"Ne\u010Das, E." . "1" . . "TNF-related apoptosis-inducing ligand (TRAIL) is a proapoptotic cytokine implicated in cancer cell surveillance. Prolonged exposure of TRAIL-sensitive leukemia cell line HL60 cells to recombinant TRAIL or to cytostatic agents, cytarabine and idarubicin, resulted in the establishment of resistant subclones with distinct phenotypes. The TRAIL resistant subclones had decreased expression of TRAIL and TNFa death receptors, impaired activation of caspases 8 and 10 in response to TRAIL and TNFa and dysregulated expression of several apoptosis regulators. TRAIL resistant HL60 showed two phenotypes with different expression of CD14, osteoprotegerin, and several apoptosis regulators and were resistant to TNFa, suggesting disruption of the extrinsic apoptotic pathway. The concurrently derived cytarabine and idarubicin-resistant HL60 subclones remained sensitive to TRAIL-induced apoptosis. We identified distinct pathways for the development of HL60 leukemia cell resistance to apoptosis induction." . "1"^^ . . .
