一个30个基因的分类器区分低风险MDS HSPCs和健康HSPCs。
骨髓增生异常综合征(MDS)是一组以造血功能障碍、形态发育不良和遗传异质性为特征的恶性克隆性疾病1。低风险MDS (LR-MDS)包括IPSS-M患者,中低风险、低风险和极低风险2,中位生存期有限,为3至10年3。此外,人们对发现LR-MDS病理生理的翻译靶点越来越感兴趣。造血干细胞和祖细胞(HSPC)到骨髓分化谱内的克隆群体被广泛认为是MDS病理生理的主要贡献者4。对导致LR-MDS病理生理的细胞类型和谱系特异性状态的颗粒评估仍有待阐明。在这里,我们利用单细胞转录组学来表征LR-MDS中hspc -髓细胞分化景观的细胞状态。我们开发了一个30基因评分来分类LR-MDS的HSPCs,并确定了LR-MDS的新分子特征。我们评分中的基因提示水疱运输功能障碍,我们进一步解决了骨髓分化轴。囊泡运输相关途径的基因产物可能是LR-MDS合适的翻译靶点。摘要:我们利用单细胞转录组学来区分来自患者骨髓样本的低风险MDS细胞和健康细胞。采用网络分析和分类相结合的方法鉴定了30个基因特征,将MDS HSPCs与HD HSPCs区分开来。观察到与蛋白质翻译,促炎细胞因子产生和囊泡运输相关的途径上调。最后,我们根据hspc -髓细胞分化轴上的表达对这30个基因进行了分类,并强调了与囊泡运输成分相关的基因的不同表达模式。

期刊介绍: Experimental Hematology publishes new findings, methodologies, reviews and perspectives in all areas of hematology and immune cell formation on a monthly basis that may include Special Issues on particular topics of current interest. The overall goal is to report new insights into how normal blood cells are produced, how their production is normally regulated, mechanisms that contribute to hematological diseases and new approaches to their treatment. Specific topics may include relevant developmental and aging processes, stem cell biology, analyses of intrinsic and extrinsic regulatory mechanisms, in vitro behavior of primary cells, clonal tracking, molecular and omics analyses, metabolism, epigenetics, bioengineering approaches, studies in model organisms, novel clinical observations, transplantation biology and new therapeutic avenues.
