The addition of total marrow irradiation (TMI) to myeloablative conditioning provides an opportunity to increase intensity with minimal additional toxicity. In this phase 2 clinical trial, 30 patients with high-risk myeloid malignancies received an allogeneic HSCT using myeloablative TMI at 9Gy in combination with standard myeloablative fludarabine/intravenous busulfan (FluBu4) chemotherapy. The study included patients with matched-related donors (n=10) receiving TMI/FluBu4 and patients with matched unrelated (n=14) or 1-antigen mismatched unrelated (n=6) donors receiving TMI/FluBu4 and rabbit antithymocyte globulin. All patients achieved sustained engraftment. Grade 3-4 extramedullary toxicities were: mucositis in 59% (n=17), nausea/vomiting in 10% (n=3) and diarrhea in 7% (n=2) of the patients. Acute graft-versus-host disease (GVHD) grade III-IV was seen in 4 patients (13.3%). Moderate/severe chronic GVHD was observed in 11 patients (36.7%). With a median follow-up of 1483 days (range: 63-2260 days) for patients alive, the overall survival and disease-free survival at 1 year were 72.4% and 65.5%, respectively.

Of 30 patients in the study, 6 relapsed/progressed (20%) and 5 of them died of the disease (16.7%); whereas 6 patients (20%) died of transplant-related mortality.

Although 5-hydroxytryptamine receptor 7 (5-HTR7) has been implicated in megakaryocyte (MK) biology, its pathogenic involvement in ITP is undefined. This study investigated the impact of 5-HTR7 on MK maturation in ITP using flow cytometry, immunofluorescence, and single-cell RNA sequencing (scRNA-seq). Analyses revealed elevated 5-HTR7 expression on MKs from ITP patients compared to healthy controls. Pharmacological inhibition of 5-HTR7 using SB269970A not only rescued MK maturation defects in vitro but also restored circulating platelet levels in a mouse model of active ITP. scRNA-seq coupled with western blot validation identified ERK1/2 phosphorylation in SB269970A-treated MKs. Mechanistically, 5-HTR7 impaired MK maturation through the PKA/Orai1/ERK axis by suppressing store-operated calcium entry (SOCE), as confirmed via confocal microscopy. In conclusion, elevated expression of 5-HTR7 impairs maturation of MKs causing lower platelet count in ITP, offering a potential therapeutic target for ITP management.","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":"5 1","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we tested the activity of a novel PI3Kδ selective, non-ATP competitive inhibitor, roginolisib (IOA-244), in hematological malignancies including diffuse large B cell lymphoma (DLBCL) and chronic lymphocytic leukemia (CLL). To identify rational actionable combination partners that can be tested in hematologic malignancies, an unbiased pharmacological screening of 474 compounds was carried out in two lymphoma cell lines. We identified BCL2 blockade with venetoclax as synergistically active with roginolisib, a finding confirmed in a broad panel of lymphoma cell lines, DLBCL cell lines and primary CLL samples. We further demonstrate that the sensitizing effects of roginolisib to venetoclax correlate with suppression of downstream PI3K/AKT pathways and alterations in the expression of the apoptotic proteins BIM, mediated through FOXO1 transactivation, and MCL1, with ubiquitination and degradation mediated through GSK3α/β activation. These findings support proof of concept for roginolisib development in hematological malignancies as a single agent or in combination with venetoclax.

Bone marrow metrics, including marrow cellularity, the myeloid-to-erythroid (M: E) ratio, megakaryocyte morphology and distribution, and the grading of marrow fibrosis (MF), were quantitatively analyzed (with an accuracy of approximately 0.9) based on the accuracy segmentation and identification of various cells and tissues (with an intersection over union (IoU) of roughly 0.8).

The bone marrow and comprehensive classification models reached a macro-average area under the curve (AUC) of 0.96 for differentiating MPN subtypes and nonneoplastic cases. The clinical classification model attained a macro-average AUC of 0.92.
