Main research topics

  • Effects of specific integrin-mediated cell adhesion on the tumor biological behaviour of human ovarian and breast cancer cells
  • Differential gene expression in human cancer cells as a function of integrin αvβ3 expression
  • Interaction of integrins with other cell surface receptors and signaling molecules (e.g. epidermal growth factor receptor, integrin-linked kinase)
  • Characterisation of the role of the putative tumor suppressor ADAM15 in human ovarian cancer cells and its functional interaction with integrin αvβ3
  • Characterisation of the role of the tetraspanin and tumor suppressor KAI1 (CD82) in concert with integrin αvβ3 in human ovarian and breast cancer cells
  • Investigation of molecular mechanisms and conformational changes during integrin activation and integrin-mediated signal transduction
  • Development, screening, and testing of specific integrin antagonists for therapeutical intervention
  • Determination of integrin αvβ3 binding parameters to extracellular matrix proteins and synthetic (antagonistic) integrin ligands by surface plasmon spectroscopy on integrin-functionalized artificial phospholipid membranes
  • Integrin/ligand binding assays using cell-free in vitro synthesized integrins on polymeric vesicular membrane architectures
  • Isolation of circulating tumor cells from the blood of cancer patients by use of an antibody-functionalized nanodetector
