MicroRNA-378 is associated with non-small cell lung cancer brain metastasis by promoting cell migration, invasion and tumor angiogenesis

摘要
Lung cancer is the leading cause of cancer deaths in the world. Brain metastasis (BM) can affect about 25% of non-small cell lung cancer (NSCLC) patients during their lifetime. Efforts to characterize patients that will develop BM have been disappointing. MicroRNAs (miRNAs) play a role in regulating a variety of targets and, consequently, multiple pathways, which make them a powerful tool for early detection of disease, risk assessment and prognosis. In this study, using RT-PCR and further northern blot validation, we confirmed that miR-378 was significantly differentially expressed in the matched NSCLC from 8 patients with BM and 21 without BM. Our study showed evidences that miR-378 is associated with non-small cell lung cancer brain metastasis by promoting cell migration, invasion and tumor angiogenesis. MiR-378 may be a potential biomarker for characterizing non-small cell lung cancer brain metastasis and assisting clinicians in stratifying the high-risk patients on a clinical trial for either prophylactic cranial irradiation or a new intervention that may mitigate BM development, ultimately leading to a new standard of care for NSCLC patients.
