ATOX1 and non-small cell lung carcinoma: Differential overexpression of ATOX1 was detected in all of the NSCLC tissue samples (n=5) tested in this study (Fig. 1A and Table I), when compared with the low level of expression of ATOX1 in the non-malignant lung tissue (n=3) of the control group (Fig. 1B and Table I).
