Abstract：Malignancy is one of the important factors leading to human death. The occurrence of malignant tumors is closely related to the abnormal expression of a particular gene. MicroRNA-125b (miR-125b) is a non-coding small RNA molecule that plays a pivotal role in different biological changes. More and more studies have shown that miR-125b may be an advanced biomarker for the diagnosis of certain specific malignancies and may be a potential new target for its medical treatment. According to the latest research results of the relationship between miR-125b and tumor, it is reviewed in the aspects of cell proliferation, apoptosis, invasion and metastasis and drug resistance.
