Over the past 10years, gene set analysis has been the first option for studying gene expression and gene interaction for gaining insights into the fundamental dynamic biology of disease/traits. It, therefore, reduces the complexity of traditional statistical research and increases the illustrating ...

Gene Set/Pathway enrichment analysis is one of such techniques; a step-by-step instruction is described in this chapter. 展开 关键词: Gene set enrichment analysis Pathway enrichment analysis GO term analysis Overrepresentation analysis Biomarker ...
GSEA(Gene Set Enrichment Analysis; 基因集合富集分析) 富集是将一组基因根据一些先验的知识(也就是常见的注释)进行分类的过程。也就是物以类聚。我们一般会想到最常见的是GO/KEGG(pathway)富集,其思路是先筛选差异基因(也就是不同的处理后基因组里发生表达变化的那些基因。如果培养条件没有发生变化,那么细胞在短...
We similarly defined true positives for the KEGG pathways by identifying all pathways belonging to the following categories: immune system, immune disease, signal transduction, signaling molecules, and interaction (https://www.genome.jp/kegg/pathway.html). The second approach we took to evaluate the...

Differential expression (DE) analysis and gene set enrichment (GSE) analysis are commonly applied in single cell RNA sequencing (scRNA-seq) studies. Here, we develop an integrative and scalable computational method, iDEA, to perform joint DE and GSE anal
The hybrid lipoplex induces cytoskeletal rearrangement via autophagy/RhoA signaling pathway for enhanced anticancer gene therapy Delivering plasmid DNA to solid tumors is challenging since it demands more transport steps than other genetic materials. Here this group designs a hybrid lipoplex for co-deliveri...
14.1Introduction This lecture introduces the notion of enrichment analysis,where one wishes to assign bio-logical meaning to some group of genes.Whereas in the past each gene product was studied individually to assign it functions and roles in biological processes,there now exist tools that allow ...
