We demonstrate how one may use seqgendiff in differential expression simulation studies using the airway data from Himes et al (2014). We use seqgendiff to simulate one dataset which we then analyze with two pipelines: the sva-voom-limma-eBayes-qvalue pipeline, and the sva-DESeq2-qvalue pipeline.

Such modeling of count data is well known (see Robinson et al. 2010; McCarthy et al. 2012; Wu et al. 2013; Law et al. 2014; Zhu et al. 2024). Based on that assumption, we calculate gene-specific z-scores for every count in the matrix. ibis ownerWebFurthermore, we found that STC2 promoted cell migration and invasion in vitro. And a group of differentially expressed genes, which were modulated by STC2, were identified from RNAseq analyses. Conclusion: Our study demonstrates that STC2 is overexpressed in CRC compared with normal tissues, and promotes CRC cell migration and invasion. monastery trappistWebA workflow for single cell RNA-seq data analysis - Fred Hutch ibispaint accountWebDESeq2 is an R package for analyzing count-based NGS data like RNA-seq.
