A recent report from the Autonomous University Barcelona discusses new research on BCR-ABL tyrosine kinase inhibitors. The study focuses on the quantification of histone H1 subtypes using targeted proteomics. Histone H1 is involved in the regulation of chromatin structure, and alterations in the protein levels of different H1 subtypes have been observed in cancer. The researchers developed a mass spectrometry-based assay for the quantification of H1 subtypes and found differences in the H1 complement in chronic myeloid leukemia patients between responders and non-responders to imatinib therapy. Further research is needed to determine if the H1 content or subtype composition could help predict imatinib response. [Extracted from the article]

A study conducted by researchers at Qingdao University in Shandong, China, explores the role of circular RNA 0080145 (circ_0080145) in the resistance of chronic myeloid leukemia (CML) to imatinib (IM) therapy. The study found that circ_0080145 is upregulated in IM-resistant CML patients and cells. Silencing circ_0080145 suppressed IM resistance, cell growth, and glycolysis, and induced apoptosis in IM-resistant CML cells. The study suggests that circ_0080145 contributes to IM resistance by modulating the miR-326/PPFIA1 axis, providing a potential avenue for CML therapy. [Extracted from the article]

A recent study conducted at the All India Institute of Medical Sciences (AIIMS) compared the efficacy of hydroxyurea (HU) combined with imatinib versus imatinib monotherapy in newly diagnosed chronic phase chronic myeloid leukemia (CML-CP) patients.

A recent study conducted in Chandigarh, India, examined the effects of imatinib mesylate (IM) on the reproductive system of female patients with chronic myeloid leukemia (CML). The study found no significant differences in ovarian reserve parameters, such as menstrual cycle characteristics, anti-Mullerian hormone (AMH) levels, and antral follicle count (AFC), between CML patients receiving IM therapy and newly diagnosed patients who had not yet started treatment. However, the study did find that patients taking IM for at least one year had a significantly lower age at menopause compared to the control group, indicating a potential risk of early iatrogenic menopause. Further investigation through larger studies is needed to confirm these findings. [Extracted from the article]

A study conducted at Nehru Hospital in Chandigarh, India, explored the impact of T-regulatory cells (Tregs) and PD-1 + CD8 T-cells in patients with chronic myeloid leukemia (CML) who were treated with imatinib mesylate.

The researchers suggest that these findings indicate the potential for immunotherapy as a promising approach to managing immune exhaustion in CML patients. The study has been peer-reviewed and published in the Indian Journal of Hematology and Blood Transfusion. [Extracted from the article]

A study conducted by researchers at the General Hospital of Ningxia Medical University has investigated the role of SPRY4 intronic transcript 1 (SPRY4-IT1) in gastrointestinal stromal tumors (GIST).

A new report from researchers at St. Louis University discusses the clinicopathologic features of a case of pityriasis rosea-like drug eruption secondary to imatinib, a drug used in the treatment of chronic myeloid leukemia. Pityriasis rosea is a skin condition characterized by erythematous and scaly lesions, and drug eruptions that resemble this condition have been reported. The distinction between classic pityriasis rosea and drug-related eruptions is important for management purposes. The study found that while the clinical morphology of the drug-related eruption mimics classic pityriasis rosea, unique histopathologic findings can aid in distinguishing between the two.

A recent study conducted at the Medical University of Gdansk in Poland explored the potential neuroprotective effects of a non-covalent conjugate of imatinib with TP10 in the context of Parkinson's disease. Imatinib, a tyrosine kinase inhibitor, has shown promise in preclinical animal models of the disease by inhibiting c-Abl, a non-receptor tyrosine kinase associated with oxidative stress. However, the poor distribution of imatinib within the brain tissue prompted researchers to test a conjugate of imatinib with TP10, which has high translocation activity across cell membranes. The experiments conducted on HT-22 neuronal cells indicated that the conjugate reduced oxidative stress, apoptosis, and mortality more effectively than imatinib alone, without activating the ABCB1 protein. These findings suggest that the imatinib+TP10 conjugate may have potential as a neuroprotective treatment for Parkinson's disease and warrant further in vivo research. [Extracted from the article]

A study conducted by researchers at Universite Paris Cite has found that certain genetic variants are associated with the plasma concentration of the drug imatinib in patients with chronic myeloid leukemia (CML).

These SNPs were found in genes encoding proteins involved in cell adhesion, transcription/translation, and the diffusion and transit of imatinib through membranes or epithelial barriers. The study suggests that genetic factors may contribute to the variability in imatinib plasma concentration among CML patients. [Extracted from the article]
