Human CYPs are primarily membrane-associated proteins located either in the inner membrane of mitochondria or in the endoplasmic reticulum of cells. CYPs metabolize thousands of endogenous and exogenous chemicals. Some CYPs metabolize only one (or a very few) substrates, such as CYP19 (aromatase), while others may metabolize multiple substrates. Both of these characteristics … WebAn overview of in vitro toxicology studies covering a range of techniques from cell based assays to indicators of adverse drug interactions, hERG channel inhibition and genotoxicity with mass spectrometer, fluorescence imaging and qRT-PCR endpoints.
