Using the rat vascular smooth muscle cell line A7r5, we found that an hypoxic atmosphere caused a characteristic time-dependent five-to 12-fold up-regulation of the mRNAs of the two P4h alpha-subunits [alphaI (P4ha1) and alphaII (P4ha2)] and of two lysylhydroxylases (PLOD1 and PLOD2). These effects of hypoxia were mimicked by the iron-chelator deferoxamine (100 micro m) and by cobaltous chloride (100 micro m). The hypoxic induction of these genes was also seen in the mouse juxtaglomerular As4.1 cell line and mouse hepatoma cell line Hepa1 but was almost absent in the mutant cell line Hepa1C4, which is defective for the hypoxia-inducible transcription factor 1 (HIF-1). In addition, the enzyme expression was induced by hypoxia in mouse embryonic fibroblasts but not in embryonic fibroblasts lacking the HIF-1alpha subunit. These findings indicate that hypoxia stimulates the gene expression of a cluster of hydroxylases that are indispensible for collagen fiber formation. Strong indirect evidence, moreover, suggests that the expression of these enzymes during hypoxia is coordinated by HIF-1."xsd:string |
