Pseudobulk correlation analysis
WebOct 16, 2024 · Pseudobulk DE analysis using edgeR. This markdown takes as input a Seurat object post-clustering. This assumes a pairwise analysis (i.e. comparison between to two groups) and that you have replicates for each group. The clusters in this markdown are simply numbered, but you can use celltype labels if you have just update the appropriate … WebPseudo-bulk functional analysis When cell lineage is clear (there are clear cell identity clusters), it might be beneficial to perform functional analyses at the pseudo-bulk level instead of the single-cell. By doing so, we recover lowly expressed genes that before where affected by the “drop-out” effect of single-cell.

WebApr 13, 2024 · Take Celltype A and Disease A for example. I used the sum raw counts for this cell type and individual as a pseudobulk expression and generated the expression matrix. For filtering, I removed samples if there were less than 50 cells per sample. I filtered genes if the row sum is smaller than 10.

WebApr 7, 2024 · For each pseudobulk, we calculated the relative expression of the aforementioned 48 marker gene sets using Seurat’s (v4.0.4) AddModuleScore function with the default parameters. The gene set expression matrix was then used as input for Pearson correlation analysis.

WebMar 29, 2024 · Performing pseudo-bulk DGE enables us to reuse well-tested methods developed for bulk RNA-seq data analysis. Each pseudo-bulk profile can be treated as an in silico mimicry of a real bulk RNA-seq sample (though in practice, it tends to be much more variable due to the lower numbers of cells).
