Data analysis from the 2D gel-based approach - Identified molecular networks using Ingenuity IPA. a) 24 h and b) 72 h experment. The table reports the most significant molecular networks in response to 1 and 10 μg/mL AgNP treatments, by analysing the differentially expressed proteins from the cells. The network number, the list of all proteins and metabolites involved in the network, the number of molecules overlapping between our data set and the network and the top functions related to the network are shown. Focus molecules are indicated in bold and deregulation is indicated with a coloured arrow (red: up-regulated, green: down-regulated).
