Among the databases and web services currently supported by rbioapi Enrichr, miEAA, PANTHER, Reactome, and STRING offer Enrichment (Over-Representation) analysis API endpoints. In this article, after a brief introduction, we will demonstrate how to perform Enrichment (Over-Representation) analysis in R, consistently and easily, using the package rbioapi.
Before continuing, note that rbioapi is an interface to the databases and web services. Hence it is the user’s responsibility to cite the services they have used. We provide suggested citations in each function’s manual. However, it is the user’s responsibility to fully and adequately cite the databases or web services used in their published research.
You can install the stable release version of rbioapi from CRAN with:
install.packages("rbioapi")However, the CRAN version is released at most once every 1-2 months, You can install the most recent (development) version from GitHub with:
install.packages("remotes")
remotes::install_github("moosa-r/rbioapi")Enrichment (Over-Representation) analysis is commonly performed when one’s analysis yields a list of genes, proteins, or other entities. We will not delve into details here and refer you to D. W. Huang et al.: Nucleic Acids Res. 37, 1 (2009) for a thorough review of the subject.
In short, to perform such analysis, in addition to some algorithms, two data are required:
A gene list which is derived from your analysis.
Gene sets, where genes are grouped based on a shared property or concept (such as pathway, role in diseases, physical location, etc.).
With over-representation analysis, you can compare your gene list to find if the member of any gene set are over-represented, meaning that they are present in your list in a manner that can not be explained by chance alone.
Many web services supported by rbioapi provide tools to perform over-representation analysis against the gene sets curated in their databases. Among the databases and web services currently supported by rbioapi, Enrichr, miEAA, PANTHER, Reactome, and STRING provide such services. Each service has a dedicated vignette article in rbioapi. Here we will focus on performing Enrichment (Over-Representation) analysis.
As a demonstration, we will use the results of Galani et al.: Nat. Immunol. 22, 32 (2021) where they have compared the gene expression of critically ill and non-critically ill COVID patients to healthy individuals. We assign a variable with 1214 differentially expressed genes (DEGs) exclusively induced in critically ill COVID patients. Next, we will see what insights we can extract from this list.

Enrichr , developed in the Ma’ayan Lab, is a service to perform enrichment analysis against a considerable number of curated gene set libraries across various species.
We have thoroughly covered performing enrichment analysis with Enrichr in the vignette article Enrichr & rbioapi. Therefore, we will only provide a brief demonstration here.
First, let us retrieve a list of available libraries in Enrichr using
the rba_enrichr_libs() function. You can find the available
Enrichr libraries in the libraryName column in the returned
data frame.
enrichr_libs <- rba_enrichr_libs()
#> Retrieving List of available libraries and statistics from Enrichr human.While the only required argument of rba_enrichr()
function is gene_list, here we use
gene_set_library argument to request an enrichment analysis
only against “KEGG_2021_Human” library.
enrichr_enrich <- rba_enrichr(gene_list = covid_critical,
gene_set_library = "KEGG_2021_Human")

multiple gene set libraries or leave it as the default parameter
NULL to perform the enrichment analysis using every gene
set library available in Enrichr. Also note that when
regex_library_name parameter is TRUE (the default value),
gene_set_library parameter will be considered as a regex
pattern, so partial matchs will be also selected.

Given the fact that proteins operate in organized units, which are the pathways, analyzing your list against Reactome pathways gene sets can provide valuable insights into the functional trajectories of your results.
You can refer to Reactome & rbioapi article for in-depth coverage of Reactome services. Here we will only demonstrate the over-representation functionality
The function rba_reactome_analysis() accepts gene lists
or a table as input. If a table is supplied, the first column should
consist of identifiers, and the next column should be numerical gene
expression values. Refer to rba_reactome_analysis()
function’s manual for details. Here, we will use our gene list of
critical COVID:
reactome <- rba_reactome_analysis(input = covid_critical)
#> Retrieving Reactome Analysis Results of your supplied Identifiers.Let us examine the response’s structure:

returned as a data frame in the pathways element. Note that
Reactome will map your provided gene identifiers and some identifiers
may not be found. Hence, keep an eye on the
identifiersNotFound element.
Naturally, you can alter the analysis parameters using the
rba_reactome_analysis() function’s arguments. The used
parameters are returned in the “summary” element.

