This summary sheds light on novel therapies that target specific pathways. B-cell-directed therapies, phagocytosis inhibitors, complement inhibitors, and FcRn inhibitors are examples of patient-specific, pathway-oriented treatments. These innovative treatments, which are yet to be implemented in clinical settings, have the potential to enhance the management of AIHA and can be used in conjunction with other treatments that have fewer side effects than conventional therapies. In addition to their potential, methods in this emerging field also make clinical adoption challenging. Striking a balance between delivering cutting-edge care and protecting physicians' income is difficult due to the high costs. Because they maximize treatment outcomes and enable treatments to be precisely tailored to each patient's unique needs, individualized medicine and combined therapies are extremely advantageous.

We had previously established a mouse bone marrow transplantation model through the retroviral transduction of <em>RUNX1-MECOM</em>. This model demonstrated that <em>RUNX1-MECOM</em>-expressing cells developed acute megakaryoblastic leukemia and were serially transplantable. Gene expression analyses using quantitative RT-PCR arrays revealed that <em>Angpt1</em> (<em>Angiopoietin 1)</em> and <em>Tek</em> transcripts were elevated in the leukemic cells. In this study, we confirmed the concomitant expression of Angpt1 and Tek proteins in the <em>RUNX1-MECOM</em>-expressing cells. When the primary leukemic cells were stimulated with exogenous Angpt1, endogenous Tek was phosphorylated, followed by the phosphorylation of downstream Akt. Angpt1 and Tek may form a circuit of an autocrine loop and enhance leukemia cell survival. Interestingly, the expression of Tek and Angpt1 was downregulated by HDAC inhibitors (HDACi), trichostatin A (TSA) and valproic acid (VPA). Therefore, HDACi may block the Angpt1 and Tek autocrine loop. Both TSA and VPA inhibited the growth of <em>RUNX1-MECOM</em>-expressing cells <em>in vitro</em> by inducing cell cycle arrest and apoptosis. Electron microscopic analysis further indicated that partial megakaryocytic differentiation was induced after HDACi treatment. Furthermore, intraperitoneal injection with VPA, but not TSA, extended the survival of the secondary transplanted mice.

Mean (standard deviation) percentage SVR from baseline was +6.9 % (27.5 %) and −3.0 % (34.7 %) in Cohorts A and B at week 24 (primary endpoint), and −1.6 % (14.7 %) and −24.6 % (21.7 %) in Cohorts A and B at week 12. SVR from baseline was achieved by 5 and 3 patients in Cohorts A and B at week 24, and by 9 and 7 patients in Cohorts A and B at week 12. Most common treatment-emergent adverse events (TEAEs) were anemia, diarrhea, and fatigue (each n = 8); most common grade ≥ 3 TEAEs were anemia (n = 6), thrombocytopenia (n = 5), fatigue (n = 3), and diarrhea (n = 2).</div></div><div><h3>Conclusions</h3><div>Overall, 8 of 23 patients enrolled achieved SVR at week 24; larger average changes in SVR at week 12 were observed for itacitinib monotherapy vs. the combination.

However, evidence regarding the causality of circulating metabolites in promoting or preventing myelodysplastic syndrome (MDS) is currently insufficient. We conducted a bidirectional Mendelian randomization analysis (MR) to assess the causal relationship between genetically proxied 1400 blood metabolites and MDS.</div></div><div><h3>Methods</h3><div>In this study, we employed a bidirectional MR framework to explore the potential causal links between blood metabolites and the risk of MDS. Data on blood metabolites were derived from a comprehensive genome-wide association study (GWAS) dataset of European origin. Initial analyses used MDS GWAS data from the GWAS catalog. The pleiotropy, and heterogeneity analysis were applied to confirm the stability of the MR estimates.</div></div><div><h3>Results</h3><div>In a survey of 1400 metabolites, four exhibited statistical significance (P &lt; 0.05) in an inverse variance weighted (IVW) model. Levels of Alpha-hydroxyisovalerate [odds ratio (OR) = 3.157, p &lt; 0.001], Pregnenediol disulfate (C21H34O8S2) [OR = 2.805, p &lt; 0.001] and 1-linoleoyl-GPG (18:2) [OR = 2.756, p &lt; 0.001] were positively causally associated with MDS, while X-18345 [OR = 0.360, p &lt; 0.001] was negatively associated with MDS. On the contrary, MDS did not lead to significant alterations in the levels of the aforementioned four blood metabolites.</div></div><div><h3>Conclusion</h3><div>In this study, a possible causal relationship was established between four blood metabolites and MDS. Among these, three specific blood metabolites were identified as causal factors in the development of MDS and were confirmed as risk factors. Interestingly, an unknown blood metabolite emerged as a protective factor.</div></div>","PeriodicalId":18051,"journal":{"name":"Leukemia research","volume":"155 ","pages":"Article 107723"},"PeriodicalIF":2.1,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
