Opis:
Male reproductive organs are extremely sensitive to the negative influence of toxic environmental factors as well as drugs, and until now not many attempts have been made at studying the detoxication enzymes and the relationship between the activity of those enzymes and spermatozoa fertility. In the present work we studied cytosolic glutathione-S-transferases (GST, EC 2.5.1.18) from different parts (head, corpus and tail) of bull and boar epididymis. We isolated two molecular forms of GST from each part of epididymis, characterized their biochemical properties and examined the mechanism of the catalyzed reaction. On the basis of their substrate specificity and isoelectric point, the isoforms were found to belong to the near neutral GST class mi. All examined GST forms exhibited higher affinity towards GSH than towards 1-chloro-2,4-dinitrobenzene (CDNB) and bull epididymis GST forms showed biphasic Lineweaver-Burk double reciprocal curves in the presence of GSH as a variable substrate. Boar epididymis anionic GST had the -SH groups both in the GSH and the CDNB binding place, whereas the cationic GST form - arginine residues in the CDNB binding place. Bull epididymis GST forms contained neither thiol nor arginine residues essential for catalytic activity.

glutathione S-transferase pi
Opis:
GST pi, the main glutathione S-transferase isoform present in the human brain, was isolated from various regions of the brain and the in vitro effect of tricyclic antidepressants on its activity was studied. The results indicated that amitripyline and doxepin - derivatives of dibenzcycloheptadiene, as well as imipramine and clomipramine - derivatives of dibenzazepine, inhibit the activity of GST pi from frontal and parietal cortex, hippocampus and brain stem. All these tricyclics are noncompetitive inhibitors of the enzyme with respect to reduced glutathione and noncompetitive (amitripyline, doxepin) or uncompetitive (imipramine, clomipramine) with respect to the electrophilic substrate. Their inhibitory effect is reversible and it depends on the chemical structure of the tricyclic antidepressants rather than on the brain localization of the enzyme. We conclude that the interaction between GST pi and the drugs may reduce their availability in the brain and thus affect their therapeutic activity. On the other hand, tricyclic antidepressants may decrease the efficiency of the enzymatic barrier formed by GST and increase the exposure of brain to toxic electrophiles. Reactive electrophiles not inactivated by GST may contribute in adverse effects caused by these drugs.

Opis:
We investigated the effect of daunorubicin on glutathione content and activity of GSH-related enzymes in cultured normal and diabetic human fibroblasts. Cells were incubated with 4 μM daunorubicin (DNR) for 2 h followed by culture in drug-free medium for up to 72 h. Treatment of diabetic cells with the drug caused a time-dependent depletion of intracellular GSH and a decrease of the GSH to total glutathione ratio. GSH depletion was accompanied by apoptotic changes in morphology of the nucleus. Analysis of GSH-related enzymes showed a significant increase of the activities of Se-dependent and Se-independent peroxidases and glutathione S-transferase. In contrast, glutathione reductase activity was reduced by 50%. Significant differences between normal and diabetic cells exposed to DNR were observed in the level of GST and Se-dependent glutathione peroxidase activities. These findings indicated that daunorubicin efficiently affects the GSH antioxidant defense system both in normal and diabetic fibroblasts leading to disturbances in glutathione content as well as in the activity of GSH-related enzymes.

Opis:
We investigated glutathione level, activities of selenium independent GSH peroxidase, selenium dependent GSH peroxidase, GSH S-transferase, GSH reductase and the rate of lipid peroxidation expressed as the level of malondialdehyde in liver tissues obtained from patients diagnosed with cirrhosis or hepatocellular carcinoma. GSH level was found to be lower in malignant tissues compared to adjacent normal tissues and it was higher in cancer than in cirrhotic tissue. Non-Se-GSH-Px activity was lower in cancer tissue compared with adjacent normal liver or cirrhotic tissue, while Se-GSH-Px activity in cancer was found to be similar to its activity in cirrhotic tissue and lower compared to control tissue. An increase in GST activity was observed in cirrhotic tissue compared with cancer tissue, whereas the GST activity in cancer was lower than in adjacent normal tissue. The activity of GSH-R was similar in cirrhotic and cancer tissues, but higher in cancer tissue compared to control liver tissue. An increased level of MDA was found in cancer tissue in comparison with control tissue, besides its level was higher in cancer tissue than in cirrhotic tissue. Our results show that the antioxidant system of cirrhosis and hepatocellular carcinoma is severely impaired. This is associated with changes of glutathione level and activities of GSH-dependent enzymes in liver tissue. GSH and enzymes cooperating with it are important factors in the process of liver diseases development.

