title: Turning it up a Notch: cross-talk between TGF beta and Notch signaling.
abstract: Signaling through both the transforming growth factor beta (TGF beta) superfamily of growth factors and Notch play crucial roles during embryonic pattern formation and cell fate determination. Although both pathways are able to exert similar biological responses in certain cell types, a functional interaction between these two signaling pathways has not been described. Now, three papers provide evidence of both synergy and antagonism between TGF beta and Notch signaling. These reports describe a requirement for Notch signal transducers in TGF beta- and BMP-induced expression of Notch target genes, as well as in BMP-controlled cell differentiation and migration. These papers uncover a direct link between the Notch and TGF beta pathways and suggest a critical role for Notch in some of the biological responses to TGF beta family signaling.
