HisCoM-mimi

HisCoM-mimi performs hierarchical structured component analysis to integrate microRNA (miRNA) and messenger RNA (mRNA) data for identifying integrated molecular markers associated with phenotypes in personalized medicine.

Key Features:

• Hierarchical Structured Component Analysis: Employs a hierarchical structured component analysis approach to model indirect effects of miRNAs on phenotypes via regulation of mRNA expression and protein translation.
• Integration with Omics Data: Integrates diverse omics data generated from the same subject to detect miRNA–mRNA interactions across biological layers.
• Enhanced Marker Identification: Leverages subgroup information and network dynamics to identify more informative phenotype-associated integrated markers compared with methods lacking such integration.
• Application in Cancer Research: Demonstrated superior performance in simulation studies and real-world applications, notably identifying miRNA–mRNA integration sets for pancreatic ductal adenocarcinoma (PDAC).

Scientific Applications:

• Oncology research: Applied to cancer studies, including PDAC, to elucidate miRNA–mRNA integration relevant to disease development and progression.
• Biomarker discovery: Identifies miRNA–mRNA integration sets as candidate biomarkers for early diagnosis and prognosis.
• Therapeutic target identification: Facilitates discovery of potential therapeutic targets by revealing integrated regulatory pairs.
• Personalized medicine: Supports personalized medicine approaches by uncovering subject-specific integrated markers across omics layers.

Methodology:

Uses a statistical hierarchical structured component analysis that models indirect influence of miRNAs on phenotypes through regulation of mRNA expression and protein translation, considers both direct and indirect regulatory mechanisms, and leverages subgroup information and network dynamics.
