MATLAWSKA LAB
Breaking Barriers in Leukemia: From Bone to Brain
Every Step Matters
OUR MISSION
At the Matlawska Lab, we are driven by curiosity and committed to impact. Our research focuses on understanding the mechanisms that drive high-risk leukemia, with an emphasis on T-cell acute lymphoblastic leukemia (T-ALL), its progression, treatment resistance, and infiltration into sanctuary sites such as the central nervous system (CNS).
By integrating cancer biology, immunology, and systems-level approaches—including transcriptomics, metabolomics, and in vivo modeling—we investigate how leukemia cells hijack inflammatory signaling, metabolic pathways, and the microenvironment to survive and spread. We aim to uncover the cellular and molecular cues that govern leukemic cell behavior, with the goal of identifying new biomarkers and developing more effective, targeted therapies for children and adults with leukemia.
Our lab is part of the Department of Cell, Developmental and Integrative Biology (CDIB) at the University of Alabama at Birmingham and is affiliated with the O’Neal Comprehensive Cancer Center. We are a collaborative, multidisciplinary team that values scientific rigor, creativity, mentorship, and translational discovery.
PROJECT OVERVIEW
The Matlawska Lab investigates the biology and pathogenesis of T-cell acute lymphoblastic leukemia (T-ALL), an aggressive hematologic malignancy characterized by rapid proliferation, widespread dissemination, and poor outcomes in high-risk cases. Extensive evidence indicates that central nervous system (CNS) infiltration is a devastating complication of T-ALL that drives relapse and therapy failure. Our research explores the mechanisms by which leukemic cells breach CNS barriers, adapt to the unique meningeal microenvironment, and exploit inflammatory and other signaling pathways to survive and evade treatment. By dissecting these processes at the cellular and molecular levels, we aim to identify actionable vulnerabilities and develop targeted strategies to prevent relapse and treat CNS leukemia.
Our lab integrates a broad range of advanced research tools and methodologies to study T-ALL progression and CNS infiltration. We utilize a variety of in vivo mouse models and primary patient samples, alongside 2D and 3D co-culture systems that mimic the CNS microenvironment. Our toolkit also includes state-of-the-art imaging, multiparameter flow cytometry, single-cell RNA sequencing, multi-omics profiling, and CRISPR/Cas9 genome editing. These powerful approaches allow us to dissect key signaling nodes and networks, probe metabolic adaptations, and evaluate novel drug combinations with precision. Our overarching goal is to identify the molecular drivers of T-ALL progression and CNS infiltration and to uncover new therapeutic vulnerabilities that can improve long-term outcomes for patients.

CNS Infiltration and Microenvironmental Adaptation
Multiple projects in the lab investigate how T-ALL cells breach the blood–CSF and blood–brain barriers and establish residence in the CNS. We focus on the role of inflammatory cues (e.g. CXCL10) produced by meningeal stromal cells, integrin-mediated adhesion, and the unique metabolic adaptations that allow leukemic cells to thrive in the CNS niche. By combining mouse models of CNS leukemia with functional assays and omics analyses, we aim to identify targetable pathways to prevent CNS infiltration and relapse.
RUNX2 and Metabolic Reprogramming in T-ALL
We explore how the transcription factor RUNX2 drives metabolic rewiring in aggressive T-ALL. Our data show that RUNX2 enhances glycolytic and glutamine metabolism and supports chemoresistance and extramedullary dissemination. Using Runx2 knockout mice, CRISPR/Cas9 knockout cell lines, and stable-isotope tracing, we dissect RUNX2’s downstream transcriptional targets and identify metabolic vulnerabilities that can be exploited therapeutically.
Targeting BCL-2 and Proteasome Stress
This project evaluates the therapeutic synergy between venetoclax (BCL-2 inhibitor) and proteasome inhibitors in high-risk T-ALL. We use in vitro assays, xenograft models, and flow cytometry to assess how disrupting apoptotic pathways and protein homeostasis induces selective cytotoxicity in leukemic cells, particularly those resistant to standard chemotherapies. Our goal is to define optimal dosing and identify predictive biomarkers of response.
Retinoids and Rexinoids as Differentiating Agents
This translational project explores the anti-leukemic potential of nuclear receptor ligands, including all-trans retinoic acid and selective RXR agonists, to promote differentiation and impair the proliferation of T-ALL. Using transcriptional and protein-level analyses, we test these agents alone and in combination with standard therapies to identify promising approaches for reducing tumor burden and preventing T-ALL relapse.
