EGFR and non-small cell lung carcinoma: Moreover, miR-193a-3p expression was remarkably decreased in NSCLC patients with high expression of epidermal growth factor receptor (EGFR) protein (3.1588 ± 1.8426), when compared with those with low EGFR protein expression (4.6058 ± 2.4525, P = 0.034, Fig. 2d).
