Drug transporters in spermatogenesis
Drug transporters are integral membrane proteins expressed by a variety of organs, including the liver, kidney, small intestine and testis, and they are generally known to mediate drug or xenobiotic transport into and out of cells. Previous studies have also reported the presence of several drug transporters at blood-tissue barriers where they are thought to protect organs from harmful agents. ...
متن کاملDrug conjugation in clinical toxicology.
Conjugation is an important mechanism for the rapid inactivation and extensive removal of drugs and poisons from the body, and as such it is of major significance in clinical toxicology. The capacity for conjugation of some drugs is large, but with others, saturation may occur with overdosage or even high therapeutic doses. Glutathione conjugation is an important mechanism of protection against...
متن کاملDrug and Chemical Toxicology
In the present study, the genotoxic effects of the low-calorie sweetener aspartame (ASP), which is a dipeptide derivative, was investigated using chromosome aberration (CA) test, sister chromatid exchange (SCE) test, micronucleus test in human lymphocytes and also Ames/Salmonella/ microsome test. ASP induced CAs at all concentrations (500, 1000 and 2000 mg/ml) and treatment periods (24 and 48 h...
متن کاملHepatobiliary transporters in the pharmacology and toxicology of anticancer drugs.
The existence of carrier proteins located in the basolateral and apical membranes of hepatocytes, cholangiocytes and epithelial cells of the ileal mucosa, together with their more or less broad substrate specificities -implying their ability to transport many different drugs, including anticancer drugs- has important pharmacological repercussions. These vary from the existence of interactions o...
متن کاملToxicology and Adverse Drug Reactions
Toxicology has two main goals in relation to adverse drug reactions (ADRs). The first is to identify and characterize the potential for harmful effects that can be produced in biological systems, particularly laboratory animals, by a drug, and to suggest therapeutic circumstances in which toxic responses may occur and/or are unlikely to occur. The second is necessary when unexpected adverse cli...
