Cytotoxic, genotoxic and apoptotic effects of naringenin-oxime relative to naringenin on normal and cancer cell lines

ABSTRACT

Objective To assess and compare the cytotoxic, genotoxic, apoptotic and reactive oxygen species (ROS) generating effects of naringenin (NG) and its new derived compound naringenin-oxime (NG-Ox) on MCF-7, HT-29, PC-12 cancer and L-929 normal cell lines. Methods The cells were incubated with different doses of NG-Ox and NG (50–1 000 μmol/L) for 24 h. The cell viability was assessed based on ATP cell viability assay. Intracellular accumulation of ROS was determined using the fluorescent probes 2'7'-dichlorodihydrofluorescin diacetate. Genotoxic effects were evaluated by alkaline single cell gel electrophoresis assay (comet assay) and, the apoptotic effect was evaluated by acridine orange staining at below the IC
