“"Specific Aim 1 — characterize the cell-type-specific transcriptional response to chronic hypoxia in the developing mouse retina at single-cell resolution. We hypothesize that the rod photoreceptor lineage exhibits a distinct vulnerability profile relative to cone photoreceptors and Müller glia, and that this vulnerability is mediated by lineage-specific differences in the HIF-1-alpha-dependent unfolded protein response. To test this hypothesis we will perform single-cell RNA sequencing on retinal tissue from postnatal-day-twenty-one mice exposed to chronic hypoxia (twelve percent oxygen for fourteen days) versus normoxic littermate controls, with three biological replicates per condition. We will use Seurat-based clustering to identify cell-type populations, differential expression analysis with DESeq2 to identify hypoxia-responsive genes within each cell type, and gene-ontology enrichment to characterize the pathways differentially activated across cell types. Pre-existing pilot data (Figure 1) suggests that rod photoreceptors upregulate ATF4 and CHOP at substantially higher levels than other retinal cell types under matched hypoxic conditions, supporting the feasibility of the proposed approach. — Successful completion of this Aim will produce the first cell-type-resolved map of the hypoxic transcriptional response in the developing retina, and will identify the lineage-specific signaling axis hypothesized to drive selective rod vulnerability — a foundation for therapeutic interventions targeting retinopathy of prematurity."”
