A software for inferring cancer-related miRNAs based on gene expression data. It is a novel computational framework to identify the cancer-related miRNAs based solely on gene expression profiles which can effectively identify cancer-related miRNAs with higher precision compared with other popular approaches. Given the gene expression data, miR_Path can infer cancer-related miRNAs which are validated by both differentially expressed miRNAs and evidences from literature. miR_Path provides a useful tool to explain how miRNAs are involved in cancer.
