Abstract

The present study aimed to investigate the roles of the vascular endothelial cell growth factor (VEGF) and micro (mi)RNA‑210 in the metastasis of primary medulloblastoma (MB) tumors. A total of 86 adult patients diagnosed with cerebellar MB were enrolled in the present study, of which 11 patients had metastatic MB in the subarachnoid space. The following samples were collected: MB primary tumor tissue, MB secondary tumor tissue, tumor adjacent tissues and cerebrospinal fluid (CSF). Immunohistochemical analyses of the tissue samples were conducted in order to detect patterns of VEGF expression. In addition, the expression levels of VEGF mRNA and miRNA‑210 were analyzed using reverse transcription‑quantititative polymerase chain reaction, and western blot analyses were used to investigate VEGF protein expression levels. The positive expression rate of VEGF was significantly higher in MB tumor tissue, as compared with adjacent tissues (P<0.01). In addition, VEGF mRNA and protein expression levels in MB primary and secondary tumor tissues, and in the CSF of patients with metastatic MB, were significantly upregulated, as compared with tumor adjacent tissues and the CSF of patients with non‑metastatic MB, respectively (P<0.01). miRNA‑210 expression levels were significantly upregulated in MB tumor tissues, the CSF of patients with metastatic MB and in tumor tissues of metastatic MB (P<0.01). In the present study, the expression levels of VEGF and miRNA‑210 were upregulated in patients with MB and metastatic MB; thus suggesting that miRNA‑210 may promote the metastasis of MB primary tumors by regulating the expression of VEGF.
