We studied the association of SNPs in the IL-6 (-174G>C), IL-8 (-251T>A), TNFalpha (-308G>A), ICAM-1 (R241G and K469E), and PPARgamma (Pro12Ala) genes and the risk of CRC.
We report a novel PPARG germline mutation in a patient affected by colorectal cancer that replaces serine 289 with cysteine in the mature protein (S289C).
Together, these results suggest that miR-145 is a novel target of PPARγ, acts as a tumor suppressor in CRC cell lines and is a key regulator of intestinal cell differentiation by directly targeting SOX9, a marker of undifferentiated progenitors in the colonic crypts.
Thus, codeficiency of Cav1 and adenomatous polyposis coli facilitated formation of CRC, and activation of PPARg may offer novel strategies for treatment of CRC.
This study shows that PPARgamma agonists up-regulate KLF4 expression in receptor-dependent manner, and KLF4 was identified as a novel transcription factor that controls NAG-1 promoter activity in human and mouse colorectal cancers.
This meta-analysis suggests that the Ala allele of the PPARgammaP12A polymorphism might be a protective factor for colorectal cancer, but a risk factor for gastric cancer.
These findings suggest that PPARgamma gene polymorphism may be implicated with the development of colorectal cancers, in which K-ras gene is not mutated.
The purpose of this study was to evaluate whether EP(1-4) subtype, PPAR gamma receptor and COX-1/COX-2 expression in colorectal cancer are related to tumor-specific mortality.
Since higher levels of miR-130b are found in advanced tumor stages (III-IV), we propose a novel role of the miR-130b-PPARγ axis in fostering the progression toward more invasive CRCs.
No evidence that polymorphisms in CYP2C8, CYP2C9, UGT1A6, PPARdelta and PPARgamma act as modifiers of the protective effect of regular NSAID use on the risk of colorectal carcinoma.
