Analysis of variability in transcriptome of untreated and treated HepG2 cells. a Clustering analysis of RMA-normalized microarray data from untreated and treated HepG2 cells. The clustering analysis was conducted using complete linkage as agglomeration method and Pearson correlation as similarity measure. b Correlation analysis of the three treatment conditions and the untreated HepG2 cells. The Pearson correlation coefficient between each treatment or untreated condition was estimated, as indicated in the table. All correlation coefficients were close to the possible maximum of 1 demonstrating a high overall similarity of the samples
