1 Cytotoxicity of paclitaxel in OVCAR-3, SK-OV-3 and OATP1B1- and OATP1B3-transfected SK-OV-3 cells was performed using the CellTiter-Glo assay. Paclitaxel solute carrier organic anion transporter family member 1B1 Homo sapiens
2 The higher mRNA levels for OATP1B1 and OATP1B3 found in SK-OV-3 cells correlated with higher initial uptake rates for paclitaxel. Paclitaxel solute carrier organic anion transporter family member 1B1 Homo sapiens
3 CONCLUSIONS: Our results revealed OATP1B1 and OATP1B3 as high-affinity paclitaxel transporters expressed in ovarian cancer cell lines and tumor tissues, suggesting a role for these polypeptides in the disposition of paclitaxel during therapy. Paclitaxel solute carrier organic anion transporter family member 1B1 Homo sapiens
