Reducing TRPC1 Expression through Liposome-Mediated siRNA Delivery Markedly Attenuates Hypoxia-Induced Pulmonary Arterial Hypertension in a Murine Model

Figure 5

Immunofluorescent (IF) staining for HIF-1α+ cells and Ku-70+ cells in medial layer of large pulmonary arterioles (PA) by day 28 after pulmonary arterial hypertension (PAH) (). ((a) to (c)) Cellular expression of hypoxia-inducible factor- (HIF-) 1α in PA (white arrow) after double staining (i.e., α-SMA-HIF-1α) in the three groups of animals (400x). (d) versus other groups with different symbols (, †, ‡), . ((e) to (g)) Identification of Ku-70+ cells in PA (white arrow) using double staining (i.e., α-SMA-Ku-70) in the three groups (400x). (h) versus other groups with different symbols (, †, ‡), . The scale bars in right lower corners represent 20 μm. Blue fluorescence represents DAPI-stained nuclei. Statistical analysis in (d) and (h) using one-way ANOVA, followed by Bonferroni multiple comparison post hoc test. Symbols (, †, ‡) indicate significance (at 0.05 level).
