miR-655 is a widely studied non-coding small RNA molecule. miR-655 is down-regulated in at least 15 cancers and up-regulated in acute myeloid leukemia (AML) and breast cancer (BC) cell lines. The expression level of miR-655 is closely related to the prognosis of cancer patients. In addition, we summarize all genes that can be down-regulated by miR-655 in cancer. In breast cancer, we also found the upstream regulatory pathway of miR-655. Here, we systematically analyze biological pathways and molecular functions of the miR-655-related genes. Our results indicate that miR-655-related genes are involved in cancer cell proliferation, migration, invasion, and apoptosis, and various biological processes such as angiogenesis, EMT, and oxidative stress. miR-655 may also affect the efficacy of many drugs through its targeted genes. This review summarizes the related research of miR-655 in various diseases and evaluates its potential application as a molecular marker for diagnosis and prognosis.
