Induction of apoptosis in imatinib sensitive and resistant chronic myeloid leukemia cells by efficient disruption of bcr-abl oncogene with zinc finger nucleases

Journal of Experimental & Clinical Cancer Research, 2018
Background The bcr-abl fusion gene is the pathological origin of chronic myeloid leukemia (CML) and plays a critical role in the resistance of imatinib. Thus, bcr-abl disruption-based novel therapeutic strategy may warrant exploration.

Heat Shock Protein 90: From Molecular Chaperone Function to Therapeutic Targeting in Malignancies

Advanced Science, EarlyView.
In this review, an integrated conceptual framework linking HSP90's molecular chaperone functions to its pathological roles in cancer is proposed. HSP90 serves as a central node that integrates oncogenic signaling, buffers proteotoxic stress, maintains cancer stem cell plasticity, and shapes tumor‐immune interactions, all of which converge to drive ...

Regulation of hTERT by BCR-ABL at multiple levels in K562 cells

BMC Cancer, 2011
Background The cytogenetic characteristic of Chronic Myeloid Leukemia (CML) is the formation of the Philadelphia chromosome gene product, BCR-ABL. Given that BCR-ABL is the specific target of Gleevec in CML treatment, we investigated the regulation of ...

Pharmacokinetic profiling of imatinib in relation to CYP3A4 activity in leukaemia patients

British Journal of Clinical Pharmacology, EarlyView.
Aim Imatinib pharmacokinetics exhibit large interindividual variability because of differences in CYP3A4 activity—the main imatinib‐metabolizing enzyme. While therapeutic drug monitoring is effective, it requires steady‐state conditions and frequent sampling.

Imatinib and leptomycin B are effective in overcoming imatinib-resistance due to Bcr-Abl amplification and clonal evolution but not due to Bcr-Abl kinase domain mutation

Haematologica, 2008
Treatment with imatinib is very effective in Bcr-Abl positive leukemia. However, development of resistance to this drug is a common phenomenon in late stage disease.

Stafib‐2‐CR: an Improved Nanomolar and Selective Inhibitor of the Transcription Factor STAT5b Developed by Conformational Restriction of Stafib‐2

Chemistry – A European Journal, EarlyView.
Conformational restriction strategies to increase the activity and selectivity of the STAT5b inhibitor Stafib‐2 are presented. The best conformationally restricted inhibitor Stafib‐2‐CR has threefold higher activity against STAT5b than Stafib‐2. A cell‐permeable prodrug of Stafib‐2‐CR inhibits phosphorylation of STAT5b in cultured human leukemia cells ...

Evaluation of Morpholino Antisense Oligos’ Role on BCR-ABL Gene Silencing in the K562 Cell Line [PDF]

Cell Journal, 2010
Objective: Chronic myeloid leukemia (CML) develops when a hematopoietic stem cellacquires the BCR/ABL fusion gene. This causes these transformed hematopoietic cellsto have a greater than normal proliferation rate.

Sphingomyelin synthase 1 activity is regulated by the BCR-ABL oncogene[S]

Journal of Lipid Research, 2013
Sphingomyelin synthase (SMS) produces sphingomyelin while consuming ceramide (a negative regulator of cell proliferation) and forming diacylglycerol (DAG) (a mitogenic factor). Therefore, enhanced SMS activity could favor cell proliferation.

Cardiovascular toxicity induced by TKIs in patients with chronic myeloid leukaemia: Are women and men different?

ESC Heart Failure, Volume 12, Issue 2, Page 1447-1454, April 2025.
This study analyzes 148 patients (66 women and 82 men) with chronic myeloid leukemia treated with tyrosine kinase inhibitors, focusing on cardiovascular adverse events. The risk assessment, performed using the HFA/ICOS score, reveals sex‐specific differences: venous thrombosis is more common in women, while arterial thrombosis predominates in men.

Post‐Translational Modifications of Key Proteins in Hematologic Malignancies: Carcinogenic Mechanisms, Biomarker Potential, and New Therapeutic Strategies

iLABMED, EarlyView.
This article reviews the pivotal role of post‐translational modifications of proteins in the development and progression of hematologic malignancies, and explores their clinical translation potential as novel biomarkers and therapeutic targets. ABSTRACT Post‐translational modifications (PTMs) of proteins have emerged as critical regulators in the ...
