Sections of LV tissue are stained with collagen I and III, CcOX4, and integrin α5 (Intg α5) antibodies using fluorescent microscopy. There is loss of collagen I and III, CcOX4, and Intg α5 that is restored by PD 166793 and infliximab (Panel A). In Panel B, overlay of collagen I and III and Intg α5 with CcOX4 and DAPI at higher power demonstrates a prominent loss of CcOX4 and Intg α5 in the subsarcolemmal area of cardiomyocytes in the ACF LV, which is restored by PD 166793.
