Expression of membrane transporters of organic anions and cations, glucose, hydrogen ions and water in kidneys and other organs of laboratory animals (mice, rats), pigs and humans:

  • Sex and species specific differences in transporter expression
  • Regulation of transporter expression with sex hormones at the level of mRNA and/or proteins
  • Regulation of transporter expression by intracellular vesicular transport; the role of cytoskeleton
  • Relationship between transporter expression and (re)absorption and/or secretory organ functions

Experimental toxicity of some heavy metals (cadmium, mercury, lead):

  • Mechanism of toxicity of heavy metals in cells along the rat nephron
  • Role of metallothionein as mediator and/or protector against toxicity induced by heavy metals
  • Role of cell membrane transporters in the transport and toxicity of heavy metals
  • Effect of toxic metals on:
    • structure and function of cytoskeleton
    • intracellular vesicular transport
    • expression of cell membane transporters in mammalian kidneys and liver

Physiology, pathophysiology and toxicology of hydrogen ion transporters in male and female reproductive system:

  • Hydrogen ion transporters in cells along the male and female reproductive systems in rats and humans
  • Morphological and functional features of cells excreting hydrogen ions in the reproductive system in experimental toxicity induced by heavy metals in male and female rats
