Analysis of retinas subjected to hypoxia for 6 hours and subsequent reoxygenation for up to 16 hours. Hypoxic preconditioning protects photoreceptors from light damage in animal model. Results provide insight into the molecular basis of this protective effect.

(Submitter supplied) Neuroprotective therapies for retinal degeneration may be used to rescue retinal cells and preserve vision. Hypoxic preconditioning stabilizes the transcription factor HIF-1α in the retina and strongly protects photoreceptors in an animal model of light-induced retinal degeneration. Our data suggest that neuroprotection after hypoxic preconditioning of the retina is the result of the differential expression of a multitude of genes which may act in concert to protect visual cells against a toxic insult. more...

(Submitter supplied) Retinal ischemia is believed to initiate a series of events that leads to retinal neovascularization observed in several retinal diseases such as diabetetic retinopathy and retinal vein occlusion. Although some molecules such as VEGF and MCP-1 have been implicated in the process, its underlying mechanisms remain elusive. In order to identify genes associated with retinal ischemia, we performed gene expression analyses in retinas of mouse model of oxygen-induced retinopathy using DNA microarray technology.

(Submitter supplied) PURPOSE: Hyperoxia is toxic to photoreceptors, and this toxicity may be important in the progress of retinal dystrophies. This microarray study examines gene expression induced in the C57BL/6J mouse retina by hyperoxia over the 14-day period during which photoreceptors first resist, then succumb to, hyperoxia. METHODS: Young adult C57BL/6J mice were exposed to hyperoxia (75% oxygen) for up to 14 days. more...

(Submitter supplied) Purpose: Bulk RNA-Seq of wild-type mice retina after different hypoxic exposures, to evaluate the influence on retinal pathologies. Methods: Retinal mRNA profiles of C57BL/6J mice after 6 different hypoxic exposures were generated by deep sequencing (n=6) using paired-end high output sequencing (Illumina Novaseq 6000). Results: Longitudinal studies over 11 weeks in normobaric hypoxia revealed four classes of genes that adapted differentially to the long-term hypoxic condition. more...

(Submitter supplied) The goal of this study is to compare gene expression changes in retinal degenerate Royal College of Surgeons (RCS) rats following an injection of human neural progenitor cells (hNPCs) using RNA-seq, as compared to RCS rats receiving a sham surgery and wild-type Long Evans rats. These changes may lead to understanding of the therapeutic potential of hNPCs in inducing photoreceptor survival and visual function preservation.

(Submitter supplied) Retinal degeneration often affects the whole retina even though the disease-causing gene is specifically expressed in the light-sensitive photoreceptors. These retinal defects can potentially be determined by gene-expression profiling of the whole retina. In this study, we measured the gene-expression profile of retinas microdissected from a zebrafish pde6cw59 (pde6c) mutant. Its retinas display not only photoreceptor degeneration but also issues in other cell types starting from 4 days postfertilization (dpf). more...

(Submitter supplied) Aim: To identify the genes and non-coding RNAs (ncRNAs) involved in the neuroprotective actions of a dietary anti-oxidant (saffron) and of photobiomodulation. Methods: We used a previously published assay of photoreceptor damage, in which albino Sprague Dawley rats raised in dim cyclic illumination (12h 5 lux, 12h darkness) are challenged by 24h exposure to bright (1,000 lux) light. Experimental groups were protected against light damage by pretreatment with dietary saffron (1mg/kg/day for 21d) or photobiomodulation (10 J/cm2 at the eye, daily for 5d). more...
