Abstract

Crim1 is a transmembrane protein that regulates the bioavailability of growth factors such as VEGFA. Crim1KST264/ KST264 hypomorphic mice develop renal disease characterized by glomerular cysts and loss of endothelial integrity, progressing to peritubular and pericystic fibrosis. Peritubular capillary endothelial cells display morphological changes as well as detachment from the basement membrane. In this study, gene expression profiling of CD31+ endothelial cells isolated from Crim1KST264/KST264 kidneys showed up-regulation of transcripts associated with fibrosis (Col3a1, Loxl1), endothelial dysfunction (Abp1, Dcn, Lcn2), biomarkers of renal damage (Lcn2, Havcr1/Kim1) as well as evidence fo..
