Research we fund

Few treatment options are available for T cell leukemias and lymphomas, collectively called T cell cancers that affect ~100,000 patients worldwide each year. The current proposal will generate new antibodies attached to drugs and toxins that kill the T cell cancers. Importantly, the antibodies will preserve enough healthy T cells to maintain a functioning immune system. These modified antibodies may improve patient outcome and limit side effects associated with traditional chemotherapies.

The mitogen-activated protein kinase (MAPK) pathway is activated in high-risk leukemia and is a hallmark of resistance to therapies. This project uses patient-derived xenograft models of relapsed pediatric ALL and AML with activated RAS/MAPK to test whether clinically relevant MAPK mutations activate the VAV3/RAC pathway and if pharmacological inhibition of that pathway by a small molecule we developed synergizes with a MAPK-inhibitor to provide a new treatment strategy for RAS-driven leukemia.

SIRPα+ macrophages mediate resistance to lenalidomide in B-cell lymphoma, limiting the activity of immunotherapy for these patients. Therefore, we propose a phase I/II study, investigating the safety and efficacy of ALX148, a novel fusion protein of the SIRPα binding domain, in combination with rituximab and lenalidomide in patients with B-cell lymphoma. We hypothesize that this combination will be safe and effective, providing a chemotherapy-free option for these patients.

Leukemia often results from aberrant gene expression caused by epigenetic alterations. Previously we discovered a novel histone acetylation reader domain in the ENL protein and demonstrated that this domain is essential for the survival of a wide range of acute leukemias, making it an attractive therapeutic target. We will develop specific inhibitors of ENL activity in acute leukemias and will use mouse models to define the role of ENL mutations identified in patients in leukemogenesis.

Our research program aims to gain a deeper understanding of the pathobiology of T-ALL and HSTL.

To this end, we will use novel mouse models, cutting-edge techniques and comprehensive genetic, pharmacological and metabolic interventions. In addition, we will perform unbiased experiments to identify novel therapeutic targets.

Our goal is to uncover new tools and targets for the treatment of T-ALL and HSTL, which could be used for the benefit of patients in the short/mid-term.

The long-term goal of my research program is to improve the outcomes for patients with high-risk myeloid blood cancers, particularly those with loss of chromosome 7 or CUX1. We are tackling this question using an arsenal of innovative methods and tools, including mouse models, human cells and patient samples, and state-of-the-art technologies to examine the cancer cell genome. Accomplishing this work will reveal new treatments and strategies for preventing blood cancers from arising.

My lab is focused on the immune regulatory mechanisms and ubiquitin-dependent machinery in lymphoma. We have established multiple high-throughput screening technologies and animal models to rapidly and accurately identify critical pathways that are suitable for targeted therapy and immunotherapy. Gaining insight into the pathological roles of these pathways can lead to improved understandings of the molecular circuitry that drives lymphoma pathogenesis and provide novel therapeutic strategies.

Our research program is focused on understanding the intersection between signaling and transcriptional dysfunction in myeloid leukemias. We leverage murine models, cell lines and human samples to uncover how biological context shapes the manifestation of oncogenic programs at the molecular level. Our long-term goal is to harness this knowledge to identify multipronged therapeutic strategies that improve outcomes for patients with myeloid malignancies.

Our central goal is to improve clinical outcomes in patients with myeloid malignancies through developing an enhanced mechanistic understanding of disease. We use multiomic analyses of primary patient samples combined with complementary laboratory models using mice and cell lines to generate and test our hypotheses. The results of our studies will help improve patient outcomes by identifying strategies to mitigate risk of disease progression/relapse and treatment toxicity.

The goal of this proposal is to investigate the significance of genes of the ubiquitin proteasome system (UPS) that are mutated in Diffuse Large B-cell Lymphoma (DLBCL). Our studies leverage the expertise in the molecular modeling of the UPS in the pathogenesis of DLBCL utilizing mouse models, patient derived xenotransplant (PDX) and cell lines. Our goal is the understanding of how genetic mutations contribute to disease development, progression and therapeutic outcome.
