Transcriptional and posttranscriptional regulation of IL-6 gene. The expression and degradation of IL-6 mRNA is regulated transcriptionally and posttranscriptionally by several proteins and microRNAs. Activation of these proteins and microRNAs determines the fate of IL-6 mRNA. NF-IL-6, nuclear factor of IL-6; Tax, transactivator protein; TAT, transactivator of the transcription; HBVX, hepatitis B virus X protein; Ahr, aryl hydrocarbon receptor; GR, glucocorticoid receptor; ER, estrogen receptor; Rb, retinoblastoma; PPARα, peroxisome proliferator–activated receptor α; miR, microRNA; IRAK1, IL-1 receptor–associated kinase 1; STAT3, signal transducer and activator of transcription 3; ORF, open reading frame; TTP, tristetraprolin; BRF1, butyrate response factor 1.
