Abstract | OBJECTIVE: METHODS: RESULTS:
TSA inhibited the growth of A549 cells in time- and concentration-dependent manners. The proportion of apoptosis, G0/G1 and G2/M phase increased in accordance with raising of the TSA concentration. The expression of p21 protein was significantly up-regulated and the expression of phosphorylation ERK was significantly down-regulated after A549 cells were treated with TSA. CONCLUSIONS:
Histone deacetylase inhibitor TSA can inhibit the proliferation of human lung cancer cell strains A549 and induce the cell cycle arrest and apoptosis in the A549 cells. This may be related to up-regulation of p21 protein expression and the down-regulation of phosphorylation ERK.
