The Transformer database: biotransformation of xenobiotics

As the number of prescribed drugs is constantly rising, drug-drug interactions are an important issue. The simultaneous administration of several drugs can cause severe adverse effects based on interactions with the same metabolizing enzyme(s). The Transformer database (http://bioinformatics.charite.de/transformer) contains integrated information on the three phases of biotransformation (modifi...

Biotransformation of xenobiotics in human intestinal mucosa

Drug-metabolizing enzymes, especially monooxygenases, play a major role in biotransformation and detoxification of many foreign compounds including environmental carcinogens. Although largely localized in the liver they are also found in the small intestine, which is the portal of entry of dietary toxins. Therefore cytochrome P-450 content as well as monooxygenase (7-ethoxycoumarin O-deethylase...

The role of cytochrome P450 in biosynthesis of bioregulators and biotransformation of xenobiotics

Oxidative stress due to free radicals is involved in the pathogenesis of many chronic disorders including cancer, inflammation and neurological diseases. Reactive oxygen species (ROS) may be implicated in age-related macular degeneration (AMD).This study investigated the expression of manganese superoxide dismutase MnSOD on mRNA and protein level. Moreover it examines the genetic sequence polym...
