Maintaining a balanced redox state within cells is crucial for the sustenance of life. The process involves continuous cytosolic disulfide reduction reactions to restore oxidized proteins their reduced thiol forms. There are two main cellular antioxidant pathways—the thioredoxin (Trx) and glutathione (GSH)/glutaredoxin (Grx) systems. In GSH/Grx system, reductase (GR; GSR) catalyses GSH (GSSG) its sulfhydryl form (GSH), which can then further reduce Grxs. GR an essential enzyme that helps in...

Notch signaling pathway is activated dynamically during evolution playing significant role in cell fate determination and differentiation. It has been known that alterations of this may lead to human malignancies, including gastric cancer. Despite a decline the overall incidence, disease still remains an important global health problem. Therefore, better understanding molecular underlying cancer contribute development rationally designed targeted therapies. reported Notch1 receptor could...

Glutathione peroxidase 2 (Gpx-2) is a selenoenzyme with antioxidant capabilities that may play role in cancer development. Hence, we investigated the immunohistochemical expression of Gpx-2 protein colon adenocarcinoma samples derived from patients who did not receive any form treatment prior to surgical procedure. The associations between and clinical parameters were analysed using Chi2 test Fisher's exact test. A Kaplan-Meier analysis log-rank used verify relationship intensity 5-year...

Glutaredoxin 2 (Grx2; Glrx2) is a glutathione-dependent oxidoreductase located in mitochondria, which central to the regulation of glutathione homeostasis and mitochondrial redox, plays crucial role highly metabolic tissues. In response redox signals oxidative stress, Grx2 can catalyze oxidation S-glutathionylation membrane-bound thiol proteins mitochondria. Therefore, it have significant impact on cancer development. To investigate this further, we performed an immunohistochemical analysis...

Glutaredoxin 1 (Grx1) is an essential enzyme that regulates redox signal transduction and repairs protein oxidation by reversing S-glutathionylation, oxidative modification of cysteine residues. Grx1 removes glutathione from proteins to restore their reduced state (protein-SH) regulate protein-SSG levels in signaling networks. Thus, it can exert influence on the development cancer. To further investigate this problem, we performed analysis expression colon adenocarcinoma samples Polish...

Water-soluble polymer-drug conjugates were obtained and analyzed towards their potential use as prodrugs for two hydrophobic antipsoriatic agents, including methotrexate (MTX) acitretin (AC). The conjugation efficacy of MTX decreased with a decreasing molar ratio N,N-dimethylaminoethyl methacrylate (DMAEMA) repeating units in the polymethacrylic chains. Cytotoxicity positively charged (from +5 to +10 mV) nano- microparticles (3-1500 nm DMEM at 37 °C) estimated by vitro MTT Annexin-V...

Several studies revealed that expression levels of glutathione peroxidase 1 (Gpx-1) can be associated with cancer development, mainly through its role in hydroperoxide scavenging by regulating intracellular reactive oxygen species (ROS) levels. Therefore, our aim was to investigate the Gpx-1 protein a population Polish patients colon adenocarcinoma absence any therapy prior radical surgery. The study carried out using tissue from confirmed histopathological examination. antibody used...

Despite excellent results of bariatric surgery in the treatment type 2 diabetes and weight loss human subjects, some patients do not obtain desired results. One reasons for this is that all follow caloric intake recommendations.The aim study was to investigate effect duodenojejunal omega switch (DJOS) on body weight, glucose tolerance, incretins rats.DJOS SHAM were performed rats maintained 8 weeks high-fat diet (HF) control (CD), respectively. After surgery, four groups kept same as before...

Nutritional status is a major determinant of hepatocyte injuries associated with changed metabolism and oxidative stress. This study aimed to determine the relations between stress, bariatric surgery, high-fat/high-sugar (HFS) diet in diet-induced obesity rat model. Male rats were maintained on control (CD) or inducing obesity. After 8 weeks, animals underwent SHAM (n = 14) DJOS surgery was either unchanged.
