Ad-siRadixin altered the localization of apical bile transporters in hepatocytes. Hepatocytes were treated with PBS, Ad-siControl or Ad-siRadixin and cultured for 5 days. Cells were double labeled with anti-Mrp2 and anti-Bsep antibodies (top 2 rows), with anti-Mdr1 (third row), or anti-Oatp2 antibodies (bottom row). Note that all three apical membrane transporters, but not the basolateral membrane protein, showed significant intracellular localization in knock down areas after Ad-siRadixin treatment.
