Figure 4From: BRG1 overexpression in smooth muscle cells promotes the development of thoracic aortic dissection BRG1 expression is negatively correlated to the rate of contractile SMCs in TAD specimens. (A) Representative images of immunohistochemical staining for α-SMA in aortic media of TAD and normal tissues. The percentage of α-SMA positive cells in TAD tissues were significantly lower than that in the normal tissues. Bars =50 μm. (B) Dot plots represent log10percentage of α-SMAhigh cells against log10BRG1 protein expression level. The lines represent approximated curves. The correlation coefficient (r) and the P value indicate the statistical significance of the negative correlation between the x and y variables.Back to article page
