Abstract:
Objective To explore the influence of cathepsin B (CatB) expression on the ability of adhesion and invasiveness of colorectal cancer cells. Methods Human colon cancer cell line LoVo and rectal cancer cell line HR-8348 were used in the present study. The total length of CatB mRNA was cloned and transfected into the cells, and the CatB expression was detected by RT-PCR. Cell adhesion was detected with Matrigel and invasiveness was assessed with transwell method. Results CatB mRNA expression was detected and enhanced expression was found in LoVo and HR8348 cells tranfected with pcDNA3CatB. Cell adhesion rates to Matrigel stromatin in control LoVo cells, empty vector transfected cells and CatB transfeted cells were 0.461 6?0.148 7, 0.412 1?0.215 8 and 0.691 6?0.150 8, respectively. The adhesive rate of CatB transfected LoVo cells was higher than that of the control cells and the empty vector transfected cells with significant differences (F=5.839 0, P
