Hyperthermia inhibits hypoxia-induced epithelial-mesenchymal transition in HepG2 hepatocellular carcinoma cells

Figure 3 Western blot analysis of E-cadherin and vimentin expression in HepG2 cells. Lanes 1, 2, 3 and 4 represent untreated cells, hypoxia-treated cells, hyperthermia-treated cells and hyperthermia + hypoxia-treated cells, respectively. The bar graphs show the relative expression levels of indicated proteins after normalization to β-actin. ^aP < 0.05 vs untreated cells; ^cP < 0.05 vs hypoxia-treated cells.
