Objective To investigate the antiproliferative effect of combination of sodium butyrate (NaB) and cisplatin (DDP) on non-small cell lung cancer cell line A549 and its possible mechanism. Methods The antiproliferative effects of combination NaB and DDP were evaluated using Cell Counting Kit-8 (CCK-8) assay. The changes of the cell cycle and the apoptosis were observed by flow cytometry. The mRNA expression level of p21 gene was detected by RT-PCR. Results The combination of NaB and DDP could inhibit the growth of A549 cell line in a dose and time dependent manner. The IC
50
of the combination group was 5.44 μmol/L and the IC
50
of DDP group was 10.25 μmol/
L. The combination of NaB and DDP induced cell cycle arrest at G

phase
and induced cell apoptosis and up-regulation of mRNA expression of p21 gene. Conclusion The combination of NaB and DDP has antiproliferative effects on non-small lung cancer cells
and the mechanism may be related to promoting cell apoptosis and inducing the expression of p21 gene.
