Effect of Quercetin on mRNA expression of some relevant ABC transporters (a) and on genes involved in the purinergic pathway (b). HepG2 cells were treated with Quercetin (165 μM) for 24 h. Cells treated with 0.25% DMSO were used as a control. Results are expressed as the mean and 95% confidence interval of three different experiments. Statistical analysis was performed on ΔCt values by using multiple T-test followed by Holm–Sidak correction for multiple comparisons; * p < 0.05; *** p < 0.001. Effect of Quercetin on ABCC6 (c) and NT5E (d) protein expression. Results are expressed as the mean ± the standard error of three independent experiments. Results were analyzed by Student’s t test; * p < 0.05.
