UNLABELLED Drug-induced liver injury (DILI) is an important clinical problem. It involves crosstalk between drug toxicity and the immune system, but the exact mechanism at the cellular hepatocyte level is not well understood. Here we studied the mechanism of crosstalk in hepatocyte apoptosis caused by diclofenac and the proinflammatory cytokine tumor(More)
Drug-induced liver injury (DILI) is an important clinical problem. Here, we used a genomics approach to in detail investigate the hypothesis that critical drug-induced toxicity pathways act in synergy with the pro-inflammatory cytokine tumor necrosis factor α (TNFα) to cause cell death of liver HepG2 cells. Transcriptomics of the cell injury stress response(More)
Cisplatin-induced nephrotoxicity is an important limiting factor for cisplatin use. Tumor necrosis factor-α (TNF-α) is known to contribute to cisplatin-induced nephrotoxicity by inducing an inflammatory process aggravating the primary injury, thereby resulting in acute kidney injury (AKI). The present study investigates the pathways synergistically(More)
Nuclear entry and exit of the NF-κB family of dimeric transcription factors plays an essential role in regulating cellular responses to inflammatory stress. The dynamics of this nuclear translocation can vary significantly within a cell population and may dramatically change e.g. upon drug exposure. Furthermore, there is significant heterogeneity in(More)
Chemotherapy often relies on cancer cell death resulting from DNA damage. The p53 tumor suppressor pathway that is an important player in DNA damage response is frequently inactivated in cancer. Genotoxicants also activate DNA damage-independent stress pathways and activity of oncogenic signaling and adhesive interactions with the cancer microenvironment(More)
Drug-induced liver injury (DILI) is an important problem both in the clinic and in the development of new safer medicines. Two pivotal adaptation and survival responses to adverse drug reactions are oxidative stress and cytokine signaling based on the activation of the transcription factors Nrf2 and NF-κB, respectively. Here, we systematically investigated(More)
Cis-diamminedichloroplatinum(II) (cisplatin)-induced renal proximal tubular apoptosis is known to be preceded by actin cytoskeleton reorganization, in conjunction with disruption of cell-matrix and cell-cell adhesion. In the present study, we show that the proinflammatory cytokine tumor necrosis factor α (TNF-α) aggravated these cisplatin-induced F-actin(More)
