Abstract:

Clinical studies demonstrate that cyclin-dependent kinase 4/6 inhibitors exhibit limited efficacy in gastric cancer. Cyclin E1, encoded by CCNE1 gene, contributes to intrinsic resistance to CDK4/6 inhibition in gastric cancer. In this study, we aimed to interrogate the potential application of CDK2/4/6i in gastric cancer. We found that CDK4/6 inhibition showed little to moderate potency in gastric tumor cell lines. In contrast, targeting CDK2/4/6 more potently inhibited cell proliferation and Rb-E2F signaling pathway. Mechanistically, a CDK2/4/6 inhibitor, PF-06873600, exert its effects on promoting cellular senescence via an integrated mechanism of cell cycle arrest and cellular senescence by upregulating nuclear factor kappa B (NF-κB) activity. Moreover, PF- 06873600 effectively inhibited Rb signaling and cell growth in GC cells over expressing CCNE1. Our preclinical data provide scientific rationale for co-targeting CDK2 and CDK4/6 in gastric cancer.
