Article Title: Early apelin receptor activation attenuates elastase-induced emphysema and preserves endothelial apelin receptor signaling in mice

Figure Lengend Snippet: (A) Experimental design for elastase administration and lung RNA sequencing. Eleven-week-old male C57BL/6J mice received intratracheal elastase at 2 mg/kg, and lungs were collected at day 1, week 1, and week 2. (B) Principal component analysis of lung bulk RNA-sequencing data from control and elastase-treated mice. (C) Overview of the CIBERSORTx workflow. A signature matrix generated from mouse lung single-cell RNA-sequencing data (GSE168299) was applied to bulk lung RNA-sequencing profiles from control and elastase-treated mice. (D) Estimated proportions of lung cell-type-associated signatures inferred by CIBERSORTx. (E) Inferred aerocyte capillary endothelial (aCap) and general capillary endothelial (gCap) fractions. (F) Lung expression of Apln and apelin receptor/APJ-associated transcript in bulk RNA-sequencing data. (G) Lung apelin protein levels measured by enzyme-linked immunosorbent assay. Data are means ± SEM; n = 3–6 mice per group. P values were determined by one-way ANOVA with Dunnett’s multiple-comparisons test. * P < 0.05, ** P < 0.01, *** P < 0.001.
