Abstract:
:The Crk and CrkL adaptor proteins have SH2 and SH3 domains and play essential overlapping, as well as distinct, roles in many biological processes, ranging from cell structure and motility to proliferation. Conditional ablation of both Crk and CrkL in neuronal progenitor cells, using a Nestin-Cre transgene, resulted in severe defects in postnatal eye development, including progressive eye closure, lens rupture, and retinal malformation. These phenotypes were not observed in the presence of a single wild-type allele of either Crk or CrkL. We found that the lens in knockout mice started to rupture and disintegrate between postnatal days 7 and 12, although the structure of the retina was relatively well maintained. As the lens deteriorated further, the outer nuclear layer in the posterior of the retina enlarged and developed ruffles. Cre recombination occurred in the lens and retina of the knockout mice. Furthermore, the posterior lens capsule of the knockout mouse was thinner at postnatal days 0.5 and 3, suggesting that the defective lens capsule caused rupturing of the lens near the posterior pole. These results indicate that Crk and CrkL play essential overlapping roles in postnatal lens development.
