给饥饿的大鼠或小鼠服用溶酶体半胱氨酸蛋白酶的特异性抑制剂胰肽,可抑制自溶酶体蛋白的降解,并导致其肝脏中自溶酶体的积累。免疫印迹法检测肝脏匀浆在体内的自噬通量显示,在白细胞介素处理的动物肝脏中,选择性自噬底物p62和自噬体膜蛋白LC3-II水平升高。Percoll密度梯度离心可用于从未处理和白细胞蛋白酶处理的动物肝脏中分离自溶酶体。此外,可以检查自溶酶体是否存在隔离的细胞质蛋白以及降解中间体。
Administration of leupeptin, a specific inhibitor of lysosomal cysteine proteinases, to starved rats or mice inhibits autolysosomal protein degradation and results in accumulation of autolysosomes in their livers. Immunoblotting of liver homogenates to examine autophagic flux in vivo reveals elevated levels of the selective autophagy substrate p62 and the autophagosomal membrane protein LC3-II in the livers of leupeptin-treated animals. Percoll density gradient centrifugation can be used to isolate autolysosomes from the livers of untreated and leupeptin-treated animals. Moreover, autolysosomes can be examined for the presence of sequestered cytoplasmic proteins as well as degradation intermediates.
