SLNPM

SLNPM predicts interactions between long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) to elucidate regulatory relationships such as lncRNA decoy or sponge activity.

Key Features:

• Prediction output: Produces scores for potential lncRNA–miRNA interactions.
• Data integration: Integrates sequence-derived information with known interaction data to inform predictions.
• Similarity calculation: Calculates integrated similarities for lncRNA–lncRNA and miRNA–miRNA pairs.
• Combination strategies: Implements similarity-based information combination (SC) and interaction profile-based information combination (PC).
• Graph construction: Constructs similarity-based graphs for both lncRNAs and miRNAs.
• Label propagation: Applies label propagation algorithms on the constructed graphs to generate interaction scores.
• Output integration: Derives final predictions from a weighted average of outputs from the applied strategies.
• Versions: Available as SLNPM-SC (uses SC) and SLNPM-PC (uses PC).
• Performance evidence: Both versions have been reported to outperform state-of-the-art methods and to identify novel interactions in case studies.

Scientific Applications:

• Regulatory role analysis: Elucidates lncRNA roles as decoys or sponges that modulate miRNA activity.
• Disease association studies: Investigates the involvement of lncRNA–miRNA interactions in complex diseases.
• Experimental prioritization: Prioritizes candidate lncRNA–miRNA interactions for experimental validation.
• Novel interaction discovery: Identifies novel interactions for specific lncRNAs or miRNAs.

Methodology:

Calculates integrated similarities for lncRNA–lncRNA and miRNA–miRNA pairs using known interactions and sequence data via SC and PC strategies, constructs similarity-based graphs for lncRNAs and miRNAs, applies label propagation to score potential interactions, and combines outputs by a weighted average.
