissues, and the nuclear expression of PPAR-???? was significantly higher in well-to-moderately differentiated adenocarcinoma than in mucinous adenocarcinoma (P<0.05). These findings indicate that activation of PPAR-???? may be involved in anticancer effects in colorectal carcinomas, and nuclear expression of PPAR-???? may be a therapeutic target for colorectal adenocarcinoma treatment.}, school = {香川県立保健医療大学}, title = {Activation and Expression of Peroxisome Proliferator-Activated Receptor Alpha Are Associated with Tumorigenesis in Colorectal Carcinoma}, year = {2019} }
