FGF21 and the second coming of PPARγ

Cell. 2012 Feb 3;148(3):397-8. doi: 10.1016/j.cell.2012.01.020.


Peptide hormone fibroblast growth factor-21 (FGF21) has insulin-mimetic properties. Dutchak et al. now suggest that FGF21 also acts in an autocrine fashion in adipocytes and is required to mediate effects of the PPARγ agonist class of antidiabetic drugs. Does this new property improve FGF21's fledgling clinical prospects or endorse a clinical resuscitation of PPARγ agonists?
