Knock-down of RRS1 inhibited TPC-1 cells proliferation. a, b Real-time PCR and Western blotting were performed to detect the efficiency of RRS1 knock-down. c Proliferation of TPC-1 cells was expressing shRNA targeted against negative and RRS1. Plotted data were mean ± s.e.m. of three independent experiments. *P < 0.05 from student T-test. d Colony formation assays of TPC-1 cells expressing shRNAs were quantified for relative colony numbers of three independent experiments. *P < 0.05 from student T-test. Three independent experiments were performed
