WebMay 14, 2012 · IRP proteins bind with different stabilities to IRE-RNAs of the IRE-RNA family (12, 13), creating a graded or hierarchal set of mRNA responses to iron in vivo. Deletion of … WebTreatment of EC with a nitric oxide donor increases IRP affinity for ferritin mRNA concomitant with a loss of cytoplasmic aconitase activity in iron laden EC. Iron-treated EC exposed to NO donors were resistant to oxidative injury despite their low ferritin content when examined I h after the treatment period. In contrast, 24 h later, these ...

WebMay 14, 2012 · The noncoding IRE-RNA structure, approximately 30 nt, folds into a stem loop to control synthesis of proteins in iron trafficking, cell cycling, and nervous system function. IRE-RNA riboregulators bind specifically to iron-regulatory proteins (IRP) proteins, inhibiting ribosome binding. WebMutations in the L-ferritin IRE that decrease the affinity for IRPs lead to dysregulation of ferritin synthesis. These mutations cause the disease hereditary hyperferritinemia cataract syndrome (HHCS), and the effect on IRP binding affinity correlates with the clinical severity of the disease (Girelli et al. 1995; Allerson et al. 1999 ... can music help the brain
