(A) Principle component analysis (PCA) plot of microarray data sets
of HepaRG cells exposed for 1 h, 24 h and 24 h+72 h to 3 concentrations of
bosentan, namely IC10, IC10/4 and IC10/10, and
respective vehicle controls. (B) Venn diagram of modulated genes in
HepaRG cells exposed to different concentrations of bosentan (IC10,
IC10/4 and IC10/10) for 1 h, 24 h and 24 h+72 h (gene
selection was based on a fold change modulation > 2 when compared to
respective controls and Fisher’s p < 0.05).
