This panel is useful in the detection, classification, and monitoring of hyperlipidemia, especially those expected to have highly elevated TG levels. LDL-C is widely accepted as a key factor for assessing the risk of coronary artery disease (CAD) [1]. 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.Lipid metabolic reprogramming is an emerging mechanism of resistance to kinase inhibitor therapy in breast cancer.
