Loss of α3/α4(IV) Collagen from the Glomerular Basement Membrane Induces a Strain-Dependent Isoform Switch to α5α6(IV) Collagen Associated with Longer Renal Survival in Col4a3 −/− Alport Mice

Abstract excerpt

Mutations in COL4A3/4/5 genes that affect the normal assembly of the alpha3/4/5(IV) collagen network in the glomerular basement membrane (GBM) cause Alport syndrome. Patients progress to renal failure at variable rates that are determined by the underlying mutation and putative modifier genes. Col4a3(-/-) mice, a model for autosomal recessive Alport syndrome, progress to renal failure significantly slower on the...
