WebAug 1, 2024 · To determine the overall toxicity of MeHg in tissues, studies should evaluate low concentrations of Hg2+. Although demethylation is involved, the participating enzymes or underlying mechanisms are unknown; in addition, the low cell membrane permeability of Hg2+ makes these analyses challenging. WebAlone, it is unable to demethylate H3 'Lys-4' on nucleosomes and requires the presence of RCOR1/CoREST to achieve such activity. It may also demethylate 'Lys-9' of histone H3, a specific tag for epigenetic transcriptional repression, thereby leading to derepression of androgen receptor target genes. Mutations affecting this gene can result in ...
Demethylating agents are chemical substances that can inhibit methylation, resulting in the expression of the previously hypermethylated silenced genes (see Methylation#Cancer for more detail). Cytidine analogs such as 5-azacytidine (azacitidine) and 5-azadeoxycytidine (decitabine) are the most commonly used demethylating agents. They work by inhibiting DNA methyltransferases. Both compounds have been approved in the treatment of myelodysplastic syndrome (MDS) by F…
