FGFR1 and lung cancer: Quantitative real-time PCR (qRT-PCR) demonstrated a lower expression of miR-214-3p in the tumor tissues of lung cancer (n = 30) than in non-tumor adjacent tissues (NATs) (Fig. 1a), while immunohistochemistry (IHC) showed a higher FGFR1 level in the tumor tissues of lung cancer than in the NATs (Fig. 1d).
