Inhibiting Forkhead box K1 induces autophagy to reverse epithelial-mesenchymal transition and metastasis in gastric cancer by regulating Myc-associated zinc finger protein in an acidic microenvironment.

ABSTRACT:

Background

Forkhead box K1 (FOXK1) is a transcription factor belonging to the Forkhead box (FOX) family and is closely related to the development of various cancers, but the functional mechanism through which FOXK1 regulates autophagy and epithelial-mesenchymal transition (EMT) in the acidic microenvironment of gastric cancer (GC) remains unclear.

Results

Our results indicated that the inhibition of FOXK1 induced autophagy and thus exerted antimetastatic effects in an acidic microenvironment. The dual inhibition of mammalian target of rapamycin (mTOR) and FOXK1 enhanced autophagy and reversed EMT of acidic GC cells. In addition, FOXK1 activated transcription in conjunction with the MAZ promoter.

Conclusion

Together, our results suggest that FOXK1 can be used as an ind
