The purpose of this article is to research on whether MACC1 can serve as a potential target for gene therapy of human bladder urothelial carcinoma (BUC). In this study, the expression of MACC1 gene was knocked down by RNA interference (RNAi) in the T24 cell (human BUC cell). The transcription level of MACC1 was detected by RT-PCR. Activities of MACC1, caspase-3, caspase-8, Bax and Met (mesenchymal-epithelial transition factor) protein were measured by Western blot. The cell proliferation and apoptosis were detected by MTT and flow cytometry. The cell's invasion ability was performed on Matrigel transwell assay. We also detect MMP2 (metalloproteinase-2) proteins by ELISA. The results showed that the level of MACC1 mRNA and protein was significantly reduced after RNAi. MTT assay showed that the proliferation of T24 cell was decreased due to RNA interference. Apoptosis studies also showed that MACC1 gene interference in T24 loses its anti-apoptotic effects. The expression of apoptosis proteins (Caspase-3, Caspase-8 and Bax) increased significantly due to the MACC1 RNAi. The level of Met protein was down-regulated obviously due to RNAi. Transwell assay showed that invasion abilities of T24 cells were reduced obviously due to MACC1 RNAi. Further studies showed that the secretion of MMP-2 was reduced by RNAi. It can conclude that the ability of proliferation and invasion in T24 cells can be inhibited by RNAi-targeting MACC1. As a result, MACC1 can serve as a potential target for gene therapy of human bladder urothelial carcinoma.
