Histone deacetylase inhibitor restrained proliferation of human cervical cancer cells
摘要
Abstract
OBJECTIVE: To investigate the inhibitory effect of paclitaxel and SAHA on human cervical cancer cells. METHODS:Human cervical cancer (HeLa) cells were treated with paclitaxel (10 nmol/L),SAHA (10 μmol/L), or paclitaxel (10 nmol/L) + SAHA (10 μmol/L) for 24 hours or 48 hours. The inhibitory rates of HeLa cells were determined by MTT assay. p27 mRNA levels were determined by RT-PCR assay,protein levels of Ac-H4 were identified by Western blot and IC of paclitaxel was calculated by SPSS 16.0. RESULTS:Results from the MTT assay show that the inhibition50 rates from exposure to the combination of paclitaxel and SAHA were significantly higher than those from the single treatment groups (P<0.01). Similarly,RT-PCR assay show that the p27 mRNA levels from the combined treatments were significantly higher than from single treatments (P<0.01). From combined treatments,the inhibitory rates were 54.27%± 4.02% with 24 h treatment and 77.02%±3.86% with 48 h treatment,the mRNA level was 10.601±0.673,the proteinlevel of Ac-H4 was 1.282±0.033,and IC was reduced significantly. CONCLUSION:SAHA in combination with50 paclitaxel significantly inhibited HeLa cell proliferation by enhancing the level of histone acetylation and inducing the expression of tumor suppressor genes in vitro.关键词
