Pediatric Malignancies

Our laboratory investigates the molecular underpinnings of pediatric malignancies with a focus on acute myeloid leukemia (AML) and Ewing sarcoma. Through advanced single-cell genomics and functional studies, we aim to identify novel therapeutic targets and understand disease mechanisms to improve outcomes for children with cancer.

Ewing Sarcoma

Understanding Tumor Heterogeneity and the Microenvironment

Multimodal Single-Cell Analysis of Fusion-Regulated Programs

Using cutting-edge multimodal single-cell approaches, we characterized distinct transcriptional programs regulated by EWS::FLI1 fusions in Ewing sarcoma, revealing critical insights into tumor cell plasticity and therapeutic vulnerabilities.

Tumor Microenvironment Remodeling

With our collaborators, we identified cancer-associated fibroblast-like tumor cells that actively remodel the Ewing sarcoma tumor microenvironment, providing new understanding of how these tumors interact with their surroundings.

EWS::FLI1 and Tumor Cell Plasticity

This work demonstrated how EWS::FLI1 and HOXD13 cooperatively control tumor cell plasticity in Ewing sarcoma, identifying key regulatory networks that maintain the malignant phenotype.

Pediatric Acute Myeloid Leukemia

Molecular Characterization and Therapeutic Targeting

CAR T Cell Therapy for CBFA2T3-GLIS2 AMKL

With our collaborators, we developed a preclinical model of CBFA2T3-GLIS2 acute megakaryoblastic leukemia and identified FOLR1 as a promising CAR T cell target, opening new therapeutic avenues for this aggressive pediatric malignancy.

NUP98 Fusions in Pediatric AML

With our collaborators, we outline a comprehensive molecular characterization of NUP98 fusions revealed distinct clinical and biological features, improving risk stratification for children with this AML subtype.

Cryptic ALK Fusions in Monosomy 7 AML

With our collaborators, we identified and characterized cryptic ALK fusions in monosomy 7 AML, demonstrating their functional consequences and establishing them as targetable vulnerabilities with available ALK inhibitors.

Manselle MK et al. (2023) Pediatr Blood Cancer 70(4): e30180 PMID: 36720638

Integrated Stem Cell Signatures for Risk Stratification

Our collaborators show an integrated analysis of stem cell signatures and cytomolecular features provides improved risk determination in pediatric AML, helping to personalize treatment strategies.

CBFB-MYH11 Fusion Transcript Analysis

Our collaborators demonstrate that CBFB-MYH11 fusion transcripts distinguish AML cases with distinct molecular landscapes and clinical outcomes, refining prognostic capabilities.

Huang BJ et al. (2021) Blood Adv 5(23): 4963-4968 PMID: 34547772
