Understanding Coenzyme Q
Physiol Rev. 2024 May 9. doi: 10.1152/physrev.00040.2023. Online ahead of print.ABSTRACTCoenzyme Q (CoQ), also known as ubiquinone, comprises a benzoquinone head group and a long isoprenoid sidechain. It is thus extremely hydrophobic and resides in membranes. It is best known for its complex function as an electron transporter in the mitochondrial electron transport chain (ETC) and in several other cellular processes. In fact, CoQ appears to be central to the redox balance of the cell. Remarkably, its structure and properties have not changed from bacteria to vertebrates. In metazoans, it is synthesized in all cells and is...

A versatile delivery vehicle for cellular oxygen and fuels, or metabolic sensor? - A review and perspective on the functions of myoglobin
Physiol Rev. 2024 May 2. doi: 10.1152/physrev.00031.2023. Online ahead of print.ABSTRACTA canonical view of the primary physiological function of myoglobin (Mb) is that it is an oxygen (O2) storage protein supporting mitochondrial oxidative phosphorylation, especially as the tissue O2 partial pressure (pO2) drops and Mb offloads O2. Besides O2 storage/transport, recent findings support functions for Mb in lipid trafficking and sequestration, interacting with cellular glycolytic metabolites such as lactate (LAC) and pyruvate (PYR) , and "ectopic" expression in some types of cancer cells and in brown adipose tissue (BAT). Da...

Neuronal glucose sensing mechanisms and circuits in the control of insulin and glucagon secretion
Physiol Rev. 2024 Apr 25. doi: 10.1152/physrev.00038.2023. Online ahead of print.ABSTRACTGlucose homeostasis is mainly under the control of the pancreatic islet hormones insulin and glucagon, which, respectively, stimulate glucose uptake and utilization by liver, fat, and muscle or glucose production by the liver. The balance between the secretion of these hormones is under the control of blood glucose concentrations. Indeed, pancreatic islet b-cells and a-cells can sense variations in glycemia and respond by an appropriate secretory response to restore euglycemia. However, the secretory activity of these cells is also und...
