Rapamycin Induced Autophagy and Suppression in Human Leukemia Cells Proliferation

Article Preview

Abstract:

To investigate the effect of autophagy induced by rapamycin (Rap) on proliferation of Human Leukemia Cells (HL60). HL60 cells are treated with rapamycin to induce autophagy. Then, Western blot is performed to examine the expression of Beclin1 and LC3. MTT assay is used to evaluate cell proliferation. The cell cycle is analyzed by flow cytometry (FCM). After treatment with rapamycin for 24 hours, LC3 is dramatically increased at protein level and autophagic activity is significantly increased. And MTT assay indicated that cell proliferation is inhibited by rapamycin. Compared with control group, more cells are arrested at G0/ G1 phases. We conclude that rapamycin can induce autophagy and suppress proliferation in HL60 cells.
