Chaperone-mediated autophagy in health and disease.

abstract：:Purified plasma membrane vesicles isolated from multidrug-resistant human KB-V1 cells accumulate [3H]vinblastine in an energy-dependent manner. The accumulation of [3H]vinblastine in the presence of ATP is a saturable process. ATP can be replaced by other purine nucleotide triphosphates, of which GTP is the most effic...
