The organic anion transporter 5 (Oat5, Slc22a19) was previously localized to the brush-border of proximal tubule (PT) S3 segment in rat and mouse kidneys. Here we report on sex hormone-regulated expression of Oat5 in rat kidneys, after reinvestigating: a) expression of its mRNA by end-point and real time RT-PCR in the tissue, b) abundance of its protein by Western blotting (WB) in isolated membranes, and c) immunolocalization in tissue cryosections. In untreated male (M) and female (F) adult rats, the expression of Oat5 mRNA was predominant in the outer stripe (OS), exhibiting sex differences (M
