PG - 7446-54 LID - 10.4238/2015.July.3.20 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha) is an important pro-apoptotic cytokine, which performs a broad range of immune and inflammatory functions in several vital processes. TNF-alpha-induced apoptosis has been confirmed, however, relatively little is known regarding the role of forkhead box class-O 1 (FOXO1) in mediating TNF-alpha-induced apoptosis in cervical cancer. In our study, we used the well-characterized cervical cancer cell line C-33A to investigate the role of FOXO1. The results showed that the antitumor agent TNF-alpha increased the expression level of FOXO1 (P < 0.05) and enhanced its transcriptional activity (P < 0.05). Furthermore, knockdown of FOXO1 repressed TNF-alpha-induced apoptosis and caspase-3, 8, and 9 expressions (P < 0.05). Collectively, these findings suggest that TNF-alpha upregulated the transcriptional factor FOXO1, leading to an increased expression of apoptotic gene, which leads to an increase in apoptosis.
