Peroxynitrite and 4-Hydroxynonenal Inactivate Breast Cancer Resistance Protein/ABCG2

<div>Effect of peroxynitrite (PN) on uptake of riboflavin into<i> Sf9</i>-BCRP/ABCG2 membrane vesicles, expressed as pmol riboflavin/mg protein/min. Data are mean ± SD from 3-4 determinations. (a) BCRP-mediated transport of riboflavin in the presence of 50 <i>μ</i>M of PN (filled symbols) vs. control (open symbols); (b) inhibition of riboflavin uptake by peroxynitrite (PN).</div>
