Abstract

BACKGROUND: β-catenin has a critical role in the homeostasis processes. Wnt/β-catenin signaling mainly involved in the modulation of cancer cell development. AIM: This research aimed to investigate the differences of β-catenin expression observed in the form of nucleus– cytoplasm ratio, the differences of E-cadherin and N-cadherin expressions, and the correlation between N-cadherin and E-cadherin and β-catenin cytoplasm in Dukes D stage colorectal cancer (CRC), which is an advanced stage and has experienced metastasis. MATERIALS AND METHODS: This study followed an experimental research design. The processes of culture manufacturing and subculture preparation of Dukes D stage CRC cell line model were performed before the administration of β-catenin, E-cadherin, and N-cadherin antibodies. The next process was staining using fluorescein-5-isothiocyanate and rhodamine, and observations were performed using a confocal microscope. The number of cells was counted, and the intensity of antibody expression based on the arbitrary unit was measured. RESULTS: There was a significant difference between the expression of β-catenin nucleus and cytoplasm expression (p = 0.00), as well as between E-cadherin expression and N-cadherin expression (p = 0.00). In addition, a correlation also existed between an increased N-cadherin expression and decreased E-cadherin expression and β-catenin cytoplasm in Dukes D stage CRC, but the results were not significant (p = 0.837 and p = 0.108). CONCLUSION: In advanced-stage CRC (Dukes D), the Wnt signaling proved to be active and was characterized by a high expression of β-catenin nucleus, it activates the target gene. Similarly, at the Dukes D stage, N-cadherin expression increased whereas E-cadherin expression decreased in which causing the translocation of β-catenin into the nucleus.
