Fig. 2. CBX8 promotes proliferative capacity of HCC cells both in vitro and in vivo.
a Proliferation of HepG2-CBX8, Huh7-CBX8, and their control cells was examined by CCK-8 assay. b Proliferation of SMMC-7721-shCBX8, Sk-Hep-1-shCBX8, and their control cells was examined by CCK-8 assay. c Images (left), growth (middle), and weight (right) of tumors following subcutaneous injection of HepG2-CBX8 or control cells. d Images (left), growth (middle), and weight (right) of tumors following subcutaneous injection of SMMC-7721-shCBX8 or control cells. e Representative images of CBX8 and Ki-67 immunostaining in HepG2-CBX8 and the control xenografts. f Ki-67 immunostaining in SMMC-7721-shCBX8 and the control xenografts. **p < 0.01.
