摘要
背景:再生障碍性贫血(AA)是一种骨髓衰竭疾病:再生障碍性贫血(AA)是一种骨髓衰竭疾病,其治疗效果的评估和预测手段仍然相对有限。血小板减少通常是新诊断为再生障碍性贫血(Dx-AA)的患者最早出现且最严重的症状。临床上通常考虑治疗过程中血小板的数量变化,但很少关注 AA 患者血小板分子特征的变化:研究AA治疗过程中血小板分子特征的变化,并探索利用转录组学监测和预测治疗结果:方法:我们利用批量转录组测序技术全面分析了AA患者在最初诊断和不同治疗效果阶段的血小板转录组变化:结果:与细胞增殖、红细胞功能和氨基酸转运相关的基因在Dx-AA中升高。相反,与组蛋白、血栓形成、线粒体能量代谢和信号通路相关的基因则明显下调。完全缓解后,60.6%的差异表达基因得到了大幅恢复。此外,通过对纵向样本的研究,我们发现了可作为评估 AA 治疗效果的生物标志物的恢复上升基因(RAG)。此外,我们还观察到,较高的 RAG 表达水平可提前 6 个月预示部分反应患者的血小板计数会有较好的长期恢复:血小板转录组发生了深刻变化,可作为评估治疗效果和预测 AA 患者血小板计数长期恢复的潜在指标。
Application of platelet transcriptomics for assessing treatment effectiveness and predicting long-term platelet counts recovery in aplastic anemia.
Background: Aplastic anemia (AA) is a bone marrow failure disease for which the means of assessing and predicting the therapeutic effectiveness are still relatively limited. Thrombocytopenia is often the earliest and most severe symptom in patients newly diagnosed with AA. While clinical consideration is usually given to the quantitative changes in platelets during treatment, there is little focus on the resolution of the molecular characteristics of platelets in AA.
Objectives: To investigate the changes in platelet molecular characteristics throughout the treatment process of AA, and to explore the use of transcriptomics for monitoring and predicting treatment outcomes.
Methods: We comprehensively analyzed platelet transcriptomic changes in patients with AA at initial diagnosis and different stages of treatment effectiveness using bulk transcriptome sequencing.
Results: Genes associated with cell proliferation, erythroid function, and amino acid transport were elevated in newly diagnosed AA. Conversely, genes linked to histones, thrombopoiesis, mitochondrial energy metabolism, and signaling pathways were significantly downregulated. Additionally, 60.6% of the differentially expressed genes were substantially restored following complete remission. Furthermore, through the examination of longitudinal samples, we identified recovery ascending genes that could serve as viable biomarkers for assessing treatment effectiveness in AA. Besides, we observed that higher expression levels of recovery ascending genes may predict superior long-term platelet counts recovery 6 months in advance in patients with partial response.
Conclusion: The platelet transcriptome undergoes profound changes and can serve as a potential indicator for assessing treatment effectiveness and predicting long-term platelet counts recovery in AA.
