As part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2658 cancers across 38 tumor types, we integrated genes with coding and non-c
这次要和大家一起学习使用的是CAMOIP中的通路富集Pathway Enrichment分析功能。该功能主要分为两大块。一部分是GSEA分析(gene set enrichment analysis),基于ClusterProfiler包进行。另一部分是ssGSEA分析(single sample GSEA),基于GSVA包进行。我们点击左侧导航栏中的Pa...
通路的显著性分析——Pathway Enrichment Analysis 项目: 产品描述 目前,KEGG是有关Pathway的主要公共数据库。根据挑选出的差异基因,计算这些差异基因同Pathway 的超几何分布关系,Pathway 分析会对每个有差异基因存在的pathway 返回一个p-value,小的p 值表示差异基因在该pathway 中出现了富集,并计算误判率。Pathway ...

Pathway enrichment analysis helps researchers gain mechanistic insight into gene lists generated from genome-scale (omics) experiments. This method identifies biological pathways that are enriched in a gene list more than would be expected by chance. We explain the procedures of pathway enrichment analys...
barbara.tarantino@unipv.it Department of Brain and Behavioral Sciences, University of Pavia, Pavia, Italy Abstract Background: Pathway enrichment analysis is extensively used in high-throughput experimental studies to gain insight into the functional roles of pre-defined subsets of genes...
ActivePathways 2.0 extends our integrative pathway analysis framework significantly. Users can now provide directional assumptions of input omics datasets for more accurate analyses. This allows us to prioritise genes and pathways where certain directional assumptions are met, and penalise those where the ...
Because most of these methods only focused on the pathways defined in KEGG, we used KEGG pathways for this comparative analysis (details in the “Methods” section). First, accuracy was compared by using 24 gold standard data sets (Additional file 1: Table S2) [36]. We compared the RR ...
To understand the role of genes/proteins in a biological context, we can use pathway enrichment analysis (PEA), an essential method in omics research, to identify the biological role of genes/proteins. A large number of PEA methods and tools are available; nevertheless, only a few can ...
analysis (ORA) and functional class scoring (FCS) methods. FCS methods were motivated by the fact that there may be a coordinated activity in functionally related sets of genes, even though each one of them may not be deemed significantly differential by over-representation analysis. The current...
