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...
A haloenol lactone derivative has been synthesized and found to be an isozyme-selective and active site-directed inactivator of glutathione S-transferase (GST). Preincubation of the haloenol lactone (100 microM) with murine Alpha, Mu, or Pi GST isozyme (1.0 microM) at pH 6.5, 37 degrees C resulted in time-dependent loss of enzyme activity with highly selective inhibition of the Pi isozyme (t1/2...
The humoral immune response against an Entamoeba histolytica recombinant protein has been investigated. The 628 bp Bam HI-Eco RI DNA fragment (L1b) from the M11 cDNA clone, partially coding for a 220 kDa (L220) protein, was ligated in-frame into the pGEX-3X plasmid vector to produce the fusion protein GST-L1b. BALB/c mice were immunized with different doses of the GST-L1b fusion protein (10-500...
گلوتاتیون s-ترانسفرازها یک فوق خانواده قدیمی از پروتئین های اتصالی و کاتالیزوری می باشند که در طیف بسیار متنوعی از موجودات هوازی از باکتری ها تا انسان موجود می باشند. این آنزیم ها در گیاهان به هشت کلاس طبقه بندی می شوند که هفت کلاس آن (phi، lambda، theta، zeta، tau، دهیدروآسکوربات ردوکتاز و تتراکلروهیدروکینون دهالوژناز) محلول و یک کلاس آن میکروزومال می باشد. کلاس های tau و phi فراوانترین gst ها...
Glutathione transferase (GST) activity and GST isoenzyme composition have been determined for 24 human neoplasms and 6 human tumor cell lines. Substantial activity (40-1010 milliunits/mg protein) was identified in all tumor specimens examined and three of the tumor cell lines. Three tumor cell lines, the human small cell carcinoma line SW2-10S, the Burkitt's lymphoma derived cell line Raji, and...
گلوتاتیون - s - ترانسفراز سیتوزولی بعنوان یک خانواده آنزیمی است که کنژگاسیون تعداد زیادی از ترکیبات الکتروفیل اگزوژن و اندوژن را با گلوتاتیون کاتالیز می کند. این آنزیم به سه دسته، آلفا، مو و پی تقسیم می شود، که دسته پی بعنوان شاخص در تعدادی از سرطانها، از جمله، کبد، لوسمی، مری، معده، رود بزرگ و ... معرفی شده است ، لذا تشخیص و اندازه گیری این فاکتور در بافت و سرم می تواند در تشخیص سرطان مفید باش...
Glutathione S-transferase (GST) enzyme activity, GST isoenzyme composition and glutathione (GSH) concentration were assessed in normal and squamous cell carcinoma specimens of 14 patients with oral or oropharyngeal cancer and 11 patients with laryngeal cancer. Comparing malignant with normal oral/oropharyngeal tissues, no significant differences in GSH content, GST enzyme activity or isoenzyme ...
OBJECTIVE Oxidative stress may be an important pathogenic mechanism in the obesity and metabolic syndrome. The aims of this study was to assess the possible association between the oxidative stress related Glutathione S-Transferase genes (GST-M1, GST-T1, and GST-P1) variants and the olanzapine-induced weight gain in Korean schizophrenic patients. METHODS We categorized 78 schizophrenic patien...
High-molecular-weight kininogen (HK) and its domain 3 (D3) exhibit anticoagulant properties and inhibit platelet activation at low thrombin concentration in vitro. We hypothesized that the rapid occlusive thrombosis in HK-deficient (HKd) rats following endothelial injury of the aorta results from enhanced platelet aggregation by thrombin. The effects of D3 (G235-M357) or D3-derived peptides on ...
background: normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. the aim of t...
