Research we fund

My research focuses on why and how risk of acute myeloid leukemia (AML) increases with aging. Studying naturally aged mouse models in combination with mice engineered to express mutations commonly found in human blood stem cells with aging, we are investigating whether certain inflammatory factors that increase during aging increase the risk of leukemia. My goal is to identify biomarkers to assess risk of AML development in aging individuals and define new therapeutic targets to prevent AML.

This proposal aims to understand the molecular mechanisms underlying response to AZA therapy in MDS, as a basis for developing more effective therapies. A ribonucleotide, AZA’s effects on RNA remain unknown. Here, we will investigate the impact of in vivo AZA therapy on RNA alternative splicing and DNA demethylation in MDS patients. Secondly, we will investigate whether AZA treatment exposes neoepitopes in the dysplastic cells of patients, which could be exploited for cancer immunotherapy in MDS

The most common cause of MDS is a genetic mutation occurring in blood cells that affects a process called “RNA splicing”. The most commonly mutated RNA splicing factor gene is called SF3B1. We now know that many patients with MDS carry mutations in SF3B1 but we do not know why these mutations cause disease. Dr. Bradley proposes to determine how mutations in SF3B1 cause MDS and potentially create new opportunities for treating this disease.

There are widely recognized but unexplained sex differences in cancer incidence and outcomes, including in blastic plasmacytoid dendritic cell neoplasm (BPDCN), an aggressive leukemia that occurs over 3 times more frequently in men. We aim to identify male-female differences in plasmacytoid dendritic cells, the blood cell involved in BPDCN, to better understand this disease. Our goal is to use what we learn to improve the treatment of BPDCN and related blood cancers for both men and women.

The oncoprotein eIF4E is dysregulated in many cancers including AML. We show that eIF4E drives production of the glycosaminoglycan hyaluronan (HA). Further, HA elevation alters the surface architecture of high-eIF4E AML cells and this is required for eIF4E’s oncogenic activity. We will explore HA’s involvement in AML and the efficacy of depleting HA in patients using hyaluronidase in a Phase I trial in AML.

Adoptive T cell therapies for acute myeloid leukemia face numerous hurdles such as limited target antigens, immunosuppressive tumor environment as well as the loss of efficacy due to downregulation of the targeted antigen. The goal of our project is to address some of these challenges with a single T cell product targeting multiple tumor associated antigens that have limited expression on healthy tissues via a novel combination of native T cell receptor and gene engineered CAR targeting.

Drug resistance in AML can develop via a non-genetic process which remains poorly understood. Using our novel cellular barcoding technology that can trace the growth of thousands of cancer cells, our research will identify genes that are switched on or off in AML cells that lead to drug resistance and relapse. This work will reveal the factors underpinning non-genetic drug resistance that may be targeted with new drugs to prevent relapse and ultimately improve quality of life and survival.

Here we propose to study blood DNA from 1500 people who have had extensive genetic and aging-related tests over many years as participants of the "Immunoageing" study (http://www.immunoageing.eu/index.html). We propose to study these people for the presence of age-related clonal hematopoiesis (ARCH) to understand what factors are associated with ARCH and its expansion. Our aim is to use these findings to help prevent ARCH from progressing to myeloid cancer in at risk individuals identified by future screening programs, which we and others developing separately.

Blocking the progression of smoldering multiple myeloma (SMM) to active MM is an unmet clinical need. In primary mouse models of MM, we aim at demonstrating that modulation of the gut microbiota by vaccination against the commensal Prevotella heparinolytica and/or colonization by P. melaninogenica, also in combination with anti-PD-L1 antibodies, inhibit the progression of asymptomatic MM to full-blown disease. Our findings are expected to provide the ground for clinical trials in SMM patients.

Follicular lymphomas (FL) depend on stromal cells for survival and proliferation and evade T-cell immune surveillance. Although indolent, most FLs eventually undergo either progression or transformation to an aggressive lymphoma. Effective treatments to prevent this remain a critical unmet need. This proposal will develop novel, mechanism-based therapeutic regimens for FL that overcome defective immune surveillance, prevent FLs from receiving stromal support and prevent disease progression.

Most T cell acute lymphoblastic leukemia (T-ALL) patients respond to chemotherapy, however many relapse with limited therapy options. To address this problem, we are utilizing a newly-developed human T-ALL system to study two potential therapy targets (NOTCH1 and MLL1) and their interaction, to determine if they can be co-inhibited to eradicate disease. Since compounds that inhibit NOTCH1 and MLL1 are already in development, this novel combination strategy could lead to clinical approval sooner.
