The mean AXL score was higher in the lung cancer cohort than in the normal cohort (217.9 ± 37 vs 120.8 ± 29.9, P < 0.01) (Fig. 7c), whereas the mean PTBP1 H-score was lower in the lung cancer cohort than in the normal cohort (57.8 ± 17.8 vs 116.7 ± 22.4, P < 0.01) (Fig. 7d). This evidence concerns the gene PTBP1 and lung carcinoma.
