Core Tip
Core Tip: IGF2BP3 is highly expressed in gastric cancer and is closely associated with poor patient prognosis. IGF2BP3 promotes gastric cancer growth and progression both in vivo and in vitro. Mechanistically, IGF2BP3 recognizes and binds to N6-methyladenosine-modified site on FBXO32 messenger RNA, thereby upregulating FBXO32 protein expression. This activates the downstream cyclic guanosine monophosphate-protein kinase G (cGMP-PKG) signaling pathway, thereby regulating multiple biological functions of gastric cancer cells and promoting tumor progression. We propose that targeting of the IGF2BP3/FBXO32/cGMP-PKG axis could represent a promising therapeutic modality for gastric cancer.
