Figure 5. Effects of luteolin (100 µM), quercetin (100 µM), and ezetimibe (20 µM) on cholesterol uptake by HEK293T cells.

HEK293T cells were preincubated with flavonoids or ezetimibe at 37°C for 1 h and were washed out before the cholesterol uptake assay. Then, the cholesterol micelles were added, and their uptake was quantified to measure radioactivity. Values are mean ± standard error (n = 3). Statistical analyses were performed using Dunnett's multiple comparison test. Different letters indicate significant differences; P<0.05.
