文章题目:Single cell RNA‑seq data and bulk gene profiles reveal a novel signature of disease progression in multiple myeloma 期刊:Cancer Cell International (5.8) 日期:2021.9.25 DOI:https://doi.org/10.1186/s12935-021-02190-6
文章通过重新分析MM(多发性骨髓瘤)单细胞数据集,将这些MM浆细胞分为7个cluster,并结合轨迹分析分为三个阶段(early, middle, late stage)。然后通过分析late stage的marker基因,结合其它MM Bulk RNAseq数据建立预后模型,最后做了QRT-PCR实验验证建模基因的表达情况。
文章思路
多发性骨髓瘤是由B细胞瘤引起的一种癌症,导致恶性浆细胞(表达CD138 (Syndecan-1)并参与免疫应答过程中抗体产生的细胞)产生失调和克隆、扩增 。该疾病的特征之一是骨髓中存在数量过多的异常浆细胞。
The risk score of each sample in the training set and the optimal cut-off point of risk score (− 0.34) as determined by ROC analysis were calculated and was defined as the threshold.
