KLF7 expression affect tumor growth of HCC cells in vivo. a MHCC97H cells stably transfected with shKLF7 or shNC were subcutaneously injected into nude mice (n = 5). Four weeks later, mice were killed and photographed. b Tumor volume curves were drawn according to the tumor diameter. c Tumor weight of KLF7-knockdown nude mice was measured. d MHCC97H cells stably transfected with KLF7-overexpressing or empty lentivirus were subcutaneously injected into nude mice (n = 5). Representative images of tumors that striped from the nude mice four weeks later. e Tumor growth curve for the xenograft tumors. f Tumor weight of KLF7- overexpressing MHCC97H cells was presented. **p < 0.01, ***P < 0.001
