Tcf4 CTG Repeat Expansion Induces RNA Toxicity and MBNL-Associated Splicing Dysregulation in a Mouse Model of Fuchs Endothelial Corneal Dystrophy
Purpose To determine whether a Tcf4 CTG repeat knock-in mouse model of Fuchs endothelial corneal dystrophy (FECD) recapitulates molecular features of repeat RNA toxicity and MBNL-associated splicing dysregulation in corneal endothelial cells in vivo. Methods Corneal endothelial tissues from 20-, 40-, and 60-week-old wi...
