Additional file 1 of MicroRNA let-7b inhibits cell proliferation via upregulation of p21 in hepatocellular carcinoma

Additional file 1: Figure S1. Inhibition of let-7b on the proliferation of L02 cells. A sponge assay was used to downregulate the expression of let-7b in L02 cells. A CCK-8 assay was employed to detect the proliferation of L02 cells. *P < 0.05.
