Witryna1 kwi 2011 · X-linked juvenile retinoschisis (XLRS) is an orphan retinal disease in males caused by mutations in the RS1 gene. Previously we have characterized cone-rod homeobox (CRX)-responsive elements in the promoter region of RS1 driving selective gene expression in the retina. Here, we expanded our identification and functional … Witrynaa conditional Isl1 allele was generated and deleted speciﬁcally in the developing retina. Although RGCs formed in Isl1-deleted ret-inas, most underwent apoptosis, and few remained at later stages. By microarray analysis, we identiﬁed a distinct set of genes whose expression depended on Isl1. These genes are all downstream of
