Serum exosomal <scp>miR</scp>‐1269a serves as a diagnostic marker and plays an oncogenic role in non‐small cell lung cancer

Taken together, our study identified a panel of four serum exosomal miRNAs as a potential noninvasive diagnostic biomarker for NSCLC. The interactions between FOXO1 and miR-1269a represent novel potential targets for NSCLC therapy.
