Consistent with the lipid metabolic cascade model, two xenobiotic transporters, ABCB1 (or MDR1) and ABCC2 (or MRP2), are up-regulated in hepatocytes and intestinal cells by SXR activators and chemotherapeutic agents, such as Taxol (58, 59). Thus, this part of the regulatory circuit plays an important role in drug resistance.The roles of lipid rafts within the metastatic cascade, specifically within tumor angiogenesis, cell adhesion, migration, epithelial-to-mesenchymal transition, and transendothelial migration are highlighted.
