Abstract: Our research focuses on therapeutic strategies aiming to exploit oncogene-induced vulnerabilities and we have had a long-term interest especially in the apoptotic function of MYC protein. Our group recently discovered a clinically applicable combination regimen, which shows a strong apoptotic activity selectively in MYC-high breast tumors in all preclinical models tested so far.
My talk will cover our advances in translating the biological understanding of MYC biology into new type of therapeutic modalities to battle the breast cancer.
A key asset in our research involves patient-derived explant culture models (PDEC) of breast cancer. We have pioneered the development of PDEC models and we have recently generated a whole family of PDEC models to explore for instance the biology of hormone receptor positive breast cancers, metastatic breast cancer microenvironment and drug resistance and possible ways to overcome. Furthermore, we have established a platform for PDECs with natural tumor infiltrating leukocytes to explore the immuno-oncology targeted drug responses. My talk will cover the latest developments in our work with PDEC models of breast cancer with specific focus on MYC-dependent signaling as a major cause of targetable vulnerabilities in breast cancer.
