This book was released on 2022-01-12 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around one third of all biologically relevant small molecules are organic cations. These include endogenous substances like catecholamines and other neurotransmitters, toxins and drugs designed to affect signaling processes. The organic cation transporter 1 (OCT1) is among the strongest expressed membrane transporters at the sinusoidal (blood-facing) side of liver cells and contributes substantially to the clearance of the blood from numerous organic cations. A most striking feature of OCT1 is its pronounced genetic diversity. Between 1 and 10% of all human populations have little to no OCT1 activity. With several of the OCT1 substrates up to 10% of Europeans are functionally OCT1 deficient. Apparently, the lack of OCT1 do not lead to apparent substantial pathological changes in these individuals. It thus appears that this transporter is not essential to human life, but does it means that OCT1 is irrelevant? In the last 25 years since the first cloning of this transporter, data on its pharmacological and physiological relevance is steadily accumulating. Numerous clinically relevant drugs (e.g. metformin, morphine, fenoterol, sumatriptan, tramadol and tropisetron) have been shown to be substrates of OCT1, and OCT1 deficiency has been shown to affect the pharmacokinetics, efficacy, or toxicity of these drugs. Also vitamin B1 has been shown to be a substrate of OCT1, and in genetically modified mice OCT1 substantially modulated hepatic lipid metabolism, total body fat and systemic glucose and lipid concentrations. Still, numerous important questions remain unsolved: For which drugs, toxins, or other endogenous or exogenous substances is OCT1 relevant? How can we predict the relevance of OCT1 from in vitro studies? What determines the substrate selectivity of OCT1 in comparison to other transporters or transport processes for organic cations? What regulates the expression of OCT1 in the liver and possibly in other tissues? What is the impact of OCT1 variation in different areas of medicine, including the therapies for cancer as well as for pulmonary, cardiovascular, or neurological diseases? How can evolutionary biology contribute to a better understanding of the roles of OCT1? And, importantly, what types of research are likely to significantly further the knowledge on OCT1 in the next decades?

This book was released on 2021 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane transporters are of vital importance for cells. They mediate the flux of many substances through the plasma membrane. In this book, the transporters for organic cations, a special class of membrane transporters, are presented. Transporters belonging to this class are important because they allow many neurotransmitters (e.g., histamine and serotonin) and many drugs (e.g., trospium and tofacitinib) to permeate the plasma membrane. Therefore, transporters for organic cations can modulate the action of neurotransmitters and drugs, having in this way important physiological and pharmacological implications. These aspects are illustrated in original works and reviews presented in this book. Using a system biology approach, the global significance of different transporters working together has been illustrated. Regulation mechanisms determining their expression in specific organs and modulating their function are also described in this book, also concerning their role for special drug toxicities. Such an aspect is also discussed in relationship to mutations (single nucleotide polymorphisms) of transporters for organic cations. Finally, the translational value of studies performed in flies, mice, and rats is discussed. Therefore, this book offers integrative information on transporters for organic cations, which may be of interest to beginners and specialized scientists in this field.
