Sorafenib suppressed the in vivo collagen I-induced tumor progression of heat-treated residual HCC cells. a Mice with the tumors derived from heat-exposed residual MHCC97H cells with collagen I were subjected to treatment. Compared with the control group, sorafenib significantly inhibited tumor growth. b The mRNA expression of Ki-67, twist and Nanog were down-regulated in the sorafenib group. c The changes of PCNA, Nanog, vimentin, E-cadherin, N-cadherin, and ERK activation were detected by Western blot. The p-ERK levels were normalized for ERK. Expression levels of E-cadherin, PCNA, vimentin, N-cadherin and Nanog were normalized to GAPDH. d The immunohistochemical staining of PCNA, E-Cadherin, Nanog and phosphorylated ERK in the tumors (scale bar, 50 μm). **, P < 0.01; *, P < 0.05
