Course objectives
This course should provide students with principles of modulations of physiological processes in organism by xenobiotics. The main goal is to connect the current state of knowledge in xenobiochemistry, toxicology and pharmacology with animal physiology so that it would enable to deepen the understanding of students to both mechanisms of action of xenobiotics and their consequences for both individuals and populations. At the end of this course, students should have a basic understanding of metabolism of xenobiotics within organism; effects of xenobiotics at both cellular and organismal levels; impact of xenobiotics on endocrine regulation and development; basic types of toxic effects of xenobiotics.
Syllabus
  • 1)An overview of chemical compounds that may disrupt normal physiological functions - anthropogenic organic pollutants, pharmaceuticals, secondary metabolites (dietary compounds and toxins); main exposure routes.
  • 2)Basic principles of metabolization, transport and accmulation of xenobiotics within body, Phase I and II biotransformation enzymes; antioxidants;Phase III. proteins.
  • 3)Basic types of toxicity of xenobiotics (genotoxicity, hepatotoxicity, neurotoxicity, immunotoxicity, tumor promotion, endocrine disruption).
  • 4)Basic classes of pharmaceuticals, pharmacokinetics, toxic side-effects of pharmaceuticals; cytostatics, hormones, neuroleptic compounds.
  • 5)Deregulation of signal transduction by xenobiotics.
  • 6)bHLH/PAS protein family; HIF-1alpha, Ah receptor and its pathway; toxic effects of AhR ligands.
  • 7)Nuclear receptors (ER, AR, PR, GR, TR, RAR/RXR, CAR, PXR, PPAR) their ligands; their role in regulation of metabolism; physiological functions based on modulation of target gene expression.
  • 8)Biosynthesis and metabolism of endogenous NR ligands (steroids, fatty acids, lipid mediators); hormonal regulation of biosynthesis.
  • 9)Principles of hormonal regulation and endocrine disruption in invertebrates.
  • 10)Endocrine regulation and disruption in vertebrates: ER, AR, PR, GR.
  • 11)Endocrine disruption and regulation of embryonal and post-natal development of vertebrates: RAR, RXR, PPAR, TR.
  • 12)Natural compounds; sources and chemoprotectivity.
