Abstract

The aim of the present study was to investigate the effects of microRNA‑18a (miR‑18a) on the invasiveness and metastasis of invasive meningiomas and the underlying mechanism. A total of 69 patients with meningiomas (30 patients in the invasive meningioma group and 39 patients in the non‑invasive meningioma group) and 48 cases in the control group were enrolled. Samples of meningioma tissues, serum and cerebrospinal fluid were collected. Reverse transcription‑quantitative polymerase chain reaction was performed to quantify the expression levels of hypoxia‑inducible factor‑1α (HIF‑1α) mRNA and miR‑18a. Western blot analysis was used to determine protein expression levels of HIF‑1α. The expression levels of HIF‑1α mRNA and protein in all three types of sample from the invasive meningioma group were significantly higher compared with those in the control and non‑invasive meningioma groups (P<0.05), and the expression levels of HIF‑1α mRNA in the serum and cerebrospinal fluid of the non‑invasive meningioma group were significantly higher compared with those in the control group (P<0.05). The expression levels of miR‑18a in the invasive meningioma group were significantly reduced compared with those in the control and non‑invasive meningioma groups (P<0.05), whereas the levels of miR‑18a in the non‑invasive meningioma group were significantly lower compared with those in the control group (P<0.05). The expression of HIF‑1α is significantly upregulated in patients with invasive meningiomas, possibly due to the downregulation of miR‑18a expression. Therefore, miR‑18a may regulate invasive meningiomas via HIF‑1α.
