Abstract

Glioma is a primary brain tumor driven from abnormal growth of poorly differentiated or anaplastic glial cells. Many studies have shown that upregulated expression of miR-20a is related to disease progression, poor survival and high mortality of glioma. This study aimed to evaluate miR-20a expression level in the peripheral blood of glioma patients after surgery. The expression level of miR-20a of 62 post-operative gliomas and 62 healthy controls was quantified by Realtime-PCR technique. The results showed that miR-20a expression level was significantly lower in the glioma group (0.264 ± 0.342) than that in control group (0.659 ± 0.841) (p < 0.001). This data suggests a relation between the decrease of miR-20 expression level and glioma.
