Research Summary

Our laboratory is focused on the biology of brain tumors, in particular diffuse gliomas in adults and children. We study primary human samples at single-cell resolution using transcriptomic and genomic approaches. We reconstruct the cellular composition of patient tumors and relate it to genetic mutations. We model how brain cancer cells exploit developmental programs to establish distinct cellular states. Additionally, the laboratory investigates how genetic events affecting genes involved in chromatin regulation rewire cancer cells’ identities to contribute
to cellular transformation. We seek to identify common programs that would offer novel therapeutic options in these dismal diseases.

 

Heterogeneity in brain tumors assessed at single-cell level

We are deploying cutting-edge single-cell genomic, epigenomic and transcriptional profiling to clinical samples. Our unique approach allows us for the first time to relate genotype to phenotype at single-cell resolution in clinical tumor specimens. Through our efforts, we are redefining our understanding of malignant cell subpopulations in glioblastoma, oligodendroglioma, astrocytoma, diffuse intrinsic pontine glioma, medulloblastoma and synovial sarcoma. In addition, our single-cell genomics efforts are providing invaluable insights into myeloid cells and T cell programs in clinical tumors.

Targeting Cellular States in Glioblastoma

Although cancer is a genetic disease, malignancies are associated with aberrations in gene expression related to both cancer cell-intrinsic and -extrinsic factors. Genetic, epigenetic and microenvironmental cues are integrated at the cellular level into states of expression that govern many critical facets of tumor biology, such as tumor growth, metastasis, and resistance to treatment. A better understanding of the precise determinants of the cellular states that drive cancer is a critical goal with broad implications for oncology. Our lab is pursuing the goal of targeting the four cellular states of glioblastoma that our single-cell RNA-sequencing efforts have uncovered. To this end, we established faithful models of cellular states observed in patients, dissect the rules governing cellular transitions using single-cell barcodes and leverage genome editing and small molecules targeting defined pathways to identify specific vulnerabilities for glioblastoma.
