The effect of BPA on micellar cholesterol absorption in Caco-2 cells. a Time-dependent effect of BPA on cholesterol absorption in Caco-2 cells. The cells were pretreated with 10 nM BPA for different time, and then incubated with radioactive micellar cholesterol for 2 h. b Dose-dependent effect of BPA on cholesterol absorption in Caco-2 cells. The cells were pretreated with BPA at different concentrations for 24 h, and then incubated with radioactive micellar cholesterol for 2 h. The absorption of cholesterol was determined and that in the absence of BPA was taken as 100%. Results are mean ± SEM from triplicate determinations in three separate experiments. *P < 0.05 compared to untreated cells (Control)
