عدم موفقیت در لانه گزینی یکی از مراحل اصلی محدود کننده روش لقاح مصنوعی است. لانه گزینی نتیجه اثر متقابل بین جنین و آندومتر رحم است. شرایط محیطی آندومتر رحم می تواند لانه گزینی جنین راتسهیل کند و یا مانع لانه گزینی جنین شود. عدم تعادل بین رادیکال های آزاد و آنتی اکسیدان های می تواند منجر به نقص آندومتر در نگهداری جنین شود. پلی مورفیسم های ژنتیکی آنزیمهای سم زدا، مانند گلوتاتیون s- ترانسفرازها (g...

Two new Delta and Sigma glutathione S-transferases (GSTs) in the Hessian fly, Mayetiola destructor (Diptera: Cecidomyiidae), were characterized and transcription profiles described. The deduced amino acid sequences for the two M. destructor Delta GSTs (MdesGST-1 and MdesGST-3) showed high similarity with other insect Delta GSTs including the conserved catalytic serine residue. The deduced amino...

Negative cooperativity in enzyme reactions, in which the first event makes subsequent events less favorable, is sometimes well understood at the molecular level, but its physiological role has often been obscure. Negative cooperativity occurs in human glutathione transferase (GST) GSTP1-1 when it binds and neutralizes a toxic nitric oxide adduct, the dinitrosyl-diglutathionyl iron complex (DNDG...

Hookworm glutathione S-transferases (GSTs) are critical for parasite blood feeding and survival and represent potential targets for vaccination. Three cDNAs, each encoding a full-length GST protein from the human hookworm Necator americanus (and designated Na-GST-1, Na-GST-2, and Na-GST-3, respectively) were isolated from cDNA based on their sequence similarity to Ac-GST-1, a GST from the dog h...

Human glutathione transferases (GSTs) are a multigene family of enzymes that are involved in the metabolism of a wide range of electrophilic compounds of both exogenous and endogenous origin. GSTs are generally recognized as detoxifying enzymes by catalyzing the conjugation of these compounds with glutathione, but they may also be involved in activation of some carcinogens. The memmalian GSTs c...

BACKGROUND Glutathione S-transferases (GSTs) metabolize drugs and xenobiotics. Yet despite high protein sequence homology, expression of π-class GSTs, the most abundant of the enzymes, varies significantly between species. In mouse liver, hepatocytes exhibit high mGstp expression, while in human liver, hepatocytes contain little or no hGSTP1 mRNA or hGSTP1 protein. π-class GSTs are known to be ...

Background and purpose: Infection caused by hepatitis B virus is a major health problem and the most common known chronic infection. It has an important role in developing cirrhosis and hepatic cancer. Glutathione-s-transferase enzyme is one of the most important metabolic enzymes in cellular protection mechanisms such as: xenobiotic detoxification and metabolism and cells protection again...

The present study was aimed to analyse the effect of acrylamide and Hybanthus enneaspermus leaf extract active principles on mice testis glutathione-s-transferases (GST; EC 2.5.1.18). These enzymes play a role in biotransformation of electrophilic compounds that cause damage to cells by conjugating with the substrate glutathione. Hybanthus enneaspermus, a spade flower, is an erect shrub of viol...
