(Submitter supplied) We used microarray gene profiling to study the transcriptome of retinas lacking CRB2 during late retinal development. Unexpectedly, the retinas of newborn mice lacking CRB2 showed no changes in the transcriptome during retinal development.

(Submitter supplied) mRNA transcript levels in embryonic day 15.5 (E15.5), E17.5 and postnatal day 1 (P1) mouse Crb1KOCrb2ΔRPC against mouse Crb1KO neuroretina (Run1), and in E15.5 mouse Crb1KOCrb2ΔRPC against wild type neuroretina (Run2) were analyzed. A comparison between Crb1KOCrb2ΔRPC and Crb1KO retina, at E15.5, or E17.5, or P1 on 100% C57BL/6JOlaHsd, yielded only subtle persistent changes at the transcriptional level over time (Figure 1 G-I, respectively), despite significant differences in morphology. more...

(Submitter supplied) The crumbs cell polarity complex plays a crucial role in apical-basal epithelial polarity. When human CRB1 is mutated, it results in autosomal recessive Leber congenital amaurosis and retinitis pigmentosa, with no established genotype-phenotype correlation. Using the oko meduzym289/m289 (crb2a-/-) zebrafish model, we performed integrative transcriptomic and methylomic analysis to identify dysregulated genes and pathways. more...

(Submitter supplied) The rd1 mouse retina is a well-studied model of retinal degeneration where rod photoreceptors undergo cell death beginning at postnatal day P10 until P21. This period coincides with photoreceptor terminal differentiation in a normal retina. We have used the rd1 retina as a model to investigate early molecular defects in developing rod photoreceptors prior to the onset of degeneration. Using a microarray approach, we performed gene profiling comparing rd1 and wild type retinas at four time points starting at P2, prior to any obvious biochemical or morphological differences, and concluding at P8, prior to the initiation of cell death. more...

Analysis of rd1 retinas starting at P2 (prior to obvious biochemical/morphological differences) and ending at P8 (early degenerative changes present, but prior to onset of rod photoreceptor cell death). Results provide insight into molecular mechanisms underlying photoreceptor development.

(Submitter supplied) Purpose: The goal of the present study is to provide an independent assessment of the retinal transcriptome signatures of the C57BL/6J (B6) and DBA/2J (D2) mice and to enhance existing microarray datasets for accurately defining the allelic differences in the BXD recombinant inbred strains. Methods: Retinas from both B6 and D2 mice (3 of each) were used for the RNA-seq analysis. Transcriptome features were examined for both strains. more...

(Submitter supplied) Mutations in the membrane frizzled-related gene (Mfrp) are linked to posterior microphthalmia, retinitis pigmentosa and nanophthalmia in humans. In homozygous Mfrprd6 mice, a splice site mutation causes a slow photoreceptor degeneration characterized by shortening and disorganization of outer segments with eventual photoreceptor loss. To better understand the function of MFRP in the retina, microarray analysis was carried out in mutant and control mice at postnatal day14 (P14), prior to the loss of photoreceptors. more...

(Submitter supplied) Purpose: In the C57BL/6J mouse retina, hyperoxia-induced degeneration of photoreceptors shows strong regional variation, beginning at a locus ~0.5mm inferior to the optic disc. To identify gene expression differences that might underlie this variability in vulnerability, we have used microarray techniques to describe regional (superior-inferior) variations in gene expression in the retina.

(Submitter supplied) Transcription profiling by array of mouse male retinas to investigate IGF-I-induced chronic gliosis and retinal stress IGF-I exert multiple effects in different retinal cell populations in both physiological and pathological conditions. Transgenic mice overexpressing IGF-I in the retina showed impaired electroretinographic responses at 6-7 months of age that worsen with age. This retinal neuronal dysfunction was correlated with the loss of rod photoreceptors, bipolar, ganglion and amacrines cells. more...

(Submitter supplied) Microglia have important remodeling functions in development and disease. There is evidence for molecular diversity of microglia suggesting they may exist in distinct functional states to differentially impact CNS health and function. To better understand this in development, we profiled microglia of a discrete developing CNS region, the murine retina. We find that retinal microglia transition through unique transcriptional states and identify a population with peak density postnatally that resemble adult disease-associated microglia (DAM) and CD11c+ microglia of developing white matter, we term DAM-like. more...
