Activation of ErbB and WNT signaling pathways in kidneys from Cdh16Cre::Tfebfs mice.Transcriptional and biochemical analyses were performed on Cdh16Cre and Cdh16Cre::Tfebfs mice. (A,B) Tables show the relative increase of genes related to the ErbB (A) and WNT (B) pathways in the microarray analyses performed on kidneys from P0 Cdh16Cre::Tfebfs mice. Graphs show real-time PCR validations performed on kidneys from Cdh16Cre::Tfebfs mice at different stages (P0, P12, P30). Data are shown as the average (± SEM) of at least three Cdh16Cre::Tfebfs mice normalized versus wild-type mice.
