The mean BCHE levels of the control and NSCLC groups were 4.87 ± 1.27 μg/mL and 3.91 ± 1.17 μg/mL, respectively (p < 0.05); the GPx3 levels of the control and NSCLC groups were 11.20 ± 2.26 μg/mL and 9.79 ± 1.98 μg/mL, respectively (p < 0.05) (Fig 5C and 5D and Table 3). The gene discussed is GPX3; the disease is non-small cell lung carcinoma.
