OBJECTIVE To determine the relationship between retinal alpha A-crystallins and the development of retinal degeneration in rd, rds and C3H mice. METHODS Total retinal mRNA was prepared from the retina of (rd) retinal degeneration, (rds) retinal degeneration slow, C3H and control C3B mice during the progress of retinal degeneration (Post-natal 3, 4, 5, 6, 8 weeks). The retinal expression of alpha A-crystallins was determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis. RESULTS Expression of retinal alpha A-crystallins is rather stable in rd, rds and C3H mice during the progress of their retinal degeneration. The expression is also similar to that in normal C3B mice but different to that in Royal college of surgeons(RCS) rats. CONCLUSIONS Retinal alpha A-crystallins may not involve in the course of RP in rd, rds and C3H mice. The molecular mechanism of RP in rd, rds and C3H may be different to that in RCS rat.

D008809	Mice, Inbred C3H	An inbred strain of mouse that is used as a general purpose strain in a wide variety of RESEARCH areas including CANCER; INFECTIOUS DISEASES; sensorineural, and cardiovascular biology research.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D012162	Retinal Degeneration	A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D012333	RNA, Messenger	RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
