Interactions between odorants and glutathione transferases in the human olfactory cleft

2020

AbstractXenobiotic metabolizing enzymes and other proteins, including odorant-binding proteins located in the nasal epithelium and mucus, participate in a series of processes modulating the concentration of odorants in the environment of olfactory receptors (ORs) and finely impact odor perception. These enzymes and transporters are thought to participate in odorant degradation or transport. Odorant biotransformation results in 1) changes in the odorant quantity up to their clearance and the termination of signaling and 2) the formation of new odorant stimuli (metabolites). Enzymes, such as cytochrome P450 and glutathione transferases (GSTs), have been proposed to participate in odorant clea…

OBJECTIVE: Cellular detoxification mechanisms are mandatory for cellular protection against oxidative stress and reactive oxygen species. One major group of antioxidative active enzymes involved in cellular detoxification are the Glutathione S-Transferases (GST). Multiple subtypes like GSTM1, GSTP1, and GSTT1 and variants of them are known, arising from allelic variations of the GST loci. Moreover, functional variants occur in high percentages and have been associated with diseases like bronchial asthma and bronchial hyperresponsiveness. The interplay of oxidative stress, detoxifying genes like GSTs and the genesis of respiratory tract illness is under contradictory debate. In this study, w…

Introduction: Polymorphisms in certain genes involved on chemo/radio therapy response, as genes involved on DNA synthesis and repair, oxidative stress and drug detoxification, could be related to increased risk of develop t-AML. Objectives: To identified SNPs on genes that could be involved on putative risk of developing t-AML. To analyse the influence of relevant polymorphisms between groups of patients depending of the intensity and the type of treatment received. Material and Methods: Twelve polymorphisms located on genes from drug detoxification pathways (NOQ1, GSTP1), DNA repair (XPC[3], XRCC1[2], NBS1, ERCC5 and XRCC3) and DNA synthesis (MTHFR[2]) were studied. The analysis was carrie…
