Wakayama Symposium: Notch-FoxL2-α-SMA axis in eyelid levator muscle development and congenital blepharophimosis.
This review summarizes our recent findings regarding the Notch signaling pathway in regulating normal eyelid morphogenesis and its role in the pathogenesis of human congenital blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES). We used genetic and molecular biological approaches to investigate the mechanism by which Notch1 activation controls expression of FoxL2, which in turn activates smooth muscle actin gene expression in periocular mesenchyma to control eyelid levator smooth muscle formation.
