We herein show that TP is highly induced by serum deprivation in NPC cells, and that this is due to an increase in the half-life of the TP mRNA, as shown by nuclear run-on and actinomycin D assays. We further show that the CU-rich element of the TP mRNA directly interacts with hnRNP K, as demonstrated by immunoprecipitation RT-PCR assays, and the nucleus-to-cytoplasm translocation of hnRNP K. Blockade of hnRNP K expression reduces TP expression, suggesting that hnRNP K acts in the upregulation of TP. Mechanistically, both MEK inhibitor and the hnRNP K ERK-phosphoacceptor-site mutant decrease cytoplasmic accumulation of hnRNP K, suggesting that ERK-dependent phosphorylation is critical for TP induction. Furthermore, we found that hnRNP K-mediated TP induction allows NPC cells to resist hypoxia-induced apoptosis. Our results collectively establish the regulation and role of ERK-mediated cytoplasmic accumulation of hnRNP K as an upstream modulator of TP, suggesting that hnRNP K may be an attractive candidate as a future therapeutic target for cancer."xsd:string |
