Fig. 2From: RARγ-induced E-cadherin downregulation promotes hepatocellular carcinoma invasion and metastasisSilencing RARγ impaires HCC migration and invasion in vitro and metastasis in vivo. a–d Migration (a) and invasion (c) assays were performed in wild-type MHCC-97H cells (shRNA/Control) and in the MHCC-97H cells with stable knock down of RARγ (shRNA/ RARγ), and the relative number of migratory (b) and invasive (d) cells were calculated with Wright-Giemsa staining. e Knockdown of RARγ inhibits HCC metastasis. Representative lung tissue sections from each group were shown by hematoxylin and eosin staining (magnification: × 40). Black arrows indicate lung tissues with matastatic nodules. f The number of lung metastatic foci in each group (n = 6 per group) was counted under the microscope. Statistical significance was determined by a two-tailed, unpaired Student's t-test. **p < 0.01Back to article page
