Fig. 7From: Assessment of Gold Nanoparticles-Inhibited Cytochrome P450 3A4 Activity and Molecular Mechanisms Underlying Its Cellular Toxicity in Human Hepatocellular Carcinoma Cell Line C3AA schematic representation of the basic mechanisms of action of 40 nm PEG-AuNP in HCC treatment. Green bars (an inhibition) and pink triangles (an induction) indicate the 40 nm PEG-AuNP-modified biological markers and pathways.
