The GPx3 level of the control group was also significantly different from that of the NSCLC group (p < 0.01); the mean GPx3 levels of the control and NSCLC groups were 13.79 ± 5.25 μg/mL and 9.01 ± 4.27 μg/mL, respectively (Fig 6B and Table 3). Here, GPX3 is linked to non-small cell lung carcinoma.
