In a recent study, we investigated the protein expression changes in HepG2 cells exposed to three well-characterized model compounds (acetaminophen [APAP], amiodarone, and cyclosporin A)(Van Summeren et al., 2011). In a Letter to the Editor, Jaeschke et al. gave their comments on our study, especially with respect to the suitability of HepG2 cells to study liver toxicity, thereby limiting their comments to effects induced by APAP. We are pleased that our research opens the discussion on the use of HepG2 cells and omics technologies in toxicity screening.The major aim of our research program is to develop in vitro methods or short-term in vivo methods for testing the organotoxic properties of compounds as an alternative to the chronic rodent toxicity assays for long-term toxicity. For that, we consider several in vitro models, namely, HepG2 cells (Staal et al., 2006; Van Summeren et al., 2011), HepaRG cells (Jennen et al., 2010), as well as mouse, rat, and human primary hepatocytes (Kienhuis et al., 2009a; Mathijs et al., 2009). Ideally, in vitro models should represent in vivo conditions as good as possible; in predictive toxicology, it is emphasized that cellular models should be metabolic competent, thus express relevant phase I and II enzymes (although it is fair to note that the eventual toxic outcome is determined by a much wider range of molecular mechanisms involved). Metabolic competent, however, means that the enzymes should be expressed at a certain level so that they can activate xenobiotic compounds; it does not necessarily imply that enzymatic activities should be similar to in vivo. In contrast to the statement of Jaeschke et al., it has been shown that HepG2 cells are able to metabolize xenobiotic compounds leading to toxic effects, including genotoxicity oxidative stress and mitochondrial dysfunction (Hewitt and Hewitt, 2004; Knasmuller et al., 2004; O’Brien and Haskins, 2007; Schoonen et al., 2009). However, it is undeniable that the HepG2 cells have lost some of the liver-specific functions
