Lipid peroxidation and cell cycle signaling: 4-hydroxynonenal, a key molecule in stress mediated signaling.
Role of lipid peroxidation products, particularly 4-hydroxynonenal (4-HNE) in cell cycle signaling is becoming increasingly clear. In this article, recent studies suggesting an important role ofExpand
Human glutathione S-transferases.
1. Multiple forms of glutathione S-transferase (GST) isoenzymes present in human tissues are dimers of subunits belonging to three distinct gene families namely alpha, mu and pi. Only the subunitsExpand
Purification and properties of human erythrocyte glutathione peroxidase.
Glutathione peroxidase has been purified to homogeneity from human erythrocytes. The purification steps involved ammonium sulfate precipitation of hemolysate, CM-cellulose (CM-52), DEAE-celluloseExpand
Naturally occurring human glutathione S-transferase GSTP1-1 isoforms with isoleucine and valine in position 104 differ in enzymic properties.
Glutathione S-transferase P1-1 isoforms, differing in a single amino acid residue (Ile104 or Val104), have been previously identified in human placenta [Ahmad, H., Wilson, D. E., Fritz, R. R., Singh,Expand
Physiological role of mGSTA4-4, a glutathione S-transferase metabolizing 4-hydroxynonenal: generation and analysis of mGsta4 null mouse.
The lipid peroxidation product 4-hydroxynon-2-enal (4-HNE) is a strong electrophile that forms covalent adducts with proteins and, to a lesser extent, nucleic acids and phospholipids. The generationExpand
Regulation of 4-hydroxynonenal-mediated signaling by glutathione S-transferases.
4-Hydroxynonenal (HNE), one of the major end products of lipid peroxidation, has been shown to be involved in signal transduction and available evidence suggests that it can affect cell cycle eventsExpand

Allelic forms of hGSTP1-1 which differ from each other by their catalytic properties and, structurally, by the amino acid(s) in position(s) 104 or (and) 113 are known to exist in human populations.Expand
Mechanisms of anticarcinogenic properties of curcumin: the effect of curcumin on glutathione linked detoxification enzymes in rat liver.
Curcumin, an antioxidant isolated from turmeric (curcuma longa), has been shown to attenuate chemical carcinogenesis in rodents. Previous studies have shown that curcumin causes an increase inExpand
Curcumin-glutathione interactions and the role of human glutathione S-transferase P1-1.
Curcumin (diferuloylmethane), a yellow pigment of turmeric with antioxidant properties has been shown to be a cancer preventative in animal studies. It contains two electrophilic alpha,Expand
RLIP76, a non-ABC transporter, and drug resistance in epilepsy
BackgroundPermeability of the blood-brain barrier is one of the factors determining the bioavailability of therapeutic drugs and resistance to chemically different antiepileptic drugs is aExpand
