glutathione plays an important role in reducing intestinal inflammation The of Protecting against the Severe Inflammatory Response Triggered by COVID-19 Frontiers | The emerging role

Typically, promoter hypermethylation silences gene expression, whereas hypomethylation upregulates gene expression, and overall promoter hypermethylation is negatively correlated with gene expression ( FIGURE 1 There are five members of the DNMT family, including three active enzymes, including DNMT1 which is responsible for maintaining the DNA methylation status during DNA replication, and DNMT3a and DNMT3b which mediate de novo methylation of CpG islands to generate new epigenetic marks ( Methyl-CpG-binding protein 2 (MeCP2) is a transcriptional repressor that specifically binds to methyl-CpGs and represses transcription from methylated gene promoters, or is a complex member of DNMT1 involved in DNA methylation maintenance ( in vitro and in vivo (Figure 1B)

Recent studies have confirmed that GPX4 activity is associated with chronic inflammation (86)
