咱们先看图例 Expression of MCTS1 in breast cancer and non-matched normal tissues in the TCGA and GTEx databases 再来看mehods Data Collection and Processing We collected the mRNA expression profiles and clinical data of patients with breast cancer from the Cancer Genome Atlas (TCGA) database and ...
Wilcoxon Rank Sum Tests比较LUAD数据集中肿瘤组织与TCGA及GTEx正常组织之间的表达量统计学差异。Methods:TPM expressions of normal GTEx samples are paired with that in TCGA cohort (from the tcga_RSEM_gene_tpm and gtex_RSEM_gene_tpm dataset in the USCS Xena database). The data is standardized by ...
GTEx数据库的主要功能之一是研究正常人不同组织之间的基因表达区别。由于TCGA(The Cancer Genome Atlas)等数据库主要关注癌症组织的数据,对于正常组织的数据相对较少,因此GTEx数据库的加入可以使得分析结果更加准确。GTEx数据库的另一个重要功能是提供了eQTL(expression quantitative trait loci)数据,即基因表达水平受其周围...

(1)第一个部分是纯代码分析某个基因在TCGA33类肿瘤中的差异分析。 (2)结合TCGA和GTEx数据库,这样做的好处是:因为TCGA中肿瘤样本和正常样本是不均衡的,甚至某些肿瘤是没有癌旁正常组织的。所以结合GTEx数据库,可以大大增加正常样本的数量。
首先下载TCGA和GTEx数据库的TPM表达矩阵: Gene transcripts per million (TPM) data were downloaded from the UCSC Xena database, which included ACC (The Cancer Genome Atlas,n= 77) and normal samples (Genotype Tissue Expression,n= 128). 然后差异分析流程是: ...
