| The present study aimed to investigate the in vivo inhibitory effect of histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) combined with sorafenib on human hepatocellular carcinoma HCCLM3 cells. The nude mice transplanted with HCCLM3 cells were randomly divided into control, SAHA, sorafenib and SAHA+sorafenib groups. The nude mice in the later 3 groups were intragastrically administrated with SAHA (10 mg·kg-1·day-1), sorafenib (10 mg·kg-1·day-1) and SAHA (10 mg·kg-1·day-1) combined with sorafenib (10 mg·kg-1·day-1), respectively, for successive 20 days. Finally, the inhibition rate of tumor was measured. The expressions of MEK1/2, p-ERK1/2, Cyclin D1, Bcl-2, Bax, p53, MMP-2, MMP-9 and uPA in tumor tissues were determined. Results showed... |
