Differential gene expression in mouse retina related to regional differences in vulnerability to hyperoxia

ABSTRACT: 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. Methods: Young adult C57BL/6J mice raised in dim cyclic illumination (12h 5lux, 12h darkness) were exposed to hyperoxia (75% oxygen for 2w). Retinas were collected from hyperoxia-exposed and control animals without fixation, and divided into superior and inferior halves. RNA was extracted from each sample, purified and hybridised to mouse 1.0 ST arrays (Affymetrix). The consistency of the microarray results was assessed with quantitative PCR for selected genes. Expression data were analysed to identify genes and ncRNAs whose differential expression between superior and inferior retina could be associated with relative vulnerability to hyperoxia.

Project description:Proper spatial differentiation of retinal cell types is necessary for normal human vision. Many retinal diseases, such as Best disease and male germ cell associated kinase (MAK)-associated retinitis pigmentosa, preferentially affect distinct topographic regions of the retina. While much is known about the distribution of cell types in the retina, the distribution of molecular components across the posterior pole of the eye has not been well-studied. To investigate regional difference in molecular composition of ocular tissues, we assessed differential gene expression across the temporal, macular, and nasal retina and retinal pigment epithelium (RPE)/choroid of human eyes using RNA-Seq. RNA from temporal, macular, and nasal retina and RPE/choroid from four human donor eyes was extracted, poly-A selected, fragmented, and sequenced as 100 bp read pairs. Digital read files were mapped to the human genome and analyzed for differential expression using the Tuxedo software suite. Retina and RPE/choroid samples were clearly distinguishable at the transcriptome level. Numerous transcription factors were differentially expressed between regions of the retina and RPE/choroid. Photoreceptor-specific genes were enriched in the peripheral samples, while ganglion cell and amacrine cell genes were enriched in the macula. Within the RPE/choroid, RPE-specific genes were upregulated at the periphery while endothelium associated genes were upregulated in the macula. Consistent with previous studies, BEST1 expression was lower in macular than extramacular regions. The MAK gene was expressed at lower levels in macula than in extramacular regions, but did not exhibit a significant difference between nasal and temporal retina. The regional molecular distinction is greatest between macula and periphery and decreases between different peripheral regions within a tissue. Datasets such as these can be used to prioritize candidate genes for possible involvement in retinal diseases with regional phenotypes.

Project description:Background: Nrf2 is an essential cytoprotective transcription factor. However, association of Nrf2 in organ development and neonatal disease is rarely examined. Hyperoxia exposure to newborn rodents generates pulmonary phenotypes which resemble bronchopulmonary dysplasia (BPD) of prematurity. Methods: To investigate the role of Nrf2 in lung maturation and BPD pathogenesis, Nrf2-deficient (Nrf2-/-) and wild-type (Nrf2+/+) neonates were exposed to air or hyperoxia (O2). Transcriptome analysis determined Nrf2-directed mechanisms in premature lung. Lung injury was assessed by bronchoalveolar lavage analysis and histopathology. Results: In Nrf2-/- neonates, basal expression of cell cycle machinery, redox balance, and lipid/carbohydrate metabolism genes were suppressed while immunity genes were overexpressed compared to Nrf2+/+ pups. O2-induced mortality and pulmonary inflammation/injury were significantly higher in Nrf2-/- than in Nrf2+/+. Lung DNA lesion and oxidation were greater in Nrf2-/- than in Nrf2+/+, constitutively and after O2. Nrf2-dependent genes modulated cellular growth/proliferation, defense, immunity, and lipid metabolism against hyperoxia. Bioinformatic elucidation of Nrf2 binding motifs and augmented O2-induced inflammation in genetically deficient neonates validated Gpx2 and Marco as Nrf2 effectors. Conclusion: Overall, Nrf2 in underdeveloped lungs orchestrated cell cycle, morphogenesis, and immunity as well as cellular defense constitutively and under oxidant stress. Results provide putative molecular mechanisms of Nrf2-directed lung alveolarization and BPD of prematurity. PARALLEL study design with 42 samples comparing 14 groups of age (P1 to P4 corresponding to day 0 to day 3 animals), gene, and exposure: (4 groups Nrf+/+ wild type P1-P4 air exposure) (4 groups Nrf -/- knockout P1-P4 air exposure), (3 groups Nrf+/+ wild type P2-P4 with 100 percent O2 (hyperoxia exposure) and 3 groupsNrf -/- knockout P2-P4 with 100 percent O2 (hyperoxia exposure)) Biological replicates: 3 per group
