Thioredoxin reductase and glutathione reductase are important enzymes of redox system that help the malaria parasite to maintain an adequate intracellular redox environment and contribute greatly to the antioxidant capacity of the cell. In the present study humoral immune response directed against thioredoxin reductase and glutathione reductase during Plasmodium berghei infection were investiga...

Introduction: Triphala, consisting of three fruits, Phyllanthus emblica L. (Phyllanthaceae), Terminalia bellirica (Gaertn.) Roxb. (Combretaceae), and T. chebula Retz, is a well-recognized Ayurvedic herbal formulation, used for various therapeutic purposes, including the treatment dyslipidemia. Inhibitory activity against 3‑hydroxy‑3‑methylglutaryl‑coenzyme A (HMG‑CoA) reductase, rate-limiting e...

initially high but declined as HMG-CoA reductase became activated. Glucagon prevented the loss of activity, whereas insulin promoted inactivation of the enzyme. Similar affects on the activity of HMG-CoA reductase kinase. and the state of phosphorylation of HMG-CoA reductase in liver have been reported after injection of rats with glucagon (Beg el al., 1979). Thus insulin and glucagon have conc...

Aldose reductase is an NADPH-dependent aldo-keto reductase best known as the rate-limiting enzyme of the polyol pathway that is implicated in the complications of diabetes. Aldose reductase appears to be involved in a variety of disease states other than diabetes, presumably due to its ability to catalyze the reduction of a broad spectrum of aldehydes, including some cytotoxic products of lipid...

Immunoprecipitation of native rat liver microsomal 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, phosphorylated by [gamma-32P]ATP in the presence of reductase kinase, revealed a major 97-kDa 32P band which disappeared upon competition with pure unlabeled 53-kDa HMG-CoA reductase. A linear correlation between the expressed/total HMG-CoA reductase activity ratio (E/T) and the fractio...

background & aim:mentha longifolia (l.) huds is an aromatic perennial herb that belongs to the   family lamiaceae. the aim of this study was to identify chemical composition of aerial parts   (including leaf, stem and flowers) of m. longifolia collected from   (kamu mountain) isfahan province. experimental: the essential oils were extracted   using the hydrodistillation method and analysed by g...

3-Deoxyglucosone reductase activity in the extracts of rat, pig and human livers was potently inhibited by aldehyde reductase inhibitors. The major species of 3-deoxyglucosone reductase purified from human and pig livers were biochemically and immunochemically identical with aldehyde reductase. The two enzymes and rat liver aldehyde reductase exhibited higher catalytic efficiency for 3-deoxyglu...

Protein phosphatase C was purified 1500-fold from rat liver by a six-step procedure including a fractionation step with 80% ethanol at room temperature and two successive chromatographic separations on DEAESephadex. This preparation restored hydrox~ethyl glutaryl-CoA (HMG-CoA) reductase activity in liver microsomes pretreated with MgATP and also inactivated HMG-CoA reductase kinase. The relativ...

A monomeric (Mr = 43,000) NADPH-dependent oxidoreductase with a broad substrate specificity for aliphatic and aromatic aldehydes and aldo sugars has been purified from the skeletal muscle of female and castrated pigs. The properties of this enzyme are consistent with those of aldose reductase (EC 1.1.1.21), and the enzyme is immunologically identical with aldose reductase from pig lens. However...
