| abstractText | Infection with Helicobacter pylori (H. pylori) is the main risk factor for gastric cancer, a leading cause of cancer-related death worldwide. The oncogenic functions of cyclin-dependent kinase 1 (CDK1) are not fully understood in gastric tumorigenesis. Using public datasets, quantitative real-time PCR, western blot, and immunohistochemical (IHC) analyses, we detect high levels of CDK1 in human and mouse gastric tumors. H. pylori infection induces activation of nuclear factor kappaB (NF-kappaB) with a significant increase in CDK1 in in vitro and in vivo models (p < 0.01). We confirm active NF-kappaB binding sites on the CDK1 promoter sequence. CDK1 phosphorylates and inhibits GSK-3beta activity through direct binding with subsequent accumulation and activation of beta-catenin. CDK1 silencing or pharmacologic inhibition reverses these effects and impairs tumor organoids and spheroid formation. IHC analysis demonstrates a positive correlation between CDK1 and beta-catenin. The results demonstrate a mechanistic link between infection, inflammation, and gastric tumorigenesis where CDK1 plays a critical role. |
