Hotel Description

The Netherlands Toxicogenomics Centre (NTC), led by Prof. J.C.S. Kleinjans of the Department of Toxicogenomics at Maastricht University, has been initiated by the Netherlands Genomics Initiative with the particular purpose to integrate ‘omics technologies. This integration occurs at two levels:

  1. NTC applies the full breath of “wet bench” ‘omics technologies, covering analyses of whole genome gene expression, microRNA regulation and epigenomics by applying microarray technologies and next generation sequencing methods, of proteomics by means of mass spectrometry, of metabolomics by means of NMR and mass spectrometry, and of functional genomics by means of life cell imaging, in order to utilize read-outs from multiple ‘omics platforms for achieving a better and in depth understanding of molecular mechanisms underlying toxic modes-of action
  2. NTC applies a wide range of ‘dry bench” technologies comprising bioinformatics, biostatistical and visualisation techniques, to achieve the actual integration of data delivered by multiple ‘omics platforms

NTC aims at integrating multiple ‘omics technologies for the purpose of applying obtained mechanistic insight to developing non-animal-based cellular models for better predicting human toxicity, in particular chemical carcinogenesis, immunotoxicity, reproduction toxicity, neurotoxicity, intestinal toxicity and livertoxicity, thereby replacing current animal models for assessing chemical safety.

Systems biology
  • Biomedical & health
  • NTC covers both fields of life sciences technology expertise, with probably a dominant role for experimental technologies
  • In addition, to its multi-omics technologies, NTC may offer electron spin resonance techniques
  • Genetic toxicology
  • Immunotoxicology
  • Reproduction toxicology
  • Hepatic and renal toxicology
  • Neurotoxicity

Expertise and Track Record

43500985043 Decoding effects of bioactive soluble factors on transcriptional programs in mouse embryonic stem cell-based embryoid bodies using high-throughput screening platforms with S. Giselbrecht (Maastricht University).

All hardware, software and experience necessary for performing and analyzing large-scale genomics studies is available. The team of Prof. J.C.S. Kleinjans was one of the first to report on RNA-seq analysis in toxicology. Currently, ~3650 samples have been sequenced and analyzed. In the coming 3 years it is expected that this number will grow above 5650 samples.

EU-ToxRisk (http://www.eu-toxrisk.eu/) – An Integrated European ‘Flagship’ Programme Driving Mechanism-based Toxicity Testing and Risk Assessment for the 21st century – is a European collaborative project funded by the EU Framework Programme for Research and Innovation, Horizon 2020. With a budget of over 30 million €, the project started on 1st January 2016 and will last for a duration of 6 years.

BReIN (Brightlands e-Infrastructure for Neurohealth) – A multi-omics/imaging project aiming at better understanding the impact of environmental factors on Alzheimer’s  Disease. With a budget of over 20 million euro, the project started on 1st January 2019 and will last for a duration of 7 years.
