The emerging role of miR-19 in glioma

Glioma has been regarded as the most common, highly proliferative and invasive brain tumour. Advances in research of miRNAs in glioma are toward further understanding of the pathogenesis of glioma. MiR-19, a member of miR-17 similar to 92 cluster, was reported to play an oncogenic role in tumourigenesis. Here we review the identified data about the effect of miR-19 on proliferation, apoptosis, migration and invasion of glioma cells, the target genes regulated by miR-19, and correlation of miR-19 with the sensitivity of glioma cells to chemotherapy and radiotherapy. It is concluded that miR-19 plays an important role in the pathogenesis of glioma and can be a potential target for gene therapy of glioma.
