https://www.selleckchem.com/products/k03861.html Animal studies indicated that P1 promoter-driven hepatocyte nuclear factor 4 alpha (HFN4A) prevents carcinogenesis in colitis. But the function of total HNF4A protein has not been fully investigated, and it was assumed to be involved in the colitis-neoplastic sequence. The aim of this study was to determine the clinical value of total P1-/P2-driven HNF4A combined with β-catenin in the colitis-neoplastic sequence. A total of 69 samples, including 4 normal colon tissues, 16 sporadic colorectal cancer (CRC) tissues, 35 inflammatory bowel disease (IBD) tissues, and 14 IBD-associated low-grade dysplasia tissues, were collected to assess P1-/P2-driven HNF4A and β-catenin expressions by immunohistochemical assay. In addition, a colonic epithelial cell line Caco2 with stable P1-/P2-driven HNF4A knockdown was constructed. β-Catenin expression and skeleton structure were determined in the transfected cells by western blot analysis and immunofluorescence assay respectively. Increased expression of nuclear P1-/P2-driven HNF4A was observed in the colitis-associated colorectal neoplasm and sporadic CRC samples, compared with that in colitis samples. The parallel alterations between cytoplasmic β-catenin and nuclear P1-/P2-driven HNF4A were also verified. Silencing of P1-/P2-driven HNF4A expression in Caco2 cells decreased β-catenin expression and F-actin formation. Our results confirmed the elevated expressions of nuclear P1-/P2-driven HNF4A and cytoplasmic β-catenin in the colitis-neoplastic sequence, and both of them may be used as potential biomarkers to predict low-grade dysplasia.
