The effect of extract from aerial parts of Juniperus excelsa plant on proliferation and apoptosis of acute lymphoblastic leukemia cell lines, Nalm-6 and Reh

Background and ObjectivesAcute lymphoblastic leukemia (ALL) is the most common childhood malignancy. The side effects of chemotherapeutic drugs have primarily lead to the increased use of natural products for cancer treatment. Juniperus excelsa, a medicinal herb, was reported to show antiproliferative effects on various cancer cells. In this study, cytotoxic and apoptotic effects of extract from aerial parts of Juniperus excelsa plant were investigated on acute lymphoblastic leukemia cell lines, Nalm-6 and Reh.
Materials and MethodsIn this basic research, Nalm-6 and Reh were cultured and then they were treated with various concentrations of J. excelsa extract for 48 and 72 h and then the cell viability was evaluated by using MTT assay. Apoptosis also was assessed by caspase 3 activity assay and flow cytometry following Annexin V and Propidium iodide staining. Statistical analysis was assessed by one-way ANOVA test and SPSS 23.
ResultsMTT assay results show that J. excelsa extract concentrations of 3, 4 and 5 µg/ml significantly reduce percentage of alive cells (p Conclusions Our study shows that extract from aerial parts of J. excelsa has cytotoxic and apoptotic effects on Nalm-6 and Reh cells.
