Regulation of BET protein expression and functions in diseases. Expression and activity of BET proteins are regulated at different levels, including (A) transcription by 5-hydroxymethylcytosine (5-hmC) at the BRD4 promoter, (B) messenger RNA (mRNA) stability by binding of microRNA (miRNA) to the 3′ untranslated region (UTR) of BRD4 mRNA transcripts, and (C) translation by N 6-methyladenosine (m6A) modification of mRNA (Rahman et al., 2011).
