Research group(s)

  • Tumour Pathology
    Head: Eniko Kallay
    Research Area: The goal of the Tumour Pathology Research Group is to understand and unveil cellular and molecular mechanisms that play a role in the prevention and pathogenesis of colorectal cancer and other chronic or malignant diseases. We are studying the role of vitamin D and dietary calcium in this process as well.

Research interests

The molecular mechanism behind the effect of vitamin D and calcium in colorectal tumourigenesis.
