Forkhead box (FOX) transcription factors regulate the development of several human cancers. However, the role and therapeutic potential of FOXA1 in gastric cancer is still largely unexplored. The results showed a significant (P < 0.05) upregulation of FOXA1 in gastric cancer tissues and cell lines. Silencing of FOXA1 in gastric cells significantly (P < 0.05) decreased their viability through induction of apoptosis. The induction of apoptosis was associated with upregulation of Bax and downregulation of Bcl-2. Additionally, FOXA1 silencing caused activation of caspase-3 and 9 with no apparent effects on the expression of caspase-8 suggestive of intrinsic apoptosis. The transwell cell invasion revealed significant (P < 0.05) decline of cell invasion of gastric cancer cells upon FOXA1 silencing. The FOXA1 knockdown further inhibited the in vivo tumor growth suggestive of its therapeutic potential. Taken together, the findings of the present revealed that FOXA1 regulates the proliferation and development of gastric cancer and may exhibit therapeutic implications in gastric cancer treatment.

Background / Aims: Erinacine A, isolated from the ethanol extract of the Hericium erinaceus mycelium, has been demonstrated as a new alternative anticancer medicine. Drawing upon current research, this study presents an investigation of the molecular mechanism of erinacine A inhibition associated with gastric cancer cell growth. Methods: Cell viability was determined by Annexin V–FITC/propidium iodide staining and migration using a Boyden chamber assay to determine the effects of erinacine A treatment on the proliferation capacity and invasiveness of gastric cancer cells. A proteomic assay provided information that was used to identify the differentially-expressed proteins following erinacine A treatment, as well as the mechanism of its targets in the apoptotic induction of erinacine A. Results: Our results demonstrate that erinacine A treatment of TSGH 9201 cells increased cytotoxicity and the generation of reactive oxygen species (ROS), as well as decreased the invasiveness. Treatment of TSGH 9201 cells with erinacine A resulted in the activation of caspases and the expression of TRAIL. Erinacine A induction of apoptosis was accompanied by sustained phosphorylation of FAK/AKT/p70S6K and the PAK1 pathways, as well as the generation of ROS. Furthermore, the induction of apoptosis and anti-invasion properties by erinacine A could involve the differential expression of the 14-3-3 sigma protein (1433S) and microtubule-associated tumor suppressor candidate 2 (MTUS2), with the activation of the FAK/AKT/p70S6K and PAK1 signaling pathways. Conclusions: These results lead us to speculate that erinacine A may generate an apoptotic cascade in TSGH 9201 cells by activating the FAK/AKT/p70S6K/PAK1 pathway and upregulating proteins 1433S and MTUS2, providing a new mechanism underlying the anti-cancer effects of erinacine A in human gastric cancer cells.
