Abstract
The oncogenic Ets family of transcription factors is now recognized to play a key role in fibroblasts as it controls the expression of a variety of pro-fibrotic genes, including the induction of CCN2 by transforming growth factor β. A recent report (Baran et al., Am J Respir Cell Mol Biol. 2011 May 11) shows that mice containing a version of ets2 that is incapable of being phosphorylated are resistant to bleomycin-induced lung fibrosis. This latter paper is the subject of this commentary.
