The course is offered to students of any study field.
Course objectives
At the end of the course students should be able to understand the principles of modulations of physiological processes in organism by xenobiotics. They should be able to make deductions based on the acquired knowledge in xenobiochemistry, toxicology and pharmacology, in order to interpret physiological mechanims underlying the effects of toxic compounds and pharmaceuticals within organisms. At the end of this course, students should have a basic understanding of metabolism of xenobiotics within organism including the effects of xenobiotics at both cellular and organismal levels, impact of xenobiotics on endocrine regulation and development and 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.
