β-Catenin and Smad3 regulate the activity and stability of myocardin-related transcription factor during epithelial–myofibroblast transition

Two novel mechanisms are shown by which injury of intercellular junctions via β-catenin promotes epithelial–myofibroblast transition. β-Catenin interacts with Smad3, thereby preventing the inhibitory effect of the latter on myocardin-related transcription factor (MRTF), and maintains MRTF stability...

Description
Summary:Two novel mechanisms are shown by which injury of intercellular junctions via β-catenin promotes epithelial–myofibroblast transition. β-Catenin interacts with Smad3, thereby preventing the inhibitory effect of the latter on myocardin-related transcription factor (MRTF), and maintains MRTF stability by inhibiting Smad3-mediated, GSK-3β–dependent degradation of MRTF.
