Modulation and absorption of xenobiotics: the synergistic role of CYP450 and P-gp activities in cancer and neurodegenerative disorders.

abstract：:Metabolism of xenobiotics is often seen as an exclusive function of the liver, but some current findings support the notion that the lungs, kidneys and intestine may contribute considerably. After the establishment of the use of liver slices as a useful in vitro model to study metabolism and toxicity of xenobiotics, t...
