📊 Overview

Integrate Analysis and Visualization for Bioinformatic Enrichment Analyzer

BioEnricher lies in addressing two issues: firstly, it facilitates the seamless integration for enrichment analysis, encompassing diverse functionalities such as GO, KEGG, WikiPathways, Reactome, MsigDB, Disease Ontology, Cancer Gene Network, DisGeNET, CellMarker, and CMAP (drugs); infers the activities of transcription factors and PROGENy cancer pathways; searches the gene information, PubMed records and GEO metadata based on the input terms; secondly, it encapsulates advanced visualization functions, streamlining the process for faster and more convenient data presentation.

🔰 Examples

Get an interested gene list (for ORA) or an order-ranked geneList (for GSEA)

You should identify an interested gene list or an order-ranked geneList by employing differential analysis or other methods.

library(airway)
library(DESeq2)
library(tidyverse)
library(clusterProfiler)
library(org.Hs.eg.db)
data(airway)
se <- airway
se$dex <- relevel(se$dex, "untrt") 
res <- DESeqDataSet(se, design = ~ cell + dex)%>%
  estimateSizeFactors()%>%DESeq()%>%
  results()%>%as.data.frame()%>%na.omit()
ann <- bitr(rownames(res),'ENSEMBL','SYMBOL',org.Hs.eg.db)
res <- merge(ann,res,by.x=1,by.y=0)%>%distinct(SYMBOL,.keep_all = T) # Very crude, just as an example

# Define an up-regulated gene list
up.genes <- res$SYMBOL[res$log2FoldChange > 2 & res$padj < 0.05]
# Define a down-regulated gene list
down.genes <- res$SYMBOL[res$log2FoldChange < -2 & res$padj < 0.05]

You can get a list of enrichment methods BioEnricher can perform:

listEnrichMethod()
# "GO", "KEGG", "MKEGG", "WikiPathways", "Reactome", "MsigDB", "DO", "CGN", "DisGeNET", "CellMarker", "CMAP"

📎 ORA

# Set enrich.type using an enrichment analysis method mentioned above.
kegg <- lzq_ORA(
  genes = res$SYMBOL[res$log2FoldChange > 0 & res$padj < 0.05],
  enrich.type = 'KEGG'
)

# This function will output its calculation process.
