title: [Influence of mutant genes on crystallin synthesis in the forming mouse lens. II. Fidget and ocular retardation genes].
abstract: The beginning of synthesis and the localization of alpha- and gamma-crystallins in the developing lenses of the 10-13 and 15 days old mouse embryos of the genotypes fi/fi +/+, +/+ or/or, fi/fi or/or and +/+ +/+ were studied by means of indirect immunofluorescence. The synthesis of crystallins in the mutant embryos with the exception of the embryo +/+ or/or was shown to begin somewhat later than in the normal ones but to proceed in all defective lenses, irrespective of the degree of defect. Hence, the activation of the genes controlling the synthesis of alpha-crystallins begins at the early stages of lens development and the synthesis of these proteins proceeds even during the abnormal with the slowing down of the formation of primary lens fibers. In the cases of strong defects of morphogenesis in the fi/fi +/+ and, especially, fi/fi or/or, embryos gamma-crystallins were not detected. The synthesis of gamma-crystallins appears to begin at the final stages of lens fiber differentiation.
