Hypoxia-inducible PRMT2 addiction in cancers


ABSTRACT: Hypoxia-inducible transcription factors (HIFs) are crucial transcription factors for cellular response to low oxygen levels, but the key mediators for their downstream transcription activation are not well characterized. We previously found that PRMT2 activates target gene expression through its methyltransferase activity on histone H3R8. Here we find that PRMT2 expression is activated by HIF1 at hypoxic conditions. And PRMT2 activity is widely required for hypoxia-induced transcription activation. Accordingly, PRMT2 inactivation alleviates hypoxia-induced glioblastoma progression and chemotherapeutic resistance. And PRMT2 expression is associated with hypoxia signature
