Pseudobulk correlation analysis
WebA balanced measure shows superior performance of pseudobulk methods over mixed models and pseudoreplication approaches in single-cell RNA-sequencing analysis. bioRxiv 2024 GagnonJ, et al. Recommendations of Scrna-Seq Differential Gene Expression Analysis Based on Comprehensive Benchmarking. WebJun 23, 2024 · One strategy for simplifying the analysis of scRNA-seq data is to construct pseudo-bulk data. If we have molecule counts generated using scRNA-seq for genes measured in cells , belonging to different groups denoted by indicator variables , then this approach constructs new data .

WebApr 7, 2024 · Detection of cellular and genetic correlates of SLE. Genetic multiplexing enabled single-cell profiling of hundreds of individuals with and without SLE. These profiles revealed that SLE patients exhibit changes in cell composition and cell type–specific gene expression, which were used to model disease status and severity.
WebFeb 19, 2024 · Our analysis demonstrates that pseudobulk approaches are the best performing across all number of individuals and cells variations (Figure 1). There is one exception for sum pseudobulk which performs worse than Tobit at 5 individuals and 10 cells. Figure 1 also 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.
WebNov 22, 2024 · The term bivariate analysis refers to the analysis of two variables. You can remember this because the prefix “bi” means “two.” The purpose of bivariate analysis is to understand the relationship between two variables.
