Scientific Scope

Vascularization of tumors is a prerequisite for cancer progression and requires endothelial cell migration out of existing vessels, a process called angiogenesis. Most recent studies emphasize, that blood circulating BMPs (Bone or Body Morphogenetic Proteins) regulate in a dose dependent manner angiogenesis highlighting this pro-angiogenic function as novel clinical strategies for drug developments. The underlying molecular mechanism is however not understood. In our previous studies, we have unravelled the molecular mechanism, by which BMP2 and BMP14/GDF5 induce transcriptional and non-transcriptional responses in mesenchymal precursor cells. Using proteomics based approaches, we have identified a number of receptor associated proteins, which link to novel pathways, potentially involved in the regulation of cell migration, cytoskeletal rearrangements and cell-cell contact. We aim at providing novel strategies against tumor-induced angiogenesis and for innovative cancer therapies.
