Figure Lengend Snippet: Figure 7 Inhibition of HIF-1a by PX-478 improves atherosclerosis through the SMPD3eceramide axis. Eight-week-old ApoEe/e mice were administered with PX-478 (5 mg/kg) or vehicle every other day and fed a WD for 8 weeks. (A) Schematic diagram of the mouse model illustrating the concept of mouse injection with PX-478. (B) Left, representative oil red O staining of cross-sections of aortic roots. Scale bar, 500 mm. Right, quantification of aortic root lesion areas. n Z 7 per group. (C, D) Quantitation of ceramide concentrations in plasma (C) and eWAT (D), n Z 6 per group. (E, F) The levels of plasma total cholesterol (E) and triglyceride (F), n Z 7 per group. (G) FPLC analysis of plasma cholesterol levels in mice. (H) Immunofluorescence staining of atherosclerotic lesions with MAC-2 antibody and calculated MAC-2 positive areas in the plaques (n Z 3 per group). Scale bar, 500 mm. All data are presented as the mean SEM. ManneWhitney U test (B, D), Two-tailed Student’s t-test (C, E, F, H): *P < 0.05, **P < 0.01 compared to the vehicle group. See also Fig. S5.
