Glutathione S-Transferase activities and glutathione levels in needles of drought stressed Pinus Brutia Ten. trees

Aim: Glutathione S-transferases (GST) take roles under stress conditions by the conjugation of Glutathione (GSH) to electrophilic substrates to increase their solubility and facilitating further metabolic processing. This is one of the main pathways functioning in stress resistance and, for dought stress, there is not yet a study on Pinus brutia Ten. which is a very important forest tree of Turkey.


Enantioselective reduction of ketones with borane catalyzed by cyclic β- amino alcohols prepared from proline
Demir, Ayhan S; Mecitoglu, Idris; Tanyeli, Cihangir; Gülbeyaz, Volkan (Elsevier BV, 1996-12)
New catalysts have been prepared from (S)- and (R)- proline and the asymmetric borane reduction of prochiral ketones using these catalysts has been studied. The secondary alcohols were obtained in 76-95% yield with 57-96% enantiomeric excesses. Copyright (C) 1996 Elsevier Science Ltd
Dielectric Properties of Ethanol and Gasoline Mixtures by Terahertz Spectroscopy and an Effective Method for Determination of Ethanol Content of Gasoline
ARIK, Enis; Altan, Hakan; Esentürk, Okan (American Chemical Society (ACS), 2014-05-01)
Investigation of frequency dependent permittivity of mixture solutions provides information on the role of intermolecular interactions on relaxation processes of solvent and solute molecules. In this study the dielectric properties of ethanol/gasoline mixtures in the terahertz spectral region are investigated. Frequency dependent absorption coefficients, refractive indices, and complex permittivities of pure ethanol and gasoline, and their mixtures at varying ethanol volume percentages (v/v %) are reported....
Butyrate mediated regulation of RNA binding proteins in the post-transcriptional regulation of inflammatory gene expression
Torun, Aydan; Enayat, Shabnam; Sheraj, Ilir; Tuncer, Sinem; Ulgen, Dogukan Hazar; Banerjee, Sreeparna (Elsevier BV, 2019-12-01)
Short chain fatty acids (SCFAs) are produced by commensal bacteria in the gut and are known to reduce inflammation through transcriptional inhibition of cytokines and inflammatory proteins such as cyclooxygenase-2 (COX-2). Butyrate is a SCFA that was reported to alter the mRNA stability of inflammatory genes by increasiing the expression of the RNA binding protein (RBP) Tristetraprolin (TTP). We have hypothesized that butyrate may regulate gene expression post-transcriptionally through global effects on the...
Association analysis of Glutathione S-transferase omega-1 and omega-2 genetic polymorphisms and ischemic stroke risk in a Turkish population

Objectives: Oxidative stress is a known risk factor for the pathogenesis of atherosclerosis, the main cause of ischemic stroke. Glutathione S-transferase (GST) omega-1 and omega-2, members of phase II enzymes, play a role in the antioxidant system. The single nucleotide polymorphisms (SNPs), C419A and A424G in GST omega genes can cause a decrease in enzyme activity. The aim of this study was to investigate the possible association between these polymorphisms and ischemic stroke risk in a Turkish population.
Gene expressions of Mn-SOD and GPx-1 in streptozotocin-induced diabetes: effect of antioxidants
Sadi, Goekhan; Güray, Nülüfer Tülün (Springer Science and Business Media LLC, 2009-07-01)
Increased oxidative stress and impaired antioxidant defense mechanisms are believed to be the important factors contributing to the pathogenesis and progression of diabetes mellitus. In this study, we have reported the effects of the streptozotocin-induced diabetes on the gene expression and the activities of two antioxidant enzymes, manganese superoxide dismutase (MnSOD) and glutathione peroxidase (GPx). We also studied the effects of two antioxidants, vitamin C and DL-alpha-lipoic acid (LA), on the system...
