Abstract:
Background and objective Metastasis-associated protein 3 (MTA3) was originally found as a member of a small protein family (including MTA1, MTA2 and MTA3), and it has been proven that MTA3 had different roles in dif-ferent types of human cancers. hTe aim of this study is to explore the function of MTA3 to regulate the cell apoptosis in lung cancer. Methods Western blot and Real-time PCR were used to detect the expression level of MTA3 atfer transfection in non-small cell lung cancer (NSCLC) cells A549 and H157. Apoptosis analysis was used to detect the change of cell apoptosis with upregulated/downregulated of MTA3, and Western blot was used to detect the the expression of the protein related with apop-tosis, while downregulate the expression of MTA3 in NSCLC cells A549 and H157. Results Downregulated of endogenous MTA3 could promote apoptosis in NSCLC cells, meanwhile, siMTA3 could upregulate the protein of BAX, Cleved-Caspase-3, p-PARP, and dowmregulate the protein of Bcl-2. Conclusion hTe data we present here indicate that MTA3 suppress apoptosis of A549 an H157 cells by inhibiting BAX, PARP expression.
