proenzyme

MAIN OUTCOME MEASURE: cellular mitochondrial function, cellular caspase 9 and caspase 3 activity, release of mitochondrial CytC and cleavage of caspase 3 proenzyme.

主要观察指标：细胞线粒体功能、细胞内caspase-9和caspase-3活性、线粒体细胞色素C的释放和caspase-3酶原的降解。

Of the system, P0 is one of the important components; it has two activities, MPO and DPO, and exists as proenzyme PPO in the insect.

其中，PO是PPO系统的关键成分之一，它是以酶原形式PPO存在于昆虫体内，具有MPO和DPO两种酶活性。

The carbon tetrachloride-induced hepatic fibrosis rat models were used. MMP-3 proenzyme protein expression in the different stages of liver fibrosis was measured by half quantitative analysis of Western blot.

建立四氯化碳中毒性大鼠肝纤维化模型，采用半定量Western免疫印迹方法，对肝纤维化不同阶段肝内MMP-3的酶原蛋白的表达水平进行了检测。
