Pairwise comparison of differentially expressed genes between Caveolin-1 knockout (Cav1-KO) and wildtype control (Control) mouse lungs in normoxic conditions. Male (control n=3, Cav1-KO n=3) and female (control n=3, Cav1-KO n=2) comparisons were performed separately. The top 50 differentially expressed genes (DEG) upregulated and downregulated are shown in descending order of significance based on adjusted P-value (P adj ) for (A) female and (B) male lungs. DEG thresholds were set at Log2Foldchange > 1, P adj <0.05. Z-score coloring represents relative gene expression across all groups. Samples are sorted by complete hierarchical clustering. Gene Ontology (GO) analysis for (C) Female and (D) Male samples are shown as the top 20 gene ontologies in descending order of P adj . The X-axis represents the number of DEGs in this comparison that underlies the significant GO.

Summary of the effect of Caveolin-1 (Cav1) genetic status, hypoxia, and sex on the expression of known pulmonary arterial hypertension (PAH) risk factors and summary figure of transcriptional changes found in Cav1 genetic modulation. (A) A heatmap of genes associated with heritable PAH risk. Each group represents the average expression of these genes across all samples in the group. Genes are organized by hierarchical clustering to demonstrate similar patterns of expression across the groups. (n = 2 – 3) (B) Summary figure showing which transcriptional pathways are modulated during global Cav1 knockout or endothelial Cav1 reconstitution. Gene ontologies are distinguished by which sex, or both, they show significant change.

Article Title: Transcriptomic profiling of the sex-linked biological pathways of severe pulmonary arterial hypertension associated with endothelial cell caveolin-1 depletion and chronic hypoxia

doi: 10.3389/fphys.2026.1794886

Figure Lengend Snippet: Summary of the effect of Caveolin-1 (Cav1) genetic status, hypoxia, and sex on the expression of known pulmonary arterial hypertension (PAH) risk factors and summary figure of transcriptional changes found in Cav1 genetic modulation. (A) A heatmap of genes associated with heritable PAH risk. Each group represents the average expression of these genes across all samples in the group. Genes are organized by hierarchical clustering to demonstrate similar patterns of expression across the groups. (n = 2 – 3) (B) Summary figure showing which transcriptional pathways are modulated during global Cav1 knockout or endothelial Cav1 reconstitution. Gene ontologies are distinguished by which sex, or both, they show significant change.
