Research Summary

The Solomon laboratory studies the molecular mechanisms governing human cancer development and progression. We recently discovered frequent inactivating mutations of the cohesin complex gene STAG2 in a spectrum of cancers including glioblastoma, urothelial carcinoma, Ewing sarcoma, and acute myeloid leukemia, which define molecular subgroups of these tumors with distinct clinical outcomes. The cohesin complex is responsible for sister chromatid cohesion following DNA replication and helps ensure faithful chromosome segregation during mitosis, but has also been implicated in additional cellular processes such as regulation of chromatin architecture and gene transcription. We are currently working to determine the function of cohesin during tumorigenesis and to identify therapeutic vulnerabilities in the many cancers harboring cohesin gene alterations. Other ongoing research is focused on identifying the recurrent genetic alterations that drive the many different brain tumor variants including glioblastoma, astrocytoma, oligodendroglioma, ependymoma, other gliomas, medulloblastoma, neurocytoma, meningioma, choroid plexus tumors, and pineal parenchymal tumors.

My clinical interests focus on diagnostic neuropathology, particularly tumors of the central nervous system. Accurate pathologic classification of brain tumors is increasingly dependent on integration of histologic features together with specific genetic alterations that molecularly define the many CNS tumor subtypes. I have thus been working with the Clinical Cancer Genomics Laboratory to advance molecular diagnostic testing for brain tumors at UCSF, where I function as the Director of Molecular Neuro-Oncology responsible for supervising and interpreting all genomic testing performed on CNS tumors at UCSF Medical Center.