Retrieve the analysis results:
reactome_2 <- rba_reactome_analysis_token(reactome$summary$token)In addition to the main response, you can download other data
associated with your request. see the argument request in
the rba_reactome_analysis_download() function’s manual for
more information. Here, we will download a CSV file with the input
identifiers which has not been found:
rba_reactome_analysis_download(token = reactome$summary$token,
request = "not_found_ids",
save_to = "my_analysis.csv")Reactome also generates a nice report of your analysis in pdf format, make sure to try it:

save_to = "my_analysis.pdf")PANTHER (protein analysis through evolutionary relationships) is a project that provides classification systems of genes and proteins. PANTHER also provides an enrichment service. In fact, the enrichment tool available on the Gene Ontology (GO) website is powered by PANTHER. Just like the previous sections, we will only review the enrichment functionality here; for an in-depth review of PANTHER refer to the vignette article “PANTHER & rbioapi”.
To perform the analysis, first, we need to choose the classifications (i.e., gene sets) that we want to compare our results against it. To retrieve a list of available gene sets, we call the following function:
panther_sets <- rba_panther_info(what = "datasets")
#> Retrieving available annotation datasets.The Gene Ontology (GO) project is one of the pinnacles of scientists’ collective effort in bioinformatics. The GO Consortium provides a comprehensive model of biological systems. In short, GO curates a thoroughly designed directed acyclic graph (DAG) of ontologies. You may think of it as a tree of terms, where as it branches out, the terms become more specific). Each protein may be annotated with one or more terms. The terms are organized in three domains: “Molecular Function,” “Biological Process,” and “Cellular Component”. GO slim datasets refer to subsets which are a cut-down version of GO terms. If you are not familiar with GO, I strongly encourage you to see this page and follow the links it provides: About the GO resource.
Here, we demonstrate the enrichment analysis using the Biological Process domain:
panther_enrich <- rba_panther_enrich(genes = covid_critical,
organism = 9606, #Homo sapiens
annot_dataset = "GO:0008150" #Biological Process
)

In addition to proteins interaction data, STRING also curates proteins/genes annotations and provides enrichment analysis services. You can perform the analysis against multiple gene sets. Some of the gene sets can be accessed using other services but two gene sets are exclusive to STRING. See “D. Szklarczyk et al.: Nucleic Acids Res. 49, D1 (2021)” for further information. Again. We will only review the enrichment functionality here; for an in-depth review of STRING refer to the vignette article “STRING & rbioapi”.

Parray et al.: Vaccines 9, 1056 (2021)”. They used microarray to
find differentially expressed miRNA in the severe versus mild COVID 19
patients’ blood.
covid_mirna <- c("hsa-miR-3609", "hsa-miR-199a-5p", "hsa-miR-139-5p", "hsa-miR-145-5p","hsa-miR-3651", "hsa-miR-1273h-3p", "hsa-miR-4632-5p","hsa-miR-6861-5p", "hsa-miR-6802-5p","hsa-miR-5196-5p","hsa-miR-92b-5p", "hsa-miR-6805-5p","hsa-miR-98-5p","hsa-miR-3185", "hsa-miR-572","hsa-miR-371b-5p","hsa-miR-3180", "hsa-miR-8073","hsa-miR-4750-5p","hsa-miR-6075", "hsa-let-7i-5p","hsa-miR-1231","hsa-miR-885-3p")While not necessary, we can first see what enrichment categories are available for our mature human miRNA:
