Protective Effect of Quercetin on Oxidative Stress in Glucose-6-Phosphate Dehydrogenase-Deficient Erythrocytes in Vitro

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

An alternatively spliced form of NQO1 (DT-diaphorase) messenger RNA lacking the putative quinone substrate binding site is present in human normal and tumor tissues.

DT-diaphorase is a ubiquitously expressed flavoenzyme responsible for the two-electron reduction of a number of quinone and other anticancer drugs. The majority of DT-diaphorase enzyme activity in human tissues is the product of the NQO1 gene. We have now identified a novel alternatively spliced form of human NQO1 mRNA lacking exon 4 at levels equal to or exceeding those of wild-type NQO1 mRNA....

Characterization of an intron splice enhancer that regulates alternative splicing of human GH pre-mRNA.

Splicing of pre-mRNA transcripts is regulated by consensus sequences at intron (intervening sequence, IVS) boundaries and the branch site. In vitro studies have shown that the small introns of some genes also require intron splice enhancers (ISE) to modulate splice site selection. An autosomal dominant form of isolated GH deficiency (IGHD-II) is caused by mutations in IVS3 of the GH-1 gene that...
