Core Tip

Core Tip:Helicobacter pylori (H. pylori) is the most significant risk factor for gastric cancer. Studies have shown that hypoxia-inducible factor-1α (HIF-1α) is highly expressed in tumors, enabling them to adapt to hypoxic microenvironment and promoting malignant behavior. However, the pathogenesis of HIF-1α in H. pylori infection remains unclear. We found that methyltransferase-like protein 14 acts as a molecular switch of H. pylori-induced HIF-1α expression and regulates the malignant behavior of gastric epithelial cells through the PI3K/AKT pathway. This study is the first to explore the mechanism by which H. pylori induces HIF-1α expression from the perspective of N6-methyladenosine modification.
