Localization of TIMP-3 mRNA expression to the retinal pigment epithelium.

Abstract

Expression of TIMP-3 in the RPE is consistent with the recent demonstration of TIMP-3 mutations in patients with Sorsby's fundus dystrophy, a condition marked by the early onset of choroidal neovascularization in the macula. Unlike many of the recently described genes that cause human retinal disease, TIMP-3 is preferentially expressed in the RPE of the normal eye, as opposed to the photoreceptors.
