Article Title: Rexinoid NEt-3IB Promotes Resident Macrophage Gene Expression and Mitigates Desiccation-Induced Ocular Surface Disease

doi: 10.1167/iovs.67.4.31

Figure Lengend Snippet: Effects of rexinoid treatment on macrophage gene and protein expression in the desiccation stress dry eye model and potential macrophage-derived IGF-1/IGF-1R signaling axis. ( A ) Heatmaps showing z -score–scaled expression of selected latent-time–associated genes in four treatment groups (NS, None [untreated], Veh, and NEt-3IB) in conjunctival monocyte/macrophage lineage cells sorted from CD45⁺ cells after 5 days of desiccating stress (DS5) ( P adj < 0.001). Genes are organized into five functional categories. The color scale represents z -scores of normalized expression ( blue , low; red , high). These data show desiccating stress–associated shifts in macrophage gene programs and their modulation by NEt-3IB, including enrichment of reparative and growth factor–related genes such as Igf1 . Full gene names for the abbreviations are provided in . ( B ) Representative flow cytometry histograms and quantification validating selected macrophage-associated markers in conjunctival immune cells. ( Left ) Representative histograms of CX3CR1 staining with fluorescence-minus-one (FMO) control, with corresponding quantification of the percentage of CD45⁺CD11b⁺CX3CR1⁺ cells. ( Right ) Representative histograms of IGF-1 staining with FMO control, with corresponding quantification of the percentage of CD45⁺CD11b⁺Mrc1⁺IGF-1⁺ cells. Compared with DS5 no treatment and DS5+vehicle controls, DS5+NEt-3IB increased the proportion ofx CX3CR1⁺ and Mrc1⁺IGF-1⁺ myeloid cells. Each dot represents one biological replicate; bars show mean ± SEM. Statistical significance is indicated as shown: ** P < 0.01; **** P < 0.001; **** P < 0.0001; ns, not significant. ( C ) Representative immunofluorescence images showing IGF-1R/WGA/DAPI staining of wholemount conjunctiva showing surface view ( top ) and βIII-tubulin/IGF-1R/DAPI staining in the cornea ( bottom ). IGF-1R localization is shown because IGF-1 is produced by ocular surface resident macrophages, suggesting a potential macrophage-derived IGF-1/IGF-1R signaling axis acting on ocular surface epithelial and neural compartments during DS. Scale bar : 100 µm.

Figure Lengend Snippet: Overall survival for women with breast cancer based on IR and IGF-1R protein expression in KMPlot.com . KMPlot.com was used to generate overall survival Kaplan-Meier plots. The dataset used was not from our cohort but from Tang and colleagues ; n = 65 patients had IR (A) and IGF1R (B) protein expression available. The patients were split using the “auto select best cutoff” percentile option in KMPlot. No other restrictions were added to the analysis. The plots show hazard ratios with 95% confidence intervals in parentheses . Abbreviations: IGF-1R, IGR-1 receptor; IR, insulin receptor.
