Progress in research on relationship between microRNA-7 and lung cancer / 实用肿瘤学杂志

ABSTRACT

MicroRNA-7(miR-7)was firstly found in Drosophila melanogaster,which participated in the formation of Drosophila wings,eggs and so on.In human being miR-7 is not only involved in cell prolifera-tion and differentiation,but also plays an important role in the development of tumor,especially in lung cancer. Most studies report that miR-7 is low expression in lung cancer with poor prognosis.Improving the expression of miR-7 can inhibit tumor growth.MiR-7 can regulate the expression of BCL-2,EGFR negatively,meanwhile it can regulate the sensitivity of tumor cells to radiotherapy chemotherapy and targeted therapy.Therefore,as a tumor suppressor,miR-7 is expected to become a new target for treatment of lung cancer.
