[Exploration of Mechanism for Meisoindigo-Inducing K562 Cell Apoptosis by Using Quantitative Proteomic Analysis].

Objective: To screen the differentially expressed proteins at the early stage of K562 cells treated with meisoindigo by using tandem mass tags (TMT)-based proteomics technology, and to explore the mechanism for meisoindigo-inducing apoptosis.

Methods: The half inhibitory concentration (IC) of mesoindigo on K562 cells was determined by CCK8. The flow cytometry was used to assay the apoptosis of K562 cells treated by meisoindigo or DMSO.
