Oxidative stress response of Inonotus obliquus induced by hydrogen peroxide.
While the medicinal fungus Inonotus obliquus produces polyphenols as one of its main metabolites in natural habitats, it accumulates less polyphenols under laboratory conditions. In this study we found that the continuous addition of 1 mM H(2)O(2) at a rate of 1.6 ml/h into a submerged culture of the fungus enhanced its production of mycelia, melanins, flavonoids and hispidin analogs (HA). Simu...
متن کاملAn investigation of the response of lymphoblastoid cells to hydrogen peroxide-derived oxidative stress.
The synthesis of heat shock proteins (HSPs) may play a significant role in the mechanism of cellular protection against oxidative injury [ I , 21. We have shown that T-lymphoid (Molt-3) cells exhibit enhanced susceptibility to H202-induced cytogenetic damage and that these cells also have low levels of intracellular catalase activity [3]. The aim of this study was to investigate the response of...
متن کاملProgesterone and Cilostazol Protect mice pancreatic islets from oxidative stress induced by hydrogen peroxide
Abstract Reactive oxygen species and oxidative stress impair β-cell function and reduce insulin secretion. It has been shown that progesterone and cilostazol possess antioxidant properties. The present study was aimed to investigate in vitro pretreatment effect of progesterone and cilostazol on insulin secretion as well as their protective effects against hydrogen peroxide-induced oxidative str...
متن کاملThe yeast Snt2 protein coordinates the transcriptional response to hydrogen peroxide-mediated oxidative stress.
Regulation of gene expression is a vital part of the cellular stress response, yet the full set of proteins that orchestrate this regulation remains unknown. Snt2 is a Saccharomyces cerevisiae protein whose function has not been well characterized that was recently shown to associate with Ecm5 and the Rpd3 deacetylase. Here, we confirm that Snt2, Ecm5, and Rpd3 physically associate. We then dem...
