Abstract
|
|
|
|
It is generally known that mutations in any of several genes encoding photoreceptor-specific proteins have resulted in retinitis pigmentosa (RP), a disease characterized by losing photoreceptor function with progressive degeneration of photoreceptor cells and eventually leading to blindness. To study the procure and cure of photoreceptor degeneration, we produced transgenic mice. Transgene consisted of a 12.5kb genomic DNA fragment that contains mutated pig rhodopsin gene (Pro-347-Ser) including both the 5’-franking (4.0 kb) and the 3’-franking (2.9 kb) sequences. This gene was used for the production of transgenic mouse. The mutated rhodopsin DNA was microinjected into male pronuclei of fertilized mouse (C57BL /6]) embryos. We detected transgenic animals harboring mutated rhodopsin gene by PCR and Southern blot analysis. These transgenic mice showed stable transmission of microinjected rhodopsin gene into their offspring. Therefore these animals will provide a novel approach to study the mechanism of the photoreceptor degeneration and be provided as a disease model for the treatment of the blind in human.
