A preliminary study on the econazole induced endoplasmic reticulum related apoptosis in HL-60 leukemic cells

  • Published:
The Chinese-German Journal of Clinical Oncology

Abstract

Objective: To investigate the anti-leukemic function of econazole (Ec), an azole anti-fungal drug. Methods: We compared efficacy of econazole to induce apoptosis in HL-60 cells with two other known endoplasmic reticulum (ER) stress inducer thapsigargin (Tg) and tunicamycin (Tu). Results: Cells treated with Ec showed typical morphology of apoptosis following 24 h incubation, parallel to the morphological changes, the expression of molecular chaperone GRP 78 was up-regulated in all cases and the caspase 12, an ER resident caspase was activated. Conclusion: Ec induced ER stress related apoptosis in HL-60 cells; the underlying mechanisms are protein synthesis inhibition through elF2a phosphorylation and caspase 12 activation.
