Although pro-opiomelanocortin (POMC) is a well-known hormone precursor in many species, molecular information about avian POMCs is still relatively scarce. In a former study (Berghman et al., [1998] Mol Cell Endocrinol. 142:119-130) the nucleotide and amino acid sequence of N-terminal POMC in the chicken were reported. To complete the nucleotide sequence of(More)
Assessing the potential of a new drug to cause drug-induced liver injury (DILI) is a challenge for the pharmaceutical industry. We therefore determined whether cell models currently used in safety assessment (HepG2, HepaRG, Upcyte and primary human hepatocytes in conjunction with basic but commonly used endpoints) are actually able to distinguish between(More)
Although, since the isolation of pituitary adenylate cyclase-activating polypeptide (PACAP), a wealth of literature has been published describing its localization, binding sites, and biological activities in a variety of mammalian tissues, only very little is known about PACAP in avian species. Therefore, in order to find out the sites of actions of PACAP(More)
The use of label-free technologies based on electrical impedance is becoming more and more popular in drug discovery. Indeed, such a methodology allows the continuous monitoring of diverse cellular processes, including proliferation, migration, cytotoxicity and receptor-mediated signaling. The objective of the present study was to further assess the(More)
The current test systems employed by pharmaceutical industry are poorly predictive for drug-induced liver injury (DILI). The ‘MIP-DILI’ project addresses this situation by the development of innovative preclinical test systems which are both mechanism-based and of physiological, pharmacological and pathological relevance to DILI in humans. An iterative,(More)
To map in detail the brain areas in which pituitary adenylate cyclase-activating polypeptide (PACAP) may play a significant role in birds, the distribution of PACAP and PACAP type I receptor (PAC(1)-R) mRNA was examined throughout the entire chicken brain by using in situ hybridization histochemistry. Widespread distribution of both PACAP and its receptor(More)
