Activation of Aquaporin 5 by carcinogenic <i>Helicobacter pylori</i> infection promotes epithelial‐mesenchymal transition via the MEK/ERK pathway

Abstract

We explored the underlying mechanism and our results indicated that knockdown of AQP5 significantly suppressed H. pylori infection-induced phosphorylation of ERK1/2, MEK and the expression levels of downstream genes. Treatment with an ERK inhibitor suppressed the EMT induced by H. pylori infection. Taken together, this study suggest that pathogenic H. pylori infection promotes AQP5 expression to induce the EMT via the MEK/ERK signaling pathway.
