Download or read book Organic Cation Transporter 1 OCT1 Not Vital for Life but of Substantial Biomedical Relevance written by Jurgen Brockmoller and published by Frontiers Media SA. 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?

Download or read book Drug Transporters in Drug Disposition Effects and Toxicity written by Xiaodong Liu and published by Springer Nature. This book was released on 2019-09-30 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides with a comprehensive overview of the role of drug transporters in drug disposition and efficacy/toxicity, as well as drug-drug interactions and recent advances in the field. Transporters are known determinants of drug disposition and efficacy/toxicity. In general, they are divided into solute carrier (SLC) and ATP binding cassette (ABC) families, and are located along cell membranes, where they mediate drug uptake into cells and export out of cells. Drug transporters are essential in maintaining cell homeostasis, and their gene mutations may cause or contribute to severe human genetic disorders, such as cystic fibrosis, neurological disease, retinal degeneration, anemia, and cholesterol and bile transport defects. Conversely, some diseases may also alter transporter functions and expressions, in turn aggravating disease process. Further, since over-expression of some ABC transporters is a potential contributor to multidrug-resistance (MDR), the book presents a number of strategies to overcome MDR, including ABC transporter inhibitors and applying epigenetic methods to modulate transporter expressions and functions. This book is useful for graduate students and professionals who are looking to refresh or expand their knowledge of this exciting field.
