HNRNPA0 and neoplasm: The phosphorylation of hnRNP A0 was aberrantly induced in cancer cells, and the interaction of hnRNP A0 and mitosis-related RAB3GAP1 mRNA was diminished by the deactivation or deletion of the phosphorylated site of hnRNP A0 (Ser84), suggesting that the dysregulation of RNAs through the abnormal phosphorylation of hnRNP A0 leads to tumor progression and is a novel target for cancer treatment (Fig. 6).
