Figure 1. MiR-519d expression is decreased in serum and tumor tissues of NSCLC patients. (A) Serum miR-519d levels in NSCLC patients. (B) Serum levels of miR-519d in NSCLC patients of clinical stages II-III-IV. (C) The expression of miR-519d in tumor lung tissues of NSCLC patients compared to adjacent noncancerous tissues. ***p<0.001 vs. control.
