GM dysbiosis and inflammation also induce epigenetic alterations in cytokine genes, such as IL-1β, IL-6, TNF-α, NF-kB, BTLA, IL-18R1, TGF-β, P13k/Akt1, Ctnnb1, and Hsp90aa1, as well as DNMTs, HDACs, and DAT1 associated with the development and progression of metabolic disorders and/or NPDs. This evidence concerns the gene TNF and metabolic disease.