Opis:
Glutathione-S-transferase (GST) a Phase-II drug detoxification enzyme, was detected in Setaria cervi, a bovine filarial parasite. In vitro effect of diethylcarbamazine, butylated hydroxyanisole and phenobarbitone on the GST of adult female S. cervi was assayed by the addition of these compounds in the maintenance medium. The specific activity of GST towards 1-chloro-2,4-dinitrobenzene was increased progressively 1.2-1.97, 1.3-2.4 and 1.2-2.7 times at 10-100 µM of diethylcarbamazine, butylated hydroxyanisole and phenobarbitone, respectively, after 5 h at 37°C. Substrate specificity studies showed a higher increase in specific activity with ethacrynic acid and no change with cumene hydroperoxide. Although the intensity of GST activity band was more in extract from diethylcarbamazine or butylated hydroxyanisole treated worms extract, an extra band of activity appeared in those worm extracts compared to control worm extract. SDS/PAGE showed increased thickness of the band corresponding to purified GST in extracts from diethylcarbamazine/butylated hydroxyanisole/phenobarbitone treated worms. Purification and quantification of GST from diethylcarbamazine and butylated hydroxyanisole treated worms indicated an increase in enzyme specific activity. The increase in GST protein by these agents was blocked by prior treatment with actinomycin D, indicative of a transcription dependent response. The role of this enzyme in motility and viability of microfilariae and adult female was tested in vitro using a range of known GST inhibitors. Of those tested, ethacrynic acid, ellagic acid, 1-chloro-2,4-dinitrobenzene, cibacron blue and butylated hydroxyanisole reduced the viability and motility of microfilariae and adult female worms at micromolar concentrations. These results suggest that S. cervi GST is inducible in response to the antifilarial drug diethylcarbamazine and may play an important role in parasite's survival, thus could be a potential drug target.

Opis:
Human glutathione S-transferase omega 1-1 (hGSTO1-1) is a newly identified member of the glutathione S-transferase (GST) family of genes, which also contains alpha, mu, pi, sigma, theta, and zeta members. hGSTO1-1 catalyzes the reduction of arsenate, monomethylarsenate (MMA(V)), and dimethylarsenate (DMA(V)) and exhibits thioltransferase and dehydroascorbate reductase activities. Recent evidence has show that cytokine release inhibitory drugs, which specifically inhibit interleukin-1b (IL-1b), directly target hGSTO1-1. We found that (+)-α-tocopherol phosphate and (+)-α-tocopherol succinate inhibit hGSTO1-1 in a concentration-dependent manner with IC50 values of 2 µM and 4 µM, respectively. A Lineweaver-Burk plot demonstrated the uncompetitive nature of this inhibition. The molecular mechanism behind the inhibition of hGSTO1-1 by α-tocopherol esters (vitamin E) is important for understanding neurodegenerative diseases, which are also influenced by vitamin E.

Opis:
Changes in blood leucocyte levels were investigated in Spraque-Dowley rats vaccinated with cDNA or protein of glutathione S-transferase (GST) of F. hepatica and subsequently challenged with metacercariae of the liver fluke. The analysis of the leucocyte responses measured in vaccinated rats suggests that the form of antigen used for vaccination intluenced dynamics of white blood cell response to the fluke infection. The most clear differences were observed in neutrophil and eosinophil levels. The weakest reaction of these cells to the challenge infection was observed in rats vaccinated twice with cDNA. In contrast, in rats which received the first antigen dose as cDNA and the second vaccination with GST protein, both neutrophil and eosinophil responses were much higher, especially at 5 and 9 WAI.

