Area of Science:

  • Toxicology
  • Biomarker Discovery
  • Molecular Toxicology

Background:

  • Biomarkers are increasingly vital in toxicology.
  • Understanding exposure and toxic responses is key.
  • Individual variability influences toxicological outcomes.

Purpose of the Study:

  • To provide an overview of current biomarker applications in toxicology.
  • To highlight novel developments in exposure and response biomarkers.
  • To discuss biomarkers for susceptibility.

Main Methods:

  • Review of existing literature on biomarkers.
  • Discussion of DNA and protein adducts for exposure assessment.
  • Analysis of urinary metabolite profiles using Nuclear Magnetic Resonance (NMR).

Main Results:

  • DNA and protein adducts serve as effective exposure biomarkers.
  • NMR-based urinary metabolite profiling identifies novel response biomarkers.
  • Specific urinary markers for liver and testicular dysfunction were identified.

Conclusions:

  • Biomarkers significantly advance toxicological assessments.
  • Novel methods enable precise measurement of exposure and response.
  • The acetylator phenotype is a key biomarker for susceptibility.
