Univariate and multivariate analyses showed heightened ARG1 levels and a transition from PD1/PDL1 dominance at 3 months to TIM3/GAL9 at 12 months in non-optimal responders (BCR::ABL1 ≥ 0.1%). Our longitudinal design offers a deeper exploration of immune gene expression dynamics in CML patients on imatinib, highlighting its potential implications for therapy outcomes.

Samples derived from cases from both the experimental and the control arm, based respectively on ponatinib followed by blinatumomab and on a combination of imatinib and conventional chemotherapy. While some groups reported a higher predictive prognostic power of IG/TR monitoring, our findings do not confirm these data, also in view of the very low rate of relapses so far observed. Nevertheless, a double-hit strategy may be informative for MRD monitoring and possibly for the distinction between typical/lymphoid Ph+ ALL vs multilineage/CML-like Ph+ ALL.

Their conjugation with the drugs Irinotecan, Imatinib, and Methotrexate was also confirmed using UV-Vis, FTIR, and Dynamic light scattering (DLS). The result of the methylthiazol tetrazolium (MTT) assay showed that conjugated AgNPs and AuNPs with Irinotecan had a higher toxic effect on the A549 cancer cell line than AgNPs and AuNPs conjugated with Imatinib. This study provides a promising avenue for further investigation and development of nanoparticle-drug conjugates as a potential cancer immunotherapy strategy.

Thirty-five patients will be recruited with an interim analysis planned after recruitment of 20 patients. The study is open for inclusion and 4 patients have been included as of 10th of June 2024.

In addition to BCR-ABLIS level, HT of BCR-ABLIS can be used as another important predictor of treatment efficacy in CML patients. The combination of BCR-ABLIS level and HT has a more accurate predictive value for long-term molecular response of CML patients after TKI treatment.

He was found to be positive for BCR-ABL by reverse transcription polymerase chain reaction (RT-PCR), thus confirming the diagnosis of CML. He received imatinib 400 mg/day and subsequently experienced resolution of symptoms and complete hematological response by the 12th week of therapy.

For example, imatinib acts by targeting cell surface receptors, and these inhibitors have shown potential for the control and treatment of tumor growth, angiogenesis, and metastasis. Imatinib, for example acts by targeting cell surface receptors, and these inhibitors have shown the future direction toward the control and treatment of tumor growth, angiogenesis, and metastasis.

Management included observation in 6 (46.3%), hydroxyurea in 3 (23.1%), imatinib in 3 (23.1%) and Interferon-α (IFN-α) in 1 (7.7%) patients. Effective management of newly diagnosed CML-CP during pregnancy is contingent on the trimester of presentation. Further research and collaboration are warranted to develop standardised guidelines for managing pregnancy-associated CML, particularly in LMICs.

Our findings reveal a significantly higher proportion of Tregs and PD-1 + CD8 T-cells in patients with CML-CP compared to healthy controls, notably diminished following imatinib treatment. These observations suggest the potential for immunotherapy as a promising approach to managing immune exhaustion in CML patients.

Thirty five (92%) patients were treated with imatinib at diagnosis...On multivariate analysis, none of these factors were found to be significant. This retrospective study suggests that for CML CP patients achieving deep molecular response, discontinuing TKI therapy in real-world settings may be feasible while potentially achieving comparable outcomes.

The primary treatment for chronic myeloid leukemia (CML) involves first- and second-generation tyrosine kinase inhibitors (TKIs), such as imatinib, nilotinib, bosutinib, and dasatinib. It includes in silico calculations, such as the octanol/water partition coefficient (cLogP) via SwissAdme, and 2D maps of intermolecular interactions through molecular docking. This approach enhances understanding for both specialists and those interested in medicinal chemistry and pharmacology, while also contextualizing future directions for further optimizations of ponatinib, facilitating the development of new analogs of this crucial inhibitor for the treatment of CML and Philadelphia chromosome-positive acute lymphoblastic leukemia (ALL).

We report the case of a 63-year-old woman with a history of CML with poor response to imatinib who progressed to myeloid BP-CML, driven by the acquisition of t(8;21)(q22;q22)/RUNX1::RUNX1T1. The patient received intensive chemotherapy and dasatinib, followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT)...Ponatinib and azacitidine were started as salvage treatment, allowing for the achievement of complete remission with deep molecular response after five cycles. Advances in the knowledge of disease biology and clonal evolution are crucial for optimal treatment selection, which ultimately translates into better patient outcomes.

We also found that NK-128 inhibits colony formation by CD34+ CML cells isolated from the bone marrow of untreated CML patients. Taken together, these findings suggest that targeting OXPHOS is a beneficial approach to eliminating CML-LSCs, and may improve the treatment of CML.

Then we detected 6 repurposable drug molecules (Entrectinib, Imatinib, Ponatinib, Sorafenib, Retevmo, and Pazopanib) by molecular docking with KGs-mediated receptor proteins, ADME/T analysis, and cross-validation with the independent receptors. Therefore, these findings might be useful resources for wet lab researchers and clinicians to consider an effective treatment strategy against THCA.

The results showed lower expression of HOTAIR and PTGS2 in CML patients. The HOTAIR expression is inversely associated with BCR::ABL1 expression in imatinib-treated CML patients, and to PTGS2 showing that CML patients with high BCR::ABL1 expression showed reduced PTGS2 expression.
