Characterization of protein corona on AuNP surface. (Top) Effects of ethanol exposure on composition of corona proteins. (Bottom left) Chromatographic separation of peptides extracted from ethanol-negative cells. (Bottom right) Chromatographic separation of peptides extracted from ethanol-positive cells. Protein identification: 1: alcohol dehydrogenase, 2: cAMP/cGMP phosphodiesterase, 3: Tyr phosphatase, 4: transferrin, 5: glutamate CoA phosphodiesterase, 6: arginine N-methyltransferase, 7: casein kinase, 8: MAPK kinase-9, and 10: parvalbumin. C0: control cells, C16: control cells exposed for 16 days; ADH: alcohol dehydrogenase; cAMP: cyclic adenosine dinucleotide mono phosphate; cGMP: cyclic guanine dinucleotide mono phosphate; MAPK: mitogen activated protein kinase; CPS: cAMP/gAMP phosphodiesterase.
