Science signaling   12(587)    Jun 2019   [Refereed]
Chronic exposure to methylmercury (MeHg), an environmental electrophilic pollutant, reportedly increases the risk of human cardiac events. We report that exposure to a low, non-neurotoxic dose of MeHg precipitated heart failure induced by pressure...

[BACKGROUND] Transcription factor Nrf2 (nuclear factor-erythroid 2-related factor 2) plays a key role in detoxification of electrophiles via formation of glutathione (GSH) adducts and subsequent excretion into extracellular spaces. We found that r...

The Journal of Toxicological Sciences   44(5) 327-333   Apr 2019   [Refereed]
<p>Metallothionein (MT) is a low-molecular-weight, cysteine-rich, and metal-binding protein that protects cells from the cytotoxic effects of heavy metals and reactive oxygen species. Previously, we found that transcriptional induction of endothel...

TOXICOLOGICAL SCIENCES   kfz091   2019   [Refereed]
Electrophiles can undergo covalent modification of cellular proteins associated with its dysfunction, thereby exerting toxicity. Small nucleophilic molecules such as glutathione protect cells from electrophilic insult by binding covalently to elec...
