The Nem1-Spo7/Pah1 phosphatase cascade largely controls whether phosphatidate is partitioned into the storage lipid triacylglycerol or into membrane phospholipids. The regulated synthesis of the lipids is crucial for diverse physiological processes during …Introduction. Despite widespread dissemination of the Fredrickson Levy and Lees classification scheme for lipoprotein disorders among medical school curriculums, routine clinical care does not include such phenotyping for lipoprotein abnormalities. 1 In 2008, Sniderman and others sought to reinvigorate this charge by proposing a more clinically accessible scheme for the classification of lipid ...Familial hypercholesterolemia (FH) is a prevalent but often underdiagnosed monogenic disorder affecting lipoprotein metabolism, and genetic testing for FH has not been widely conducted in Asia in the past.

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.In this short review, we first consider lipid signaling from this traditional viewpoint, highlighting innumerable Journal of General Physiology publications that have contributed to our present understanding. We then switch to our own emerging view that much important lipid signaling occurs via the formation of membrane domains that influence ...

The reason there is not stronger advocacy in guidelines for routine apoB testing is the added analytic cost to patients and the healthcare system.
