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 ...
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.

All of these lipid-sensing receptors heterodimerize with the retinoid X receptor (RXR) to activate a feed-forward metabolic cascade that maintains nutrient lipid homeostasis by governing the ... The 3-phosphoinositide-dependent protein kinase 1 (PDK1), is considered the master upstream lipid kinase of the PI3K-Akt cascade. PDK1 functions to phosphorylate and partially activate Akt, triggering the activation of downstream effectors. However, the role of PDK1 in osteoclasts has yet to be clearly defined.

This fundamental and conserved mechanism is based on an excess of ROS which attacks biomembranes, propagates lipid peroxidation chain reactions, and subsequently induces different types …
The need to coordinate this entire lipid-based metabolic signaling cascade raises important questions regarding the mechanisms that govern these pathways.
Background. The signal that starts the MAPK/ERK pathway is the binding of extracellular mitogen to a cell surface receptor.This allows a Ras protein (a Small GTPase) to swap a GDP molecule for a GTP molecule, flipping the "on/off switch" of the pathway. The Ras protein can then activate MAP3K (e.g., Raf), which activates MAP2K, which activates MAPK.Finally, MAPK can activate a transcription ...
