The activity of MMP-2. (a) The activity of MMP-2 was detected by zymography; MMP-2 will hydrolyze the gelatin at corresponding position and reveal transparent visible band under blue background; the brightness of band represents the activity of the enzyme. 62 KD brand is the active form of MMP-2; 72 KD brand is the form of pro-MMP-2. (b) The relative value of MMP-2 and pro-MMP-2 activity. Enzyme volume = strip area × (band gray − background gray). The results were standardized to MMP-2 enzyme volume and normalized to 1.0 in control group. Con: nondiabetic control group; DN: streptozotocin-induced diabetic group; HACE-L: low-dose-HACE-treated group; HACE-H: high-dose-HACE-treated group; Bena: benazepril. versus Con; versus DN.
