Abstract
AIM: To investigate the expression of β-catenin and vitamin D receptor (VDR) in colorectal carcinoma to explore their roles in colorectal carcinoma pathogenesis.
METHODS: The expression of β-catenin and VDR was detected by immunohistochemistry in 65 colorectal carcinoma specimens and 65 normal colorectal mucosa specimens.
RESULTS: The missing expression of β-catenin on the cell membrane and ectopic expression in colorectal carcinoma specimens and normal colorectal mucosa specimens had a significant difference (P < 0.01). The strongly positive expression of VDR in colorectal carcinoma specimens and normal colorectal mucosa specimens had a significant difference (P < 0.01). The abnormal expression of β-catenin was positively correlated with that of VDR in colorectal carcinoma (r = 0.98, P < 0.01), and both were found to be associated with lymph node metastasis and tumor invasion.
CONCLUSION: Lower expression of VDR may influence β-catenin and activate the Wnt signaling pathway in human colorectal carcinoma. Detecting the abnormal expression of β-catenin and VDR may be helpful for the diagnosis and evaluation of the prognosis of colorectal carcinoma.
