the thioredoxin system, comprising thioredoxin (trx), thioredoxin reductase (trxr) and nadph, is one of the major cellular antioxidant systems, implicated in a large and growing number of biological functions. trx acts as an oxidoreductase via a highly conserved dithiol/disulfide motif located in the active site ( trp-cys-gly-pro- cys-lys-). different factors are involved in the regulation of t...
Introduction: Epigenetic mechanisms regulate expression of the genome to generate various cell types during development or coordinate cellular responses to external stimulus. While epigenetics is of fundamental importance in eukaryotes, it plays a different role in bacteria. This article uncovers the most important recent data on how bacteria can alter epigenetic marks and can also contribute t...
Epigenetics are dynamic and inherited changes in the genome that occur independently of DNA sequencing. This phenomenon requires coherent interaction with various enzymes and other molecular components. Abnormal epigenetic changes can lead to the onset of improper gene expression and the promotion of tumorigenesis. Because epigenetic changes are prone to external and reversible factors, they ar...
Sulfur mustard (SM, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes DNA alkylation, protein modification and membrane damage. SM can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. Epigenetic regulation of gene expression is a growing research topic and is ...
AIM Tricyclic antidepressant (TCA) overdose is generally associated with central nervous system (CNS) and cardiovascular toxicity manifested by seizure, electrocardiographic (ECG) abnormalities and arrhythmia. The objective of this study was to determine whether TCA toxicity would be reduced in patient where benzodiazepine (BDZ) was co-ingested with TCA. DESIGN Patients who were diagnosed to ...
