ABSTRACT
BACKGROUND/AIMS:
TGF-ß1 is beneficial during early liver disease but is tumor-progressive during late stages especially for hepatocellular carcinoma (HCC). Thus, exploring the underlying mechanisms may provide information about a potentially therapeutic role of TGF-ß1 in HCC.METHODS:
Western blot and real-time quantitative PCR were used to quantify FGFR4 expression in HCC cell lines and a normal liver cell line. After constructing the best silencing FGFR4 expression vector, migration and invasiveness of TGF-ß1 in HCC was studied in vitro and in vivo. Western blot was used to study the mechanism of TGF-ß1 induction on FGFR4 expression with various inhibitors.RESULTS:
HepG2 cell lines had the most FGFR4 expression, and data show that silencing FGFR4 suppressed cell proliferation, invasion and migration in HCC induced by TGF-ß1 in vitro and in vivo. Moreover, TGF-ß1 induced FGFR4 expression through the ERK pathway.CONCLUSION:
Promoting FGFR4 expression via the ERK pathway, TGF-ß1 contributes to HCC invasion and metastasis.Palavras-chave
