WebFeb 16, 2024 · approach is the pseudo-bulk aggregation, which transforms scRNA-seq data into bulk-like data by aggregating gene counts within each cell type and subject. Both approaches have previously been shown to reduce the number of false positives [6,8–10]. … WebJan 27, 2024 · Overall, 329 DEGs were selected for prognostic model construction through differential analysis and WGCNA. Besides, NMF identified two clusters based on DEGs in the TCGA cohort, with distinct prognosis and immune characteristics being observed. We developed a prognostic model based on the expression levels of six DEGs.
WebMar 25, 2024 · Methods for differential expression analysis can be divided into four categories: ( A) Traditional bulk DE analysis methods (e.g. DESeq2 and edgeR) compare cases with controls from bulks of cells. The expressions are represented as per gene, per individual; cell type is ignored.
