Chemical-DNA adducts provide an integrated measure of exposure, absorption, bioactivation, detoxification, and DNA repair following exposure to a genotoxic agent. Benzo[a]pyrene (BaP), a prototypical polycyclic aromatic hydrocarbon (PAH), can be bioactivated by cytochrome P-450s (CYPs) and epoxide hydrolase to genotoxic metabolites which form covalent adducts with DNA. In this study, we utilize...
Cardiac tissue slices are becoming increasingly popular as a model system for cardiac electrophysiology and pharmacology research and development. Here, we describe in detail the preparation, handling, and optical mapping of transmembrane potential and intracellular free calcium concentration transients (CaT) in ventricular tissue slices from guinea pigs and rabbits. Slices cut in the epicardiu...
AIMS Cardiovascular research requires complex and functionally intact experimental models. Due to major differences in the cellular and subcellular composition of the myocardium between species, the use of human heart tissue is highly desirable. To enhance the experimental use of the human myocardium, we established methods for the preparation of vital tissue slices from the adult ventricular m...
Precision-cut slices of in vivo tumours permit interrogation in vitro of heterogeneous cells from solid tumours together with their native microenvironment. They offer a low throughput but high content in vitro experimental platform. Using mouse models as surrogates for three common human solid tumours, we describe a standardised workflow for systematic comparison of tumour slice cultivation me...
