NSCLC extracellular vesicles containing miR-374a-5p promote leptomeningeal metastasis by influencing blood‒brain barrier permeability.

ABSTRACT: Leptomeningeal metastasis (LM) is a devastating complication of advanced non-small cell lung cancer (NSCLC). Diagnosis and monitoring of LM can be challenging. Extracellular vesicles (EVs) microRNAs (miRNAs) have become a new noninvasive diagnostic biomarker. The purpose of this study was to examine the clinical value and role of EVs miRNAs in NSCLC-LM. According to next-generation sequencing (NGS), miRNAs with differential expression of EVs in serum of NSCLC patients with LM and non-LM were detected to find biological markers for the diagnosis of LM. Cellular and in vivo experiments were conducted to explore the pathogenesis of EVs miRNA promoting LM in NSCLC. In the present study, we first demonstrated the serum level of EV-associated miR-374a-5p in patients with LM of lung cancer was mu
