Figure 2. Doxycycline and aortic valve MMP activation in CAVD.

Figure 2

(A) Examples of in vivo CT angiography, RP805 (MMP-targeted) microSPECT, and fused microSPECT and CT transverse images of control (top row) and doxycycline-treated (for 3 months) apoE−/− mice (bottom row) after 6 months of high fat diet. Arrows point to aortic valve area. cpv: counts per voxel. (B) Quantification of RP805 uptake in CAVD on in vivo SPECT images. n = 8 in each group. (C) Examples of ex vivo RP805 planar images of the heart and aorta in control (left) and doxycycline-treated apoE−/− mice on high fat diet (right). Arrows point to aortic valve area. cpp: counts per pixel. Three point sources are seen in the field of view. (D) Quantification of RP805 uptake in aortic valve area on ex vivo planar images. n = 8 in each group.
