A novel role for the urease virulence factor in the induction of HIF-1α activity in gastric cells by Helicobacter pylori

A recently published study from our lab demonstrated that H. pylori activation of the PI3K-AKT-mTOR pathway in gastric cells, increased hypoxia-induced factor (HIF)-1α expression, which accelerated the post-translational down-regulation of Cyclin D1.
