The role of the AU-rich elements of mRNAs in controlling translation.
Adenosine- and uridine-rich elements (AREs) located in 3'-untranslated regions are the best-known determinants of RNA instability. These elements have also been shown to control translation in certain mRNAs, including mRNAs for prominent pro-inflammatory and tumor growth-related proteins, and physiological anti-inflammatory processes that target ARE-controlled translation of mRNAs coding for pro-inflammatory proteins have been described. A major research effort is now being made to understand the mechanisms by which the translation of these mRNAs is controlled and the signalling pathways involved. This review focuses on the role of ARE-containing gene translation in inflammation, and the disease models that have improved our understanding of ARE-mediated translational control.
