In an attempt to explore the effects of miR-15b-5p on the growth of HCC cells by targeting and suppressing Rab1A, we purchased shRab1A and its control from GeneChem, (Shanghai, China), which induced about 50% decrease of Rab1A expression at the mRNA levels in SMMC-7721 cells and Hep3B cells (Figure 3A). The gene discussed is RAB1A; the disease is hepatocellular carcinoma.
