miRBaseConverter is an R/Bioconductor package for converting and retrieving the definition of miRNAs ( Names, Accessions, Sequences, Families and others) in different miRBase versions ( From miRBase version 6 to version 21 [ The latest version ] ). A tiny built-in database is embedded in the miRBaseConverter R package for retrieving miRNA information efficiently.
microRNAs( miRNAs) are one of the essential molecules that play the important role in the post-transcriptional gene regulation. The studies about novel miRNA and their function discoveries have an explosive growth in the last decade. The miRBase database is the authority archive of miRNA annotations and sequences for all species. With the development of researches about miRNAs, the annotation of miRNA has been changed significantly and develops many different historical versions. Each of the previous versions has been adopted in many research literatures and databases. Due to the inconsistent of name annotation of miRNAs, there is a barrier for the later scholars to reuse the previous research results in a convenient way, especially for miRNA databases with thousands of entries. There are some webservers or R-based tools can handle the batch conversion of miRNA names. However, an easy-to-use and well-documented tool for miRNA conversion and information retrieval is still lack. We present the miRBaseConverter R package, a comprehensive tool for miRNA research, to provide a suite of tools for checking miRNA Name, Accession, Sequence, version and family and history information. The miRBaseConverter package can be competent for all species including Precursor and Mature miRNAs defined in miRBase.
In addtion, we also develop an online application with interactive interface for this package which can be accessed in https://taoshengxu.shinyapps.io/miRBaseConverter/.
In the following sections, we present the detail usage of the functions included in the miRBaseConverter package.
For a list of miRNA names without version information, users may need to check what is the most possible miRBase version. miRBaseConverter package provides an easy-to-use function checkMiRNAVersion()
to address this issue with an straightforward result.
library(miRBaseConverter)
data(miRNATest)
miRNANames = miRNATest$miRNA_Name
version=checkMiRNAVersion(miRNANames, verbose = TRUE)
## Version Proportion Recommend
## 1 v6 12.33%
## 2 v7_1 18.67%
## 3 v8 18.83%
## 4 v8_1 20.33%

## 20 v20 82.83%
## 21 v21 78.5%
The output text in console shows the matched proportions in all the miRBase version and gives the recommended version which is the best matched with the highest proportion values. This function is of great helpful miRNA version checking of a chunk of miRNAs.
An Accession is the identifier that define miRNA uniquely in miRBase. Users can apply Accessions to retrieve the entire information of the miRNAs in miRBase. One of the most commonly used functions is to retrieve the corresponding miRNA name from Accession. The manual retrieval one by one in miRBase could be a tough work for a chunk of Accessions of interest. The function miRNA_AccessionToName()
in miRBaseConverter package can conduct a high throughput transformation within quite short time.
library(miRBaseConverter)
data(miRNATest)
Accessions = miRNATest$Accession
#### 1. Convert to the Accessions to miRNA names in miRBase version 13
result1 = miRNA_AccessionToName(Accessions,targetVersion = "v13")
result1[c(341:345),]

## 345 MIMAT0011111 <NA>
####2. Convert to the Accessions to miRNA names in miRBase version 21.
result2 = miRNA_AccessionToName(Accessions,targetVersion = "v21")
result2[c(341:345),]

The conversion of miRNA Name to Accession is the reversion process. Due to the frequent changes of miRNA name in different versions, researches are likely to adopt the miRBase Accessions as the identifiers in most literatures and databases.
library(miRBaseConverter)
data(miRNATest)
miRNANames = miRNATest$miRNA_Name
result1 = miRNA_NameToAccession(miRNANames,version = "v18")

In miRBaseConverter package, there are two ways to conduct the conversion of miRNA Names between two different miRBase versions.
miRBaseConverter package provides the miRNAVersionConvert()
function to detect all the match miRNA Names with the same Accession in all miRBase historical versions. The conversion result may not match to the unique Name for some miRNAs but it is useful for all possible information retrieval for the miRNAs of interest.
library(miRBaseConverter)
data(miRNATest)
miRNANames = miRNATest$miRNA_Name
result1 = miRNAVersionConvert(miRNANames,targetVersion = "v13",exact = TRUE)

The miRBase Accession can be a bridge to exactly match miRNA Name between two different miRBase versions. For a group of miRNA Names, users could apply the function checkMiRNAVersion()
to check the possible miRNA version firstly. Then the miRNA Names accompanying with the version information are mapped to the Accessions using the function miRNA_NameToAccession()
. In the last step, the Accessions can be easily mapped to the miRNA Names in the target version. This approach can output more exact result than the global searching and matching.

A Precursor miRNA is about 70mer RNA with a stem-loop to form as a hairpin structure. The 5’ UTR and/or 3’ UTR of the stem-loop can be cleaved by dicer to generate one or two mature miRNAs ( about 22 nucleotides ). In miRBaseConverter package, we provide the functions for conversion between precursors and mature miRNAs.

miRNAs are manually classified by the single-linkage method to cluster the precursor sequences based on BLAST hits and adjusted manually the clustered families by multiple sequence alignment in miRBase. The family classification is based on a common ancestor for each family representing sequences. Normally, the miRNAs from the same family may possess similar physiological functions in cell metabolism. In miRBaseConverter package, the function checkMiRNAFamliy()
is specifically designed for the retrieval information of miRNA families. It can be applied to retrieve the miRNA families and family accessions for a list of miRNAs.

Currently, the latest miRBase version is 21 which was released in June 2014. In miRBaseConverter package, we implement a query function to check all the miRBase version information from miRBase version 1 to version 21. The return includes the information of the defined version names, release dates, the number of defined miRNAs (Entries including Precursors and Mature miRNAs) and the available status in miRBaseConverter package.

There is a data table for presenting the detailed information of the defined miRNAs in each miRBase version. In miRBaseConverter package, we provide a function getMiRNATable()
to return the miRNA data table for each miRBase version. Meanwhile, users can use the control parameter to custom the species in output.
library(miRBaseConverter)

The R/Bioconductor package miRBaseConverter provides a suite of tools for checking miRNA Name, Accession, Sequence, Species, Version, Hisotry and Family information in different miRBase versions. We wish that the miRBaseConverter package could be a useful tool for miRNA research community and help to speed up the studies of miRNAs.
