[Research Progress on miR-125 Family in Malignant Hematologic Diseases-Review].

MicroRNAs (miRNAs) are a class of endogenous non-coding single-stranded small noncoding RNAs with the length of 20 to 23 nucleotides. MicroRNA-125 (miR-125) family, which is a highly conserved miRNA family, is consist of miR-125a, miR-125b-1 and miR-125b-2. Accumulating evidence demonstrated that miR-125 can be involved in various physiological and pathological processes in vivo. Importantly, it is closely related with the tumorigenesis and tumor development, including tumor cell proliferation, apoptosis, invasion and metastasis, metabolism and immune response. In malignant hematologic diseases, it is defined either as a oncogene, or as a tumor suppressor gene, even, closely related with the drug resistance in a variety of hematologic malignancies. MiR-125 is expected to become a new therapeutic target. Newly, the research of the relationship between miR-125 family and hematologic malignancies become increasing, including leukemia, lymphoma, multiple myeloma. In this review, the relationship between miR-125 family with malignant hematologic diseases and its latest research progress are summarized.
