Anti-leukemic activity of Cyperus rotundus L. on human acute myeloid leukemia HL-60 cells in vitro

Context: Acute myeloid leukemia (AML) is the most common form of acute leukemia. Currently, many people use medicinal herbs for the treatment of cancers. Nut grass (Cyperus rotundus L.) is a medicinal plant widely used in conventional medicine due to its role as an anti-cancer. Aims: To evaluate the effect of Cyperus rotundus tuber (CRT) ethanolic extract on cell proliferation, differentiation, cell cycle, and apoptotic of HL-60 cells. Methods: HL-60 cells line as a model for AML was cultured under the influence of CRT extract concentrations (35.4, 354, and 3540 µg/mL) for 48 h. Furthermore, the cell was subjected to carboxyfluorescein succinimidyl ester staining for proliferation, using a CD117 marker for differentiation. Annexin V-FITC and PI for cell cycle and apoptosis. The effect of this herb was studied by flow cytometry. The data were statistically analyzed with one-way ANOVA (p≤0.05) and the Tukey test using SPSS version 16 for Windows. Results: The results showed that the CRT inhibited proliferation activity, differentiation, cell cycle arrest, and apoptosis. Conclusions: The data clearly showed the potential anti-cancer activity of CRT on HL-60 cells and suggested that it could help develop promising therapeutic agents for AML treatments. © 2023 Journal of Pharmacy & Pharmacognosy Research.
