• treatment with tamoxifen at E0.5 or E12 prevents the progressive photoreceptor degeneration seen in heterozygous mice without cre expression
• treatment with tamoxifen at E0.5 also rescues the hyper-autofluorescence fundus phenotype
|
• following tamoxifen treatment at E12 or P1and P2, at 18 weeks of age hyper-autofluorescence spots of heterogeneous size and non-uniform distribution are seen on the fundus
• tamoxifen treatment at P1 fails to rescue the fundus hyper-autofluorescence phenotype
|
• tamoxifen treatment at E12 or P1 and P2 results in partial rescue of progressive arteriolar narrowing at 18 weeks of age
• tamoxifen treatment at E0.5 results in complete rescue of arteriolar narrowing at 18 weeks of age
• tamoxifen treatment at P1 fails to rescue arteriolar narrowing
|
• only treatment with tamoxifen at E0.5 resulted in photoreceptor numbers similar to controls after P18
• mice treated with tamoxifen at E12 or P1 have fewer photoreceptors by 18 weeks of age compared to controls
|
• cones show a distinct trailing edge/ring-shaped shape, reminiscent of a flame instead of the normal small, round, punctate shape at E12
|
• treatment with a single dose of tamoxifen at P1 fails to prevent progressive retinal photoreceptor degeneration
• treatment with 2 doses of tamoxifen at P1 and P2 partially rescues the progressive retinal photoreceptor degeneration
|
nervous system
• only treatment with tamoxifen at E0.5 resulted in photoreceptor numbers similar to controls after P18

|
cardiovascular system
• tamoxifen treatment at E12 or P1 and P2 results in partial rescue of progressive arteriolar narrowing at 18 weeks of age
• tamoxifen treatment at E0.5 results in complete rescue of arteriolar narrowing at 18 weeks of age
• tamoxifen treatment at P1 fails to rescue arteriolar narrowing
