Early stage researcher 13 (ESR13) project
Supervision: Prof. Dr. Federico Mayor Jr., Prof. Dr. Petronila Penela
I - Project proposal:
- Investigate signalling network signatures (phosho-protein barcodes, signalling pathways, cell acetylome, secretome) upon CXCL12-induced migration and proliferation via CXCR4 and/or ACKR3 in model breast and colon cancer cell lines. Influence of GRK2 dosage and of co-stimulation of relevant RTK and modulation by small molecule inhibitors or CXCR4/ACKR3, RTK nanobodies.
- Analyse effects of CXCR4/ACKR3/GRK2 inhibition (via nanobodies, small molecule inhibitors) on in vivo metastatic potential of breast cancer cells or colon cancer Cell signalling techniques, Co-ip and confocal microscopy in cell models, 2D and 3D migration/invasion assays, XCell-based adhesion and proliferation assays, in vivo tumor models in mice
Cell signalling techniques, Co-ip and confocal microscopy in cell models, 2D and 3D migration/invasion assays, XCell-based adhesion and proliferation assays, in vivo tumor models in mice
Universitätsklinikum Jena – Use of sensors to investigate early events in GRK2 and beta-arrestin dynamics/recruitment upon CXCL12-induced CXCR4 and/or ACKR3 receptor activation in model HEK293 cells
Vrije Universiteit Amsterdam – Validate use CXCR4/ACKR3 nanobodies for in vivo use
