Significant correlation was found between LAT1 expression and Ki-67 labelling index (Spearman's rank correlation coefficient γ=0.772, P<0.001) in NSCLC (AC (γ=0.5817, P<0.001), SQC (γ=0.6917, P<0.001), and (LCC (γ=0.7947, P<0.001)) (Figure 3). This evidence concerns the gene SLC7A5 and non-small cell lung carcinoma.
