The novel WD-repeat protein MORG1 acts as a molecular scaffold for HIF prolyl-hydroxylase 3 (PHD3).

'Hypoxia-inducible factor-1 (HIF-1), a transcriptional complex composed of an oxygen-sensitive alpha- and a beta-subunit, plays a pivotal role in cellular adaptation to low oxygen availability. Under normoxia, the alpha-subunit of HIF-1 is hydroxylated by a family of prolyl hydroxylases (PHDs) and consequently targeted for proteasomal degradation. Three different prolyl hydroxylases ...

Nitric oxide-induced cellular stress and p53 activation in chronic inflammation.

PubMed ID:12518062
Free radical-induced cellular stress contributes to cancer during chronic inflammation. Here, we investigated mechanisms of p53 activation by the free radical, NO. NO from donor drugs induced both ataxia-telangiectasia mutated (ATM)- and ataxia-telangiectasia mutated and Rad3-related-dependent p53 posttranslational modifications, leading to an increase in p53 transcriptional targets and a G(2)M ...

Inhibition of the human thioredoxin system. A molecular mechanism of mercury toxicity.
Authors:Carvalho CM, Chew EH, Hashemy SI, Lu J, Holmgren A,
Journal:J Biol Chem
PubMed ID:18321861
Mercury toxicity mediated by different forms of mercury is a major health problem; however, the molecular mechanisms underlying toxicity remain elusive. We analyzed the effects of mercuric chloride (HgCl(2)) and monomethylmercury (MeHg) on the proteins of the mammalian thioredoxin system, thioredoxin reductase (TrxR) and thioredoxin (Trx), and of the glutaredoxin ...

Spermidine but not spermine is essential for hypusine biosynthesis and growth in Saccharomyces cerevisiae: Spermine is converted to spermidine in vivo by the FMS1-amine oxidase.
Authors:Chattopadhyay MK, Tabor CW, Tabor H,
Journal:Proc Natl Acad Sci U S A
PubMed ID:14617780
In our earlier work we showed that either spermidine or spermine could support the growth of spe2Delta or spe3Delta polyamine-requiring mutants, but it was unclear whether the cells had a specific requirement for either of these amines. In the current work, we demonstrate that spermidine is specifically required for the ... More
Heat shock protein-70 expressed on the surface of cancer cells binds parathyroid hormone-related protein in vitro.

Recent studies have shown that the functions of PTH-related protein (PTHrP) and its derived peptides cannot be attributed solely to PTH/PTHrP receptor binding. The present study focused on the identification of other proteins that might bind PTHrP at the cell surface. Using affinity chromatography, we applied extracts of cell-surface biotinylated ... More
