Research We Fund

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive blood cancer without adequate treatment. In a genome-wide CRISPR interference screen, BPDCN was highly dependent on the PI3Kγ pathway and specifically the PIK3R5 adaptor subunit. A subset of leukemias may share this vulnerability. We will interrogate the mechanism of this unique dependency and integrate PIK3R5/PI3Kγ targeting with leukemia therapy. Our goal is to provide novel treatments for PIK3R5-dependent malignancies.

My research focuses on myeloproliferative neoplasms (MPN) and the mutations that drive the progression of these blood cancers. Currently, I am investigating mutations in the gene ASXL1, which are associated with a poor prognosis. I am using mouse models and patient-derived cells to determine how ASXL1 mutations mediate epigenetic changes in MPN. My goal is to identify ways of targeting the pathological mechanisms caused by ASXL1 mutation, resulting in new treatment strategies for patients.

We will study the function of ROR1 and ROR2 on HCL cells that we have collected from 120 patients, examining whether they influence expression of genes that can promote the growth/survival of HCL cells. We have made antibodies that are highly specific for ROR1 or ROR2 that react with HCL cells, but not normal blood cells or tissues. We will determine if these antibodies can be used as naked antibodies, antibody-drug conjugates, or in chimeric receptors on T cells to specifically kill HCL cells.

T-cell ALL is an aggressive blood cancer with poor overall survival, high relapse rates, and significant treatment-related side effects. Using primary T-ALL patient samples, this project will study the importance of JAK/STAT signaling and the gene BIRC5 in the pathology of T-ALL driven by DNMT3A mutations using genetic and pharmacological tools. The goal of this proposal is to develop precision medicine approaches for DNMT3A-mutant adult T-ALL patients, a group with poor clinical outcomes
