Figure 4.

MLC2 is highly phosphorylated in sudden cardiac deaths with mild coronary artery stenosis. In Case 1, the p-MLC2 was positively stained around LADA wall (A) with a focally magnified view in (B). Adjacent to the stenosed LADA segment, the interstitial small artery was also positively stained of p-MLC2 (C). In Case 2, the p-MLC2 was strong-positively stained around the LADA wall (D) with a focally magnified view in (E). Adjacent to the stenosed LADA segment, interstitial small artery was also positively stained p-MLC2 (F). In Case 3, the p-MLC2 was strong-positively stained around the LADA wall (G) with a focally magnified view in (H). Adjacent to the stenosed LADA segment, the interstitial small artery also had positively stained p-MLC2 (I). Magnification: 100× for upper images and 400× for bottom images. Red arrows indicate strongly positive staining.
