miRspongeR

miRspongeR implements methods in R/Bioconductor to identify and analyze microRNA (miRNA) sponge interactions and modules—RNA entities containing multiple tandem miRNA response elements that sequester miRNAs from their target messenger RNAs (mRNAs)—to study miRNA-mediated gene regulation.

Key Features:

• Identification of miRNA sponge interactions: miRspongeR provides seven popular methodologies and an integrative approach for identifying miRNA sponge interactions.
• Validation of interactions: The package supports validation of identified miRNA sponge interactions.
• Module identification: It facilitates identification of miRNA sponge modules, i.e., groups of sponges that may share common regulatory roles.
• Functional enrichment analysis: Researchers can perform functional enrichment analysis on identified miRNA sponge modules to assess biological significance.
• Survival analysis: The tool includes survival analysis capabilities to investigate associations between miRNA sponges and clinical outcomes, including cancer.

Scientific Applications:

• Mechanistic studies: Dissecting regulatory roles of miRNA sponges in miRNA-mediated gene regulation.
• Translational research: Associating miRNA sponge modules with clinical outcomes for applications such as cancer research.

Methodology:

The package applies a combination of computational techniques that integrate multiple methods for identifying miRNA sponge interactions, using an integrative approach to apply established methodologies to new datasets.
