Glutathione peroxidase 2

GPX2, GPRP, gastrointestinal glutathione peroxidase, glutathione peroxidase 2, GI-GPx
This gene is a member of the glutathione peroxidase family and encodes a selenium-dependent glutathione peroxidase that is one of two isoenzymes responsible for the majority of the glutathione-dependent hydrogen peroxide-reducing activity in the epithelium of the gastrointestinal tract. The protein encoded by this locus contains a selenocysteine (Sec) residue encoded by the UGA codon, which normally signals translation termination. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2012] (from NCBI)

Gene-specific regulation of hepatic selenoprotein expression by interleukin-6.
Schomburg et al., Berlin, Germany. In Metallomics, Dec 2015
The effects of IL-6 on glutathione peroxidase (GPX) expression were isozyme-specific; GPX1 remained unaffected, while transcript concentrations of GPX2 increased and those of GPX4 decreased.

Glutathione peroxidases.
Maiorino et al., Germany. In Biochim Biophys Acta, 2013
MAJOR CONCLUSIONS: GPxs are involved in balancing the H2O2 homeostasis in signalling cascades, e.g. in the insulin signalling pathway by GPx1; GPx2 plays a dual role in carcinogenesis depending on the mode of initiation and cancer stage; GPx3 is membrane associated possibly explaining a peroxidatic function despite low plasma concentrations of GSH; GPx4 has novel roles in the regulation of apoptosis and, together with GPx5, in male fertility.

Based on this review it may be concluded that an understanding of the impact of ITC and Se on aberrant DNA methylation in relation to factors modulating gene-specific and global methylation patterns, in addition to the effect of these food constituents as modulators of key selenoenzymes, such as gastrointestinal glutathione peroxidase-2 (GPx2) and thioredoxin reductase-1 (TrxR1), may provide insights into the potential synergy among various components of a plant-based diet that may counteract the genetic and epigenetic alterations that initiate and sustain neoplasia.
