Nm23-H1 inhibits hypoxia induced epithelial-mesenchymal transition and stemness in non-small cell lung cancer cells.
In this study, nm23-H1 was down regulated in epithelial-mesenchymal transition (EMT) and stemness enhancement under cobalt chloride (CoCl2)-induced hypoxia in NSCLC cells. Moreover, knocking down of nm23-H1 by shRNA apparently promoted hypoxia induced EMT and stemness, which was entirely suppressed via over expression of nm23-H1. Mechanistically, the Wnt/β-catenin signaling pathway was found to participate in the nm23-H1-mediated process. Besides, XAV939 prohibited cell EMT and stemness which could be impaired by knocking down of nm23-H1, while stable transfection of nm23-H1 attenuated hypoxia phonotype induced by lithium chloride (LiCl). Generally, our experiment provided evidence that nm23-H1 can reverse hypoxia induced EMT and stemness through the inhibition of the Wnt/β-catenin pathway, which may furnish a deeper perspective into the better treatment or prognosis for NSCLC.
