Cancer is among the leading cause of deaths in men and women today. Regulation of gene expression by microRNAs (miRNA) has been linked to cancer progression in recent years. Therefore there has been a growing interest understanding how miRNAs mediate gene expression in cancer. In this dissertation we aimed to construct an integrative miRNA-gene network to understand how miRNAs affect gene expression and their downstream genetic neighborhoods in ovarian cancer and colon cancer. To conduct this research, we applied different techniques to determine how miRNAs impact downstream genetic neighborhoods and identify cancer enriched neighborhoods in ovarian and colon cancer. First, we developed a community based method utilizing the spin-glass model to construct an integrative miRNA-gene network. Second, we developed a label propagation framework to construct a multi-layer miRNA-gene network to exploit the downstream effects of miRNAs throughout integrating multiple networks. We identified multiple communities enriched in cancer-driven pathways across multiple networks in ovarian cancer. We also uncovered enriched genetic neighborhoods and identified key network signatures in patients with different pathological stages in colon cancer. The methods developed provide a better outlook on how miRNAs affect gene expression and their downstream genetic neighborhoods, which will improve our understanding of their role in tumorigenesis and cancer progression.
