Figure Lengend Snippet: a Real-time polymerase chain reaction (RT-PCR) was used to measure mRNA expression of PDE4A, PDE4B, PDE4C, and PDE4D in the aorta tissues of control mice and hypertensive mice (fold change vs. one of controls). b Representative western blot showing PDE4D expression in aorta tissues. c Quantification of PDE4D expression normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) protein. d Representative immunohistochemical staining of PDE4D. Arrows indicate positive areas. e Quantification of the percentage of PDE4D-positive area. n = 4 in control group, n = 8 in hypertensive group. Data are expressed as mean ± standard error of mean (SEM). Two-tailed Student’s t test was performed to compare differences between two groups. * p < 0.05, *** p < 0.001. L lumen.
