title: Crude extracts of Euchresta formosana radix inhibit invasion and migration of human hepatocellular carcinoma cells.
abstract: Crude extracts of Euchresta formosana radix (EFR) have previously been observed to induce the suppression of liver cancer Hep3B cell growth and induce apoptosis in response to overexpression of reactive oxygen species, GADD153, Bax and caspase-3, and to decrease the levels of mitochondrial membrane potential in vitro. In this study, the effect of EFR on cell migration and invasion by the human liver hepatocellular carcinoma (HCC) cell line Hep3B was examined. Hep3B cells treated in vitro with EFR migrated and invaded less than cells treated with phosphate-buffered saline (PBS) as a control. EFR inhibited migration and invasion by down-regulating the production of RhoA and ROCK1, FAK, and matrix metalloproteinase-1, -2, -9 and -10 relative to PBS only. These results show that EFR inhibits invasion and migration by liver cancer cells by down-regulating proteins associated with these processes, resulting in reduced metastasis. Thus, EFR should be considered as a possible therapeutic agent for inhibiting primary tumor growth and preventing metastasis.
