HOXA11 and hepatocellular carcinoma: To investigate the function of HOXA11-AS on the proliferation of HCC cells, SMMC-7721 cells and Bel-7402 cells were transfected with sh-HOXA11-AS (sh-HOXA11-AS#1 and sh-HOXA11-AS#2) using shRNA as a negative control (NC); HepG2 cells were transfected with pcDNA3.1/HOXA11-AS, using pcDNA3.1 as a negative control (NC).
