Ontogeny of lens crystallins in marine cephalopods.

The Ontogeny and Specificity of Human Lens Proteins.

The ontogeny and specificity of human lens proteins were studied by immunologic and starch gel electrophoretic methods. Nine antigens were detected in noncataractous lenses by immunoelectrophoresis, while 16 components were formed on starch gel analysis. Of the different antigens, only one was specific for man and anthropoid apes. This antigen which reflected a high degree of species specificit...

Ontogeny and localization of the lens crystallins in Xenopus laevis lens regeneration.

The expression of αA- and βB1-crystallin during normal development and regeneration, and proteomic analysis for the regenerating lens in Xenopus laevis

PURPOSE To explore the expression of the lens crystallins (αA- and βB1-crystallin) in Xenopus laevis embryonic lens development and regeneration and to analyze the order of different crystallins generated in the regenerating lens. METHODS Real Time-PCR, Immunofluorescence, and 2D-PAGE were used to analyze the expressions of αA-crystallin and βB1-crystallin, and related factors during embryoni...

Gene sharing, lens crystallins and speculations on an eye/ear evolutionary relationship.

The crystallins comprise 80-90% of the water-soluble proteins of the transparent, cellular, refractive eye lens and are responsible for its optical properties. Comparative studies have established that the crystallins are surprisingly diverse and often differ among species in a taxon-specific fashion. In general, the crystallins are derived from or identical to metabolic enzymes or stress (smal...

Ontogeny of the eye of Caspian kutum (Rutilus frisii kutum) from prehatch to final larval stage

The present study examines the developmental stages of the eye retina in Caspian kutum during the pre-hatch stage to end of the larval stage. Fertilized eggs of Caspian kutum were obtained from Shahid Ansari Center for Reproduction of teleost fish (Guilan province, Iran). Sampling was done for one month until the larval stage completed and the yolk sac completely depleted. Samples were studied ...
