Suppression of autophagy by BCR ABL

Frontiers in Bioscience, 2012
Imatinib and second generation BCR/ABL tyrosine kinase inhibitors (TKIs) serve now as standard therapies for patients with chronic myelogenous leukemia (CML); however, CML stem cells are intrinsically insensitive to the cell death-inducing effects of TKIs, allowing the persistence of a "reservoir" of BCR/ABL-expressing CML-initiating cells potentially ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Targeting BCR-ABL+ stem/progenitor cells and BCR-ABL-T315I mutant cells by effective inhibition of the BCR-ABL-Tyr177-GRB2 complex

Oncotarget, 2017
Treatment of BCR-ABL+ human leukemia has been significantly improved by ABL tyrosine kinase inhibitors (TKIs), but they are not curative for most patients and relapses are frequently associated with BCR-ABL mutations, warranting new targets for improved treatments.

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 ...

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 ...

Genetic requirement for Ras in the transformation of fibroblasts and hematopoietic cells by the Bcr-Abl oncogene. [PDF]

, 1995
To determine the functional importance of Ras in transformation by Abl oncogenes, we used a genetic approach to measure the effect of impaired Ras activity on the ability of Bcr-Abl or v-Abl to transform cells.

Targeting quiescent leukemic stem cells using second generation autophagy inhibitors [PDF]

, 2019
In chronic myeloid leukemia (CML), tyrosine kinase inhibitor (TKI) treatment induces autophagy that promotes survival and TKI-resistance in leukemic stem cells (LSCs).

Oncogenic fusion protein BCR-FGFR1 requires the breakpoint cluster region-mediated oligomerization and chaperonin Hsp90 for activation. [PDF]

, 2020
Mutation and translocation of fibroblast growth factor receptors often lead to aberrant signaling and cancer. This work focuses on the t(8;22)(p11;q11) chromosomal translocation which creates the breakpoint cluster region (BCR) fibroblast growth factor ...

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.

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.
