Abc Transporters 40 Years On

This book provides new structural, biochemical, and clinical information on ABC transporters. The authors explore and describe the state of the art of research, knowledge, and prospects for the future for this important family of proteins. The first ABC transporter was discovered in 1973 and was named P-glycoprotein. It elicits resistance to cytotoxic drugs, chiefly in human tumours, within which chemotherapy failure is observed in about 50% of cases. Together with its complex pharmacology, and even a suspected role in Alzheimer’s disease, this ABC transporter still eludes a clinical solution to its multidrug resistance property. ABC transporters are integral membrane active proteins and they belong to one of the largest protein families across all species. Their myriad roles encompass the import or export of a diverse range of allocrites, including ion, nutrients, peptides, polysaccharides, lipids, and xenobiotics. They are of major medical importance with many members elaborating multidrug resistance in bacteria, fungi, yeast, parasites, and humans. Other ABC transporters are involved in a number of inherited diseases, including cystic fibrosis, macular degeneration, gout, and several other metabolic disorders

This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.

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.
