Flowchart of data integration analysis. General outline of data integration, where three steps are involved: (1) mRNA, miRNA and protein omic data are standardized and merged into one matrix (joint matrix); (2) FA is done on the joint matrix to identify the tissue-specific factors, through which key molecules, including mRNAs, miRNAs and proteins, are filtered; (3) Functional analysis is performed using DAVID to extract cancer-related features.
