安排学徒复现一个新鲜出炉的阿兹海默症的单细胞文章:《Characterisation of premature cell senescence in Alzheimer’s disease using single nuclear transcriptomics》: Acta Neuropathologica (2024) https://doi.org/10.1007/s00401-024-02727-9 对应的数据集是:GSE264648,大家很容易读取作者提供的表达量矩阵然后进行降维聚类分群。值得注意的是作者重点看了看 the ‘canonical senescence pathway (CSP)’, the ‘senescence initiating pathway (SIP)’ 这两个基因列表在单细胞亚群的差异情况,如下所示: 两个基因列表在单细胞亚群的差异情况 左边的气泡图很容易理解,也很容易复现,在前面的降维聚类分群结果的基础上面进行: # 创建基因向量 gene_vector "ABL1", "AKT1" , "ALDH1A3" , "ATM" , "BMI1" , "CCND1" , "CDK6" , "CDKN1A" , "CDKN1B" , "CDKN1C" , "CDKN2A" , "CDKN2D" , "CHEK2" , "CITED2" ,
