Research Summary

Aims

The overall goals of our research are: (1) to identify and molecularly characterize recurrent fusion oncogenes, mutations, and other genomic rearrangements in glandular tumors of the breast and head and neck; (2) to study the pathogenetic and clinical significance of identified drivers and based on this knowledge develop new targeted cancer therapies; (3) to elucidate the molecular pathogenesis and develop new treatment options for patients with the inherited Brooke-Spiegler tumor syndrome.

Workplan

Genomic and transcriptomic profiles and novel fusion oncogenes and mutations are identified with next generation sequencing technologies and arrayCGH. Clinical and histopathological data are collected and analyzed from all patients. The functions and molecular consequences of identified drivers are studied with molecular and cell biological techniques. Candidate drugs are identified by screening of large drug libraries using validated human tumor models followed by testing in preclinical patient-derived xenograft models and in clinical studies.

Significance

Mapping of the genomic landscape of tumors provides unique opportunities to identify novel fusion oncogenes and mutated cancer genes. Molecular and functional characterization of these yield new knowledge about pathogenetic mechanisms and signaling pathways of importance for tumorigenesis and form the basis for development of new targeted cancer therapies.

Our discovery that the MYB-NFIB fusion oncogene in adenoid cystic carcinoma is regulated by IGF1R via the AKT signaling pathway, and that IGF1R inhibitors in combination with other kinase inhibitors can inhibit tumor growth in vitro and in vivo, is the most recent example of this successful approach. Our novel finding that MYB is an oncogenic driver also in patients with the hereditary Brooke-Spiegler tumor syndrome opens new opportunities to, for the first time, test drug-based treatments on patients with this severe disease.

Our group is also involved in a collaborative project together with researchers at the departments of plastic surgery and clinical genetics where we genetically characterize children with craniofacial malformations.

Research tools and resources

We use state-of-the-art genomics approaches and molecular and cellular biology techniques to identify and functionally characterize genomic changes in human glandular tumors to identify new biomarkers and treatment strategies.
