Glutathione reductase plays a role in the metabolism of methylmercury degradation in Rhodotorula mucilaginosa [PDF]
Microbiology SpectrumMercury pollution is a kind of heavy metal pollution with great harm and strong toxicity which exists worldwide. Some microorganisms can convert highly toxic methylmercury into inorganic mercury compounds with significantly reduced toxicity.

Long-Term Environmental Methylmercury Exposure Is Associated with Peripheral Neuropathy and Cognitive Impairment among an Amazon Indigenous Population [PDF]
ToxicsWidespread contamination of the Amazon basin with mercury has been reported to occur since at least the mid-80s due to heavy gold mining activity. Although initial studies have indicated that this may lead to deleterious neurological consequences to the ...

Methylmercury demethylation and volatilization by animals expressing microbial enzymes [PDF]
Nature CommunicationsMercury is a highly toxic trace metal that readily biomagnifies in food webs where it is inaccessible to current bioremediation methods. Animals could potentially be engineered to detoxify mercury within their food webs to clean up impacted ecosystems ...

Methylmercury inhibits prolactin release in a cell line of pituitary origin [PDF]
Brazilian Journal of Medical and Biological Research, 2015 Heavy metals, such as methylmercury, are key environmental pollutants that easily reach human beings by bioaccumulation through the food chain. Several reports have demonstrated that endocrine organs, and especially the pituitary gland, are potential ...

Methylmercury toxic mechanism related to protein degradation and chemokine transcription
Environmental Health and Preventive Medicine, 2020 Methylmercury is an environmental pollutant that causes neurotoxicity. Recent studies have reported that the ubiquitin-proteasome system is involved in defense against methylmercury toxicity through the degradation of proteins synthesizing the pyruvate ...
