Gamma-glutamyltransferase, H2O2-induced apoptosis and expression of catalase.

Dear Editor: We would like to call the attention of the readers on a biochemical aspect generating occasional disputes in studies concerned with oxidative stress-related apoptosis. The paper recently published in this journal by Moon et al. (2012) documents that the mutation of K-RAS in prostate epithelial cells causes the activation of the ERK signalling pathway and an increased expression of ...

Resveratrol protects human lens epithelial cells against H2O2-induced oxidative stress by increasing catalase, SOD-1, and HO-1 expression

PURPOSE Oxidative damage induced by H(2)O(2) treatment can irreversibly damage the lens epithelium, resulting in cell death and cataract. Whether the effects of oxidative stress could be attenuated in cultured human lens epithelial cells by incubation with resveratrol (RES) is still unknown. In the present study, we examined the function of resveratrol in protecting human lens epithelial B-3 (H...

Gene transcriptomic profile in arabidopsis thaliana mediated by radiation-induced bystander effects

Background: The in vivo radiation-induced bystander effects (RIBE) at the developmental, genetic, and epigenetic levels have been well demonstrated using model plant Arabidopsis thaliana (A. thaliana). However, the mechanisms underlying RIBE in plants are not clear, especially lacking a comprehensive knowledge about the genes and biological pathways involved in the RIBE in plants. Materials and...

Drought controls on H2O2 accumulation, catalase (CAT) activity and CAT gene expression in wheat.

Plants co-ordinate information derived from many diverse external and internal signals to ensure appropriate control of gene expression under optimal and stress conditions. In this work, the relationships between catalase (CAT) and H2O2 during drought in wheat (Triticum aestivum L.) are studied. Drought-induced H2O2 accumulation correlated with decreases in soil water content and CO2 assimilati...

Phagocytosis and H2O2 induce catalase and metallothionein gene expression in human retinal pigment epithelial cells.

PURPOSE Reactive oxygen intermediates have been implicated in the aging process and degenerative diseases of the eye, including retinopathy of prematurity, cataractogenesis, and macular degeneration. The purpose of this study was to investigate the effect of phagocytosis of photoreceptor outer segments and the addition of exogenous H2O2 on catalase and metallothionein expression in human retina...
