Quercetin causes apoptosis of RB Y79 cells in vitro. a The control cells (untreated), the treated cells received various concentration of Quercetin (0-100 μM) for 24 h. Extent of apoptotic cells were assessed by flow cytometry subjecting cells to staining of propidium iodide (PI) and Annexin V-fluorescein isothiocyanate (FITC). b Results represent analysis of the total apoptotic cell population. All the data presented are the means ± SD (n = 3). *P < 0.05, **P < 0.01 against control. c Quercetin caused ΔΨm collapse in cancerous RB Y79 cells. Flow cytometric analysis was done in order to record the mean fluorescence intensity (MFI) of DiOC6. All the values are the means ± SD (n = 3). *P < 0.05, **P < 0.01 against control
