A major cause of relapse after therapy is the persistence of measurable residual disease (MRD) cells—cancer cells that remain after treatment and eventually spread. Due to technical and logistical challenges in accessing and analyzing MRD cells, the molecular and cellular pathways that enable MRD progression remain poorly understood. Dr. Bachireddy will use innovative molecular tools to analyze tissue samples from blood cancer patients at a single-cell level to unlock insights into MRD progression. Using cutting-edge machine learning approaches, he will identify immunosuppressive mechanisms that may be targeted to halt MRD progression. Beyond these blood cancers, he aims to reveal organizing principles of MRD progression that are relevant across human cancers.

One of the persistent challenges in treating high-risk pediatric leukemia, particularly in cases of acute megakaryoblastic leukemia (AMKL), is the high incidence of relapse due to resistance to standard treatments such as chemotherapy and bone marrow transplantation. T cell therapy has shown potential in treating various types of leukemia, offering the prospect of overcoming mechanisms that tumor cells employ to evade traditional therapies. However, a significant challenge in T cell therapy for AMKL lies in identifying T cells that are able to recognize and target leukemia cells specifically. Dr. Balood’s research is dedicated to advancing T cell therapy for AMKL. He plans to test and identify T cell clones that specifically recognize and eliminate leukemia cells with the goal of translating these findings into an effective T cell therapy with minimal toxicity in leukemia patients. Dr. Balood received his PhD from University of Montreal School of Medicine, Montreal, his MS from Tarbiat Modares University School of Medicine, Tehran, and his BS from Shahid Chamran University of Ahvaz, Ahvaz.

Dr. Bhansali is studying how epigenetic processes—specifically the three-dimensional folding of DNA—promote the development, growth, and survival of cancers. His research focuses on T-cell acute lymphoblastic leukemia (T-ALL), an aggressive blood cancer affecting both children and adults for which traditional chemotherapy remains the mainstay of treatment. LDB1 is a protein involved in the process of DNA folding that partners with another protein called LMO2, which is highly expressed in up to 75% of T-ALL. Dr. Bhansali hypothesizes that LDB1/LMO2 rewire the normal gene expression machinery in our blood cells in a way that activates cancer-promoting genes to cause leukemia. Targeting this process may shed light on new treatment avenues and ways to overcome resistance to treatment.

Myeloid neoplasms (MN), including acute myeloid leukemia and myelodysplastic syndrome, are lethal blood cancers. The genetic mutations in the blood that lead to MN can occur years before diagnosis and maintain almost normal function before transformation. Certain mutations, including those in the gene IDH2, have been identified as high-risk for developing MN. Individuals with a reduction in the number of mature blood cells (cytopenias) who harbor acquired mutations in their blood, yet do not meet criteria for a cancer diagnosis, have a condition called cytopenias of undetermined significance (CCUS). These individuals almost invariably develop MN. Dr. Bolton will conduct a clinical trial to evaluate whether the IDH2 inhibitor enasidenib can be used as a therapy for CCUS. She will assess mechanisms of resistance and determine whether enasidenib can prevent the development of MN. This represents the first use of genetically targeted therapy for cancer prevention.

Acute myeloid leukemia (AML) with rearrangements of the KMT2A gene (KMT2A-r) or NPM1 mutation (NPM1m) affect children and adults and can be difficult to treat even with highly intensive therapy. Targeted, less toxic therapies are urgently needed. Menin inhibitors are novel small molecules that block a critical interaction between the KMT2A protein and another protein called menin. This protein-protein interaction is essential in sustaining both KMT2A-r and NPM1m AML. Menin inhibitors have now entered clinical trials for children and adults have shown promising results. However, it has also been demonstrated that up to 40% of patients will develop resistance to a menin inhibitor when it is given alone due to a mutation in the MEN1 gene, which encodes the protein menin. Dr. Bourgeois is investigating whether combination therapy can prevent or overcome MEN1 mutations that confer resistance to menin inhibitors. Additionally, he is developing models to understand how and why resistance to menin inhibitors is sometimes driven by MEN1 mutations, but other times not. The overarching goal of the project is to identify combination therapies that prevent and overcome menin inhibitor resistance and to better understand the different ways in which resistance to menin inhibitors develops.

Myelodysplasia and acute myeloid leukemia are blood cancers with a poor prognosis. At the root of these malignancies are cells harboring mutant forms of proteins with dysfunctional activity which results in abnormal cell behavior and drives disease progression. The focus of my project is the development of new therapeutics that precisely identify cells with mutant forms of the proteins and, by harnessing their aberrant biological activity, causes those cells to self-destruct. These selective therapeutics will be able to kill cancer cells but leave the healthy cells intact proving more effective and having less side-effects than the chemotherapies currently in use.

About 70% of pediatric leukemias and up to 10% of adult leukemias are caused by a genetic disruption in which the mixed lineage leukemia (MLL) 1 gene breaks off and attaches to a different chromosome. This event, known as a chromosomal translocation, gives rise to a distinct subset of leukemias called MLL-rearranged acute myeloid leukemia (AML). Studies have shown that a protein called KMT2D plays a critical role in the development of MLL-rearranged AML. However, the potential of KMT2D as a novel therapeutic target remains underexplored. Dr. Cruz [The Mark Foundation for Cancer Research Physician-Scientist] will use molecular biology, epigenetic, and biochemistry approaches to describe the precise molecular mechanism by which KMT2D regulates gene expression in MLL-rearranged AML. Her work will provide insight into potentially targetable proteins for this aggressive blood cancer.

Acute myeloid leukemia (AML) is hard to cure compared to other childhood leukemias and lymphomas. Current standard-of-care AML treatment is very toxic; childhood AML survivors often have side effects later in life from their treatment, including heart disease, infertility, and additional cancers. There is a pressing need for new AML treatments that are less toxic and more effective. Dr. Decker’s research is focused on developing novel inhibitors of a protein called N-Ras, one of the most common mutations in pediatric AML. Dr. Decker hopes by disrupting N-Ras function to sensitize AML to existing therapies and improve outcomes for patients. Dr. Decker received his MD and PhD from Columbia University, New York and his BS from Stanford University, Stanford.

About 70% of pediatric leukemias and 10% of adult leukemias are caused by a genetic disruption in which the mixed lineage leukemia (MLL) 1 gene breaks off and attaches to a different chromosome. This event, known as a chromosomal translocation, gives rise to a distinct subset of leukemias called MLL-rearranged acute myeloid and lymphoblastic leukemias (AML or ALL). Novel treatments for these cancers represent a major unmet medical need. However, the development of therapeutics is hampered by a lack of basic understanding of how the MLL translocations disrupt the function of affected cancer cells. Dr. Farnung will use biophysical and structural biology approaches to visualize how MLL translocations function at the atomic level and influence the important process of gene transcription. His work will elucidate the precise molecular mechanisms that drive acute leukemias and provide a platform for the development of novel therapeutic strategies against these cancers.

Many cancer diagnostic and treatment strategies use markers on the cell surface to find and kill cancer cells in a sea of healthy tissue. Dr. Flynn’s [Bakewell Foundation-Rachleff Innovator] research aims to expand our knowledge of what molecules are found on the surface of cancer cells. He will focus on acute myeloid leukemia (AML), as there is a major unmet clinical need for new curative treatments. Specifically, he aims to define RNA as a new cell surface molecule that could have unique structures on AML cells. With this knowledge he will develop antibodies to selectively detect cancer cells and enable tumor killing. Because tumors from other parts the body also express RNA on their surface, this strategy is expected to be broadly applicable to other cancer types.
