Materials and Methods: Effect of LUT on cell growth was assessed with water-soluble tetrazolium 1 (WST-1) cell proliferation assay and automated hemocytometry on trypan blue-exclusion assay. Cell death was investigated with acridine orange/ethidium bromide live-dead assay, propidium iodide (PI) flow cytometry, and Annexin-V-PI microscopy. Caspase activation was studied using CellEvent Caspase-3/7 Green detection reagent. High resolution immunofluorescence microscopy was used to detect cleaved-PARP-1. Results: LUT induced a dose-dependent decrease in the growth of KMH2 and L428 cells, cellular models of mix-cellularity (MC) and nodular sclerosis (NS) cHL, respectively. However, LUT induced cell death only in KMH2, at a higher concentration, and this was associated with caspase activation and cleaved PARP-1. Conclusion: LUT induces cytotoxicity in the MC-cHL cellular model KMH2 via caspase activation. ER -
