Abstract:
Objective To investigate the effect of inhibition of Rabll expression on the proliferation and invasion of human bladder cancer cell line T24. Methods T24 cells were transfected with Rabll siRNA, and RNA interference efficiency was determined by performing Western blotting. The effect of inhibition of Rabll expression on cell proliferation, cell cycle progression, and cell invasion was analyzed by performing CCK8, cell cycle detection, and Matrigel invasion assays, respectively. Expression of cell cycle-related proteins cyclin D1 and cyclin E and invasion-related protein matrix metalloproteinase 9 (MMP9) was determined by performing Western blotting and RT-PCR. Results Inhibition of Rabl 1 expression inhibited the proliferation and invasion of bladder cancer cells and downregulated the expression of cell cycle-related proteins cyclin D1 and cyclin E and invasion-related protein MMP9. Conclusion Our results suggest that Rabl 1 functions as a tumor protein and is involved in the progression of bladder cancer.
