RBM15B and hepatocellular carcinoma: To clarify the role of RBM15B in regulating the progression of HCC, we selected HCC cell lines HCC-LM3 and Huh-7 with relatively high RBM15B levels to stably knockdown RBM15B expression and selected the HCC cell line Hep-G2, which has a relatively low RBM15B level, to overexpress RBM15B (Figures 2A, S2A).
