(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) 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...

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) Cone photoreceptors are the primary initiator of visual transduction in the human retina. Dysfunction or death of rod photoreceptors precedes cone loss in many retinal and macular degenerative diseases, suggesting a rod-dependent trophic support for cone survival. Rod differentiation and homeostasis are dependent on the basic motif leucine zipper transcription factor NRL. The loss of Nrl in mice (Nrl-/-) results in a retina with predominantly S-opsin containing cones that exhibit molecular and functional characteristics of WT cones. more...

(Submitter supplied) The mammalian central nervous system (CNS) is capable of tolerating chronic hypoxia, but cell type-specific responses to this stress have not been systematically characterized. In the Norrin-knockout (NdpKO) mouse, a model of familial exudative vitreoretinopathy (FEVR), developmental hypovascularization of the retina produces chronic hypoxia of inner nuclear layer (INL) neurons and Muller glia. We have used single-cell RNA sequencing, untargeted metabolomics, and metabolite labeling from 13C-glucose to compare wild type and NdpKO retinas. more...

(Submitter supplied) Background: Hypoxia can affect aerobic organisms profoundly. Biological responses to extreme hypoxia have been well studied. However, it is not well characterized how living organisms respond to mild hypoxia, and how they distinguish different levels of hypoxia. Results: We examined the transcriptional responses of locusts using microarrays to reveal their strategies to cope with mild hypoxia. Mitochondrial activities were systemically suppressed, mainly involving energy production and mitochondrial biogenesis. more...

(Submitter supplied) Skeletal muscle is the largest tissue in the body and mainly relies on mitochondrial oxidative metabolism for sustainable ATP production. Reduced oxygen availability, also known as hypoxia, can be caused by high altitude or pathology and impacts mitochondria. Whereas long-term hypoxia results in increased reliance on glycolysis, reduced fatty acid oxidation and a decreased skeletal muscle mass, the in vivo mechanisms of adaptation of skeletal muscle to acute hypoxia remain elusive. more...
