タイトル Cell type-specific reciprocal regulation of HIF1A gene expression is dependent on 5'- and 3'-UTRs.
ジャーナル Biochem Biophys Res Commun
Abstract In the present study, we demonstrated the reciprocal regulation of hypoxia-inducible factor 1 alpha (HIF1A) gene expression via untranslated region-(UTR) dependent mechanisms. A 151 nucleotide sequence found in the HIF1A 5'-UTR is sufficient for significant translational up-regulation. On the other hand, the 3'-UTR of HIF1A has been implicated in mRNA degradation. In the non-metastatic breast cancer cell line MCF7, the 3'-UTR-dependent down-regulatory machinery predominates over the 5'-UTR-dependent up-regulation of HIF1A. However, 5'-UTR-dependent up-regulation is dominant among metastatic cell lines (MDA-MB453, U87MG). It is therefore likely that the predominance of 5'-UTR-dependent translational enhancement of HIF1A is critical for the malignant phenotype of cancer cells. PTBP-1, but not HuR, is a candidate RNA binding protein for the translational control of HIF1A.
