Over the past few years, many different studies have attempted to utilize the miRNA-disease association to identify novel miRNAs that show association with different types of cancer. For example, L. Li and coauthors developed a miRNA-cancer association database, miCancerna, which used text-mining to find thousands of miRNA-cancer associations from current studies published . Another study used a Gaussian Bayesian network to analyze relationships between genes and miRNAs, which provided information of significant genes in cancer-related pathways .
