The NALM6 cell line, established in 1979 from the bone marrow of a pediatric patient with acute lymphoblastic leukemia (ALL), serves as a crucial tool in leukemia research. Its origin in B-cell precursor ALL renders it valuable for studying B-lineage leukemogenesis and therapeutic interventions. Over decades, NALM6 has been extensively utilized to investigate molecular mechanisms underlying leukemic progression, drug sensitivity, and resistance. Additionally, the integration of luciferase and GFP reporter genes into NALM6 cells facilitates real-time monitoring of cellular events such as proliferation, apoptosis, and response to therapeutic agents. This modification enhances the utility of NALM6 in high-throughput drug screening assays and in vivo imaging studies. Thus, the NALM6-Luc/GFP reporter cell line amalgamates the robustness of NALM6 with the versatility of luciferase/GFP technology, offering a powerful platform for elucidating leukemia pathogenesis and evaluating novel therapeutic strategies.
Despite CAR T-cell therapy's success against hematologic malignancies, resistance and recurrence persist, with unclear underlying markers or mechanisms. Researchers conducted an unbiased genome-wide CRISPR/Cas9 screening to investigate mechanisms of resistance to CAR T-cell therapy in hematologic malignancies. They identified loss of NOXA, a BCL2 family protein, as a critical regulator of resistance. Low NOXA expression correlated with worse survival in clinical trials. Pharmacological enhancement of NOXA sensitized cancer cells to CAR T-cell therapy both in vitro and in vivo. This study highlights NOXA as a potential predictive marker for CAR T-cell therapy response and survival, suggesting pharmacological targeting of NOXA as a promising strategy to enhance CAR T-cell therapy efficacy.
