Fig. 1From: Quantitative analyses of the hepatic proteome of methylmercury-exposed Atlantic cod (Gadus morhua) suggest oxidative stress-mediated effects on cellular energy metabolismHierarchical clustering (a) and principal component analysis (PCA) (b) of proteins differentially regulated by MeHg. Rows represent log2-transformed abundance ratio values of proteins, while columns represent individual cod liver samples (a). Three-dimensional PCA of normalised LC-MS/MS data (b). Individual samples are labelled according to the experimental group that they belong to; green circles: controls; yellow squares: 0.5Â mg/Kg BW (LD); red-brown triangles: 2.0Â mg/Kg BW (HD) (a and b)Back to article page
