OBJECTIVE Glutathione-S-transferase (GST) subtype α and π are differentially expressed in adult liver tissue. Objective of the study was if GST α and π may serve as predictive markers for liver surgery, especially transplantations. METHODS 13 patients receiving living donor liver transplantation (LDLT) and their corresponding donors were analyzed for standard serum parameters (ALT, AST, γGT, ...

Capsomers were produced in bacteria as glutathione-S-transferase (GST) fusion proteins with human papillomavirus type 16 L1 lacking the first nine and final 29 residues (GST-HPV16L1Δ) alone or linked with residues 13-47 of HPV18, HPV31 and HPV45 L2 in tandem (GST-HPV16L1Δ-L2x3). Subcutaneous immunization of mice with GST-HPV16L1Δ or GST-HPV16L1Δ-L2x3 in alum and monophosphoryl lipid A induced s...

Leukocyte 8-hydroxy-2'-deoxyguanosine (8-OHdG) is a surrogate marker of oxidant-induced DNA damage in patients undergoing maintenance hemodialysis (MHD). Glutathione S-transferase M1 (GST M1) is a member of the GST family of proteins, which protect cellular DNA against oxidative damage. This study tested the association of a common GST M1 gene polymorphism [GST M1(-)], known to produce a dysfun...

The human glutathione transferases (GSTs) are a multigene family of detoxication enzymes with patterns of expression that are both tissue specific and genetically determined. Changes in the levels of one or more GST isoenzymes have been associated with the development of anticancer drug resistance in cultured cell lines. In this study, total GST activity and GST isoenzyme composition have been ...

The failure of the Ge2Sb2Te5 (GST) phase change memory cell has been investigated by the High Resolution Transmission Electron Microscopy (HR-TEM). The HR-TEM results indicate that the both of hexagonal structured GeSbTe (GST) and meta stable GeTe phases are appeared after about 10 cycles of set/reset operations. The face centered cubic structured GST seems to be quickly changed from amorphous ...

Dipteran-specific insecticidal protein Cry4A is produced as a protoxin of 130 kDa in Bacillus thuringiensis subsp. israelensis. Here we performed the in vitro processing of Cry4A and showed that the 130-kDa protoxin of Cry4A was processed into the two protease-resistant fragments of 20 and 45 kDa through the intramolecular cleavage of a 60-kDa intermediate. The processing into these two fragmen...

The glutathione S-transferase (GST)-pi gene is overexpressed in many human cancers and preneoplastic lesions and is associated with failure of cancer chemotherapy and poor patient survival. Although GST-pi overexpression in tumors of the central nervous system has been observed, the prognostic and/or clinical relevance of this overexpression has, to date, not been investigated. In this study, w...

background cellular level of enzyme activity can serve as a reliable biomarker in the event of environmental/chemical insults. objectives the present study investigated time-dependent alterations of erythrocyte glutathione s-transferase (ery-gst) activity of non-malarious guinea pigs (cavia tschudii) administered with pyrimethamine/sulfadoxine and artemether/lumefantrine combination therapies. ...

In mouse lung, glutathione S-transferase (GST, EC 2.5.1.18) isoenzymes belonging to the three major known classes, Alpha, Mu and Pi, have been previously characterized, along with an isoenzyme (pI 5.7) that could not be identified with the Alpha, Mu or Pi classes of GSTs. In the present studies we have demonstrated that this isoenzyme is also expressed in liver. Its structural, kinetic, and imm...
