Elevating beta-catenin signaling converts endothelial cells in typically fenestrated central nervous system vasculature to a blood-brain barrier (BBB) phenotype and promotes a BBB gene expression program and chromatin landscape.
Discs large homologue 1 (Dlg1) activates beta-catenin (i.e., canonical Wnt) signaling in CNS endothelial cells to regulate retinal angiogenesis and the development and maintenance of the blood-brain and blood-retina barriers.
In vitro culture of brain endothelial cells leads to a rapid loss of the blood-brain barrier transcriptional and accessible chromatin landscapes that is resistant to the effects of beta-catenin stabilization.
A novel ALS-associated variant in UBQLN4 impairs proteasome function and beta-catenin degradation to drive aberrant axon morphogenesis in motor neurons.
The primary molecular mechanosensor involved in a physiological process of mechanically induced cell fate differentiation is revealed here for the first time in vivo, highly sensitive and potentially shared by all metazoan epithelia.