Opis:
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 of 4-HNE in stress mediated signaling for apoptosis are critically evaluated. Evidence demonstrating the modulation of UV, oxidative stress, and chemical stress mediated apoptosis by blocking lipid peroxidation by the α-class glutathione S-transferases (GSTs) is presented which suggest an important role of these enzymes in protection against oxidative stress and a role of lipid peroxidation products in stress mediated signaling. Overexpression of 4-HNE metabolizing GSTs (mGSTA4-4, hGSTA4-4, or hGST5.8) protects cells against 4-HNE, oxidative stress (H2O2 or xanthine/xanthine oxidase), and UV-A mediated apoptosis by blocking JNK and caspase activation suggesting a role of 4-HNE in the mechanisms of apoptosis caused by these stress factors. The intracellular concentration of 4-HNE appears to be crucial for the nature of cell cycle signaling and may be a determinant for the signaling for differentiation, proliferation, transformation, or apoptosis. The intracellular concentrations of 4-HNE are regulated through a coordinated action of GSTs (GSTA4-4 and hGST5.8) which conjugate 4-HNE to GSH to form the conjugate (GS-HNE) and the transporter 76 kDa Ral-binding GTPase activating protein (RLIP76), which catalyze ATP-dependent transport of GS-HNE. A mild stress caused by heat, UV-A, or H2O2 with no apparent effect on the cells in culture causes a rapid, transient induction of hGST5.8 and RLIP76. These stress preconditioned cells acquire ability to metabolize and exclude 4-HNE at an accelerated pace and acquire relative resistance to apoptosis by UV and oxidative stress as compared to unconditioned control cells. This resistance of stress preconditioned cells can be abrogated by coating the cells with anti-RLIP76 antibodies which block the transport of GS-HNE. These studies and previous reports discussed in this article strongly suggest a key role of 4-HNE in stress mediated signaling.

Opis:
The role of glutathione-S-transferase (GST, EC 2.5.1.18) in biochemical host defence in experimental trichinellosis was evaluated. The activity of GST in mouse skeletal muscles was measured during the muscular phase of trichinellosis, starting from the 3rd week post infection (w.p.i.) to the 11th w.p.i. Activity was determined spectrophotometrically by monitoring the formation of thioether (S-2,4-dinitrophenylglutathione) from the reduced form of glutathione and 1-chloro-2,4-dinitrobenzene used as a substrate and as an example of xenobiotics. The changes in the activity of GST were as follows: an increase in activity starts in the 4th w.p.i., peaks (up to 310% of the normal value) in the 6th w.p.i., decreases in the 8th week and a final, weak rise was observed in week 11. The statistically significant changes in GST activity in this phase of experimental trichinellosis suggest that this enzyme participates in the biochemical defence of the host against Trichinella infection.

Opis:
Water is a renewable resource. However, with the human population growth, economic development and improved living standards, the world’s supply of fresh water is steadily decreasing and consequently water resources for agricultural production are limited and diminishing. Water deficiency is a significant problem in agriculture and increasing efforts are currently being made to understand plant tolerance mechanisms and to develop new tools (especially molecular) that could underpin plant breeding and cultivation. However, the biochemical and molecular mechanisms of plant water deficit tolerance are not fully understood, and the data available is incomplete. Here, we review the significance of glutathione and its related enzymes in plant responses to drought. Firstly, the roles of reduced glutathione and reduced/ oxidized glutathione ratio, are discussed, followed by an extensive discussion of glutathione related enzymes, which play an important role in plant responses to drought. Special attention is given to the S-glutathionylation of proteins, which is involved in cell metabolism regulation and redox signaling in photosynthetic organisms subjected to abiotic stress. The review concludes with a brief overview of future perspectives for the involvement of glutathione and related enzymes in drought stress responses.

The effects of long-term administration of a standardised extract of Curcuma longa on the explorative activity in aged 24-month-old male Wistar rats were estimated in a hole-board test. The animals received the extract orally for two months in rodent chow at doses of 10 and 50 mg/kg/day. The correlations between concentration of some neurotransmitters and amino acids in selected brain regions, as well as the level of corticosterone in plasma (described previously), and the parameters of exploration were calculated. The antioxidant processes (GSH, GST, CAT and MDA levels) in heart and skeletal muscles were also investigated. The results suggested that the explorative activity of plant extract-treated rats was enhanced; however, no correlations between brain neurotransmitter concentration or plasma corticosterone level and the parameters of explorative activity were observed. In biochemical investigation, chronic C. longa extract administration influenced antioxidant processes (CAT, GST and MDA levels) in skeletal muscles of aged rats, but not in the heart muscle.

Opis:
Cherries contain significant amounts of important nutrients and bioactive food components including fibre, polyphenols, carotenoids, vitamin C, potassium. They are also good source of tryptophan, serotonin, and melatonin. Beside the fact that cherries are considered as an excellent source of numerous nutrients and they also present a low caloric content. These facts lead to their increasing popularity in the human diet. Numerous studies suggest that their regular consumption has a positive effect on health and the well-being of individuals. Another bioactive food components found in cherries are enzymes. The interest in research about enzymes in cherries is not so significant as for other compounds like polyphenols or vitamins. However, number of studies were carried out to characterise enzymes and their function in cherries especially with relation to extending their shelf life. The aim of this work is to give a brief overview of latest research on browning enzymes, softening enzymes and glutathione S-transferase.
