ABSTRACT
Objective:To examine the expression of CLC-3 in colorectal tissues and the effect of CLC-3 on the viability and invasion of colorectal cancer (CRC) SW480 and SW620 cells. Methods:The mRNA levels of CLC-3 in CRC cell lines were determined by RT-PCR. CLC-3 expression was inhibited by adding DIDS or NPPB to the CRC cells. Subsequently, cell viability and invasion were assessed by CCK-8 assay and Transwell assay, respectively. In addition, the effects of DIDS and NPPB on the Wnt orβ-catenin signaling pathways were de-termined by Western blot analysis. Results:The mRNA level of CLC-3 was remarkably increased in the CRC tissues compared with that in normal colorectal tissues (P<0.05) and was positively correlated with the T stage of CRC. The blockade of CLC-3 inhibited the viability and invasion of CRC cells (P<0.05). The expression ofβ-catenin, C-myc, cyclin D1, Ki-67, and survivin were evidently reduced by the in-hibition of CLC-3 (P<0.05). Conclusion:The inhibition of CLC-3 decreases the cell viability and invasion of CRC cells by reducing the ex-pression of the proteins related to the Wnt orβ-catenin signaling pathway.
