Abstract
Chronic Myeloid Leukemia (CML) is characterized by the BCR::ABL1 fusion gene, driving uncontrolled myeloid cell proliferation. Furthermore, metabolic dysregulation contributes to disease progression. Despite the efficacy of tyrosine kinase inhibitors (TKIs), unresolved clinical needs persist, necessitating refined preclinical models. This study compared responses of three commonly used CML cell lines (K562, LAMA84, KCL22) to five TKIs (imatinib, nilotinib, dasatinib, bosutinib, ponatinib) and a Specifically Targeting the ABL Myristoyl Pocket (STAMP) inhibitor commonly used in clinical settings. Using morphological assessments, viability and metabolic activity assays, glutamate intake evaluations, and gene expression analyses we observed distinct responses among cell lines. TKIs and STAMP inhibitor treatments showed varying impacts on morphological features, cell viability, metabolic activity, and gene expression profiles, highlighting significant differences in cellular responses. This emphasizes the necessity of considering cellular heterogeneity in CML research. This comprehensive comparison provides valuable insights for refining preclinical models and enhancing translational relevance in CML research and treatment development. Understanding the diverse responses of CML cell lines to TKIs and STAMP inhibitor facilitates the selection of appropriate models for specific research questions, ultimately improving the accuracy and reliability of preclinical studies in CML.
期刊介绍:
Each month, the journal publishes easy-to-assimilate, up-to-the minute reports of experimental findings by researchers using a wide range of the latest techniques. Promoting the aims of cell biologists worldwide, papers reporting on structure and function - especially where they relate to the physiology of the whole cell - are strongly encouraged. Molecular biology is welcome, as long as articles report findings that are seen in the wider context of cell biology. In covering all areas of the cell, the journal is both appealing and accessible to a broad audience. Authors whose papers do not appeal to cell biologists in general because their topic is too specialized (e.g. infectious microbes, protozoology) are recommended to send them to more relevant journals. Papers reporting whole animal studies or work more suited to a medical journal, e.g. histopathological studies or clinical immunology, are unlikely to be accepted, unless they are fully focused on some important cellular aspect.
These last remarks extend particularly to papers on cancer. Unless firmly based on some deeper cellular or molecular biological principle, papers that are highly specialized in this field, with limited appeal to cell biologists at large, should be directed towards journals devoted to cancer, there being very many from which to choose.
