Results of the prospective EORTC Children Leukemia Group study 58081 in precursor B- and T-cell acute lymphoblastic leukemia. (PubMed, Hemasphere)
Dexamethasone (DXM) was used in average-risk 2 (AR2) T-ALL and B-ALL during induction, 10 and 6 mg/m2/day, respectively. Leucovorin rescue was delayed to 42 h instead of 36 h after initiation of high-dose methotrexate, and a postconsolidation MRD time point was added to stratify patients...The HR was 2.15 (99% CI: 0.67-6.85) for very low-risk but 0.34 (99% CI: 0.13-0.89) for AR2. The particularly favorable results observed in the T-ALLs and AR2 subgroups suggest the benefit of using DXM in specific patient groups and highlight the importance of risk stratification.

Treatment with a PU.1 inhibitor enhances glucocorticoid sensitivity, demonstrating the clinical potential of targeting this pathway. This study uncovers a mechanism involving PU.1 and the glucocorticoid receptor, linking transcription factor activity with drug response, and suggesting potential therapeutic strategies for overcoming resistance.

Mutations at BCL11B Exon 4 Associated with T Cell Acute Lymphoblastic Leukemia Are Facilitated by AID and Formation of Non-B DNA Conformations. (PubMed, Mol Cell Biol)
Importantly, various lines of experimentation reveal that BCL11B FR could fold into parallel G-quadruplex, triplex, and hairpin structures, which could act as a replication/transcription block, causing mutagenesis. Thus, our results suggest that AID binds to BCL11B exon 4 due to non-B DNA formation, causing U:G mismatches or replication blocks, which, when repaired erroneously, generates deleterious mutations, resulting in loss of functionality of BCL11B, and thus becomes the cause of T-ALL.

Delineating Notch1 and Notch2: Receptor-Specific Significance and Therapeutic Importance of Pinpoint Targeting Strategies for Hematological Malignancies. (PubMed, Eur J Haematol)
In this review, we emphasize the importance of distinct tissue-specific expression patterns, functional divergence, disease-specific considerations, and the necessity to minimize off-target effects that collectively underscore the significance of "individualized" targeting for Notch1 and Notch2. This comprehensive review sheds light on the receptor-specific characteristics of Notch1 and Notch2, providing insights into their roles in cellular processes and offering opportunities for developing tailored therapeutic interventions in the fields of biomedical research and clinical practice.

The third generation AKR1C3-activated prodrug, ACHM-025, eradicates disease in preclinical models of aggressive T-cell acute lymphoblastic leukemia. (PubMed, Blood Cancer J)
To exploit this finding, we developed a novel prodrug, ACHM-025, which is selectively activated by AKR1C3 to a nitrogen mustard DNA alkylating agent...ACHM-025 was significantly more effective than cyclophosphamide both as a single agent and when used in combination with cytarabine/6-mercaptopurine. Notably, ACHM-025 in combination with nelarabine was curative when used to treat a chemoresistant T-ALL PDX in vivo. The in vivo efficacy of ACHM-025 directly correlated with AKR1C3 expression levels, providing a predictive biomarker for response. Together, our work provides strong preclinical evidence highlighting the potential of ACHM-025 as a targeted and effective therapy for aggressive forms of T-ALL.

Comprehensive Genomic Profiling (CGP) of Acute Lymphoblastic Leukemias with Foundation One Heme Identifies Actionable Genomic Alterations and Biomarkers (ASH 2024)
This analysis of 2,637 samples comprising a variety of molecular subtypes of ALL demonstrated that the F1H assay detects pathogenic genomic alterations with diagnostic, prognostic, and therapeutic significance. As both the treatment landscape and disease classification system in ALL have continued to evolve over time, CGP assays such as F1H can play a critical role in clinical decision making by simultaneously assessing the presence and absence of numerous actionable genomic alterations and biomarkers with a single assay.

In contrast, late response genes, which are continuously downregulated after MYB depletion, includes many genes involved in cell proliferation as well as TAL1 targets, thereby affecting the cellular phenotype.

A dual role for PSIP1/LEDGF in T cell acute lymphoblastic leukemia. (PubMed, Sci Adv)
In cell lines, PSIP1 down-regulation leads to a reduction of COX20, an assembly factor of the cytochrome c oxidase in the mitochondria, and to a reduction in mitochondrial respiration. This indicates that PSIP1 can exert a dual role in the context of T-ALL, either as a tumor suppressor gene during tumor initiation or as a dependency factor in tumor maintenance.

Ruxolitinib combined with venetoclax and azacitidine in the treatment of refractory T-ALL patients with JAK1, JAK3, and STAT5B gene mutations: a case report and literature review (PubMed, Zhonghua Xue Ye Xue Za Zhi)
Notably, pleural effusion and mediastinal mass significantly improved the post-chest cavity infusion of dexamethasone combined with etoposide at the same stage. The patient also underwent allogeneic hematopoietic stem cell transplantation upon achieving bone marrow remission and was followed up until January 2024. Ruxolitinib combined with venetoclax and azacytidine has shown promising efficacy and safety in treating refractory T-ALL harboring the JAK1, JAK3, and STAT5B mutations, providing a novel therapeutic approach for such patients.

To sum up, our research establishes the pivotal fuction of LDB1 in the tumorigenesis and progression of T-ALL cell lines. Mechanistic insights reveal that LDB1 cooperates with ERG, ETV6, and IRF1 to modulate the expression of downstream effector genes. Furthermore, LDB1 controls MYB through remote enhancer modulation, providing valuable mechanistic insights into its involvement in the progression of T-ALL.

Unexpectedly, the CRNDE super-enhancer interacts with the IRX3 promoter with no transcriptional output until it is untethered from the FTO intronic site. We propose that 'promoter tethering' of oncogenes to inert regions of the genome is a previously unappreciated biological mechanism preventing tumorigenesis.
