Main scientific programs are related to the investigations of:


  • expression of ghrelin and its receptors in human stomach and pancreas during prenatal and early postnatal development -relationship to other hormones
  • HER-2 and TOP2A gene status and their correlation with Bcl-2, p53, Ki67, ssDNA, and clinicopathological parameters in four molecular subtypes of breast cancer
  • role of nitric oxide in the effects of ethanol as a stressor on HPA axis and mucosal immune system
  • cellular and molecular mechanisms underlying erythropoietic response to chronic psychological stress
  • pathogenesis of hematological malignancies with special reference to angiogenesis and oxidative stress
