Blood cancers called myeloproliferative neoplasms occur when one of the blood stem cells picks up a mutation. Some patients stay in the chronic phase of the disease for years whereas others rapidly progress with poor outcome. We recently measured when the cancer mutation first occurs and the rate of expansion of the cancer cells in individual patients. We will develop a method that uses the history of disease in each patient to identify those that are at risk of progression.

We recently identified a pervasive, pathogenically relevant mutational mechanism that targets super-enhancers (SE) in DLBCL, leading to target gene deregulation. Here we will dissect the mechanistic role of 3 highly recurrent hotspots in the BCL6, BTG2 and CXCR4 SEs in driving lymphomagenesis and tumor dependency in vitro and in vivo using novel mouse models. These studies will significantly transform our understanding of DLBCL and identify novel therapeutic targets.

Survival rates for those afflicted with MDS have not improved despite extensive effort to identify the key genetic events in its pathogenesis. This project elucidates the contributions of aberrant NPM1 to hematological disorders, with a focus on mitochondrial fitness and inflammasome activation. The resulting insights into the metabolic, genetic and proteomic requirements of homeostasis that are critical to preventing aging will have a major impact on the treatment of hematological malignancies.

Myelodysplastic neoplasms are malignant disorders driven by expansion of diseased hematopoietic stem cells and progression to leukemia. Our investigations have identified the important role of the transporter of amino acid glutamine SLC38A1 in sustaining metabolic demands of rapidly growing malignant stem cells. The goal of this project is to genetically target this transporter to understand its role on tumorigenesis and progression; and to develop SLC38A1 inhibitors as novel therapeutic tools.

Despite remarkable progress in the last 20 years, multiple myeloma remains an incurable disease. In recent years, 2 CAR T cell products that target BCMA on the myeloma cell have been approved. These products result in remarkable initial responses however the duration of these responses has been disappointing. In this proposal, we will take a novel approach to isolate and characterize myeloma cells that interact with CAR T cells but are not killed by them as a potential resistance mechanism.

The goal of our laboratory is to discover, study, and the translate new leukemia therapies to the clinic. In this project, we are studying a signaling pathway, called PI3 kinase gamma, that we believe is important in patients with AML and might lead to new treatments using drugs that target its activity.

CAR-T cells are made from a patient’s own immune cells, altered so that they specifically recognize and kill the patient’s cancer cells. They are effective in many but not all cases of B-acute lymphoblastic leukemia (B-ALL) and diffuse large B-cell lymphoma (DLBCL), among other blood cancers. In this proposal we seek to better understand ways to select T cells that will make better CAR-T cells as well as to treat CAR T cells them in ways to make them work better in the cancer patient.

Peripheral T-cell lymphomas are highly aggressive blood cancer that have very poor survival rate, highlighting the need for new therapies to improve patient survival. We aim to improve our understanding of the characteristics of the individual cancer cells and their interaction with surrounding cells in the tumor environment with the goal of identifying new drugs that we can validate in preclinical models and move into more efficient treatments for lymphoma patients.

Our goal is to perform high-resolution molecular characterization of human leukemia stem cells (LSCs). We have developed an integrated set of single-cell techniques that will assess transcriptional, genomic, and phenotypic features of primary LSC populations obtained from patients undergoing varying forms of treatment. We expect to create a molecular atlas of primary LSCs that will provide the leukemia research community with a powerful resource for the development of improved therapies.

Genetic changes of ASXL1 are very frequent in human blood cancers. We found that the altered forms of ASXL1 protein promote blood cancers through forming tiny liquid-like droplets in the cell. In this project, we aim to develop a method to specifically break these droplets to inhibit its activity in driving blood cancers.

Multiple myeloma is characterized by severe changes in chromosomes that result in gains or losses of genetic material. Several key events disrupt the genome of myeloma cells and are important in defining poor patient outcome, but the biological mechanisms of how they cause high-risk disease is not known. We will perform comprehensive genomic studies, involving six different cutting-edge techniques, to examine the interactions of these high-risk events and identify the mechanisms leading to them.

Project Term: October 1, 2024 - September 30, 2027

This project is the first to explore the origin of a newly discovered type of lymphoma called “BN2-DLBCL”. Mutations in a gene called “SPEN” are a defining feature of these tumors. Strikingly, SPEN mutations are more common in females and cause more deadly disease. Our proposal will reveal for the first time how these tumors originate from the immune system, how they are intimately linked to autoimmune disorders such as Lupus, why they occur preferentially in women, and how to cure them.
