Figure 3 Panel A: Zymography of paired serum samples from the 10 study participants with coronary artery disease shows digestion of gelatin at the 92 kDa band, indicative of the proenzyme form of MMP-9, during placebo (–) and hormone therapy (+) treatment periods of the study. Individual patients are identified by letters A through J and correspond with the identification letters in Figure 2. Panel B: Optical scanning of the zymograms from panel A, with values reported as densitometric units. Solid bars = placebo; open bars = estrogen. MMP = matrix metalloproteinase.
