Given gene regions that fall in the given upstream and downstream region of mRNAs of interest, pathway enrichment analysis is carried out

Description

Given gene regions that fall in the given upstream and downstream region of mRNAs of interest, pathway enrichment analysis is carried out

Usage

geneRegionPathwayEnricher(
  region,
  org_assembly = c("hg19", "hg38", "mm10", "dre10", "rn6", "dm6", "ce11", "sc3"),
  near = FALSE,
  isTADSearch = FALSE,
  TAD = tad_hg19,
  gmtName = "",
  express = FALSE,
  isCustomExp = FALSE,
  cancer,
  exp1,
  exp2,
  label1 = "",
  label2 = "",
  isUnionCorGene = FALSE,
  databaseFile,
  isGeneEnrich = FALSE
)

Arguments

region

Bed format of input gene regions other than miRNA. Input must be Granges object.

org_assembly

Genome assembly of interest for the analysis. Possible assemblies are "mm10" for mouse, "dre10" for zebrafish, "rn6" for rat, "dm6" for fruit fly, "ce11" for worm, "sc3" for yeast, "hg19" and "hg38" for human

near

Boolean value presents whether cis-neighbourhood should be considered in the analysis

isTADSearch

Boolean value that shows whether TAD analysis is performed. This value has to be TRUE for TAD analysis.

TAD

TAD genomic regions for the species. Predefined TAD regions or any new TAD regions can be used for the analysis. TAD regions must be formated as GRanges object. Predefined TAD regions are 'tad_hg19', 'tad_hg38', 'tad_mm10', 'tad_dmel' for hg19, hg38, mm9 and dm6 assembly, respectively.

gmtName

Custom pathway gmt file

express

Boolean variable whether co-expression analysis is performed. If this option is set to TRUE, co-expression analysis will be performed.

isCustomExp

Boolean variable whether co-expression analysis with custom data will be performed. When this option is set, exp1 and exp2 parameters must be defined.

cancer

Defines the name of the TCGA project code such as 'BRCA' for correlation analysis. Possible cancer types ACC, BLCA, BRCA, CESC, CHOL, COAD, COADREAD, DLBC, ESCA, GBMLGG, HNSC, KICH, KIPAN, KIRC, KIRP, LGG, LIHC, LUAD, LUSC, OV, PAAD, PCPG, PRAD, READ, SARC, SKCM, STAD, STES, TGCT, THCA, THYM, UCEC, UCS, UVM

exp1

Custom expression data matrix. Columns must be genes and rows must be patients. If gene names are provided as header, no need to redefine the headers(labels) of the expression data.

exp2

Custom expression data matrix. Columns must be genes and rows must be patients. If gene names are provided as header, no need to redefine the headers(labels) of the expression data.

label1

Gene names of the custom exp1 expression data. If it is not provided, column name of the exp1 data will be taken.

label2

Gene names of the custom exp2 expression data. If it is not provided, column name of the exp2 data will be taken.

isUnionCorGene

Boolean value that shows whether union of the output of the co-expression analysis and the other analysis should be considered

databaseFile

Path of miRcancer.db file

isGeneEnrich

Boolean value whether gene enrichment should be performed

Value

Pathway enrichment object of the given input
