Gene expression during acute and prolonged hypoxia is regulated by distinct mechanisms of translational control.
Hypoxia has recently been shown to activate the endoplasmic reticulum kinase PERK, leading to phosphorylation of eIF2alpha and inhibition of mRNA translation initiation. Using a quantitative assay, we show that this inhibition exhibits a biphasic response mediated through two distinct pathways. The first occurs rapidly, reaching a maximum at 1-2 h and is due to phosphorylation of eIF2alpha. Con...
متن کاملTranslational control of gene expression and disease.
In the past decade, translational control has been shown to be crucial in the regulation of gene expression. Research in this field has progressed rapidly, revealing new control mechanisms and adding constantly to the list of translationally regulated genes. There is accumulating evidence that translational control plays a primary role in cell-cycle progression and cell differentiation, as well...
متن کاملTranslational control of collagen prolyl 4-hydroxylase-alpha(I) gene expression under hypoxia.
Hypoxia is a pro-fibrotic stimulus, which is associated with enhanced collagen synthesis, as well as with augmented collagen prolyl 4-hydroxylase (C-P4H) activity. C-P4H activity is controlled mainly by regulated expression of the alpha C-P4H subunit. In this study we demonstrate that the increased synthesis of C-P4H-alpha(I) protein in human HT1080 fibroblasts under long term hypoxia (36 h, 1%...
متن کاملTranslational control of photo-induced expression of the Cat2 catalase gene during leaf development in maize.
In dark-grown leaves of Zea mays, the catalase (H2O2:H2O2 oxidoreductase; EC 1.11.1.6; CAT) isozyme CAT-2 is absent. With continuous white light, CAT-2 protein levels increase (due to de novo synthesis) and plateau after 24 hr. When total poly(A)+ RNA (mRNA), polysomes, or isolated polysomal mRNA from light- and dark-treated leaves was translated in vitro, CAT-2 was detected only among the ligh...
متن کاملTranslational control of ceruloplasmin gene expression: beyond the IRE.
Translational control is a common regulatory mechanism for the expression of iron-related proteins. For example, three enzymes involved in erythrocyte development are regulated by three different control mechanisms: globin synthesis is modulated by heme-regulated translational inhibitor, erythroid 5-aminolevulinate synthase translation is inhibited by binding of the iron regulatory protein to t...
