The results demonstrated that both paired difference and unpaired difference analysis of SLC6A8 in NSCLC showed statistical significance, and SLC6A8 expression was significantly higher in tumor tissues than in paraneoplastic (Figure 2A–E; P-value<0.05) or normal tissues (Figure 2F–I; P-value<0.05). The gene discussed is SLC6A8; the disease is non-small cell lung carcinoma.
