Expression Levels of Some Antioxidant and Epidermal Growth Factor Receptor Genes in Patients with Early-Stage Non-Small Cell Lung Cancer

Table 2

Distribution of gene transcript levels (medians and interquartile (25th–75th) ranges of values in arbitrary units, a.u) in cancerous and unaffected tissues. Results of paired sample analysis (Wilcoxon’s test) are shown (𝑃).

Gene	Cancerous tissue,	Unaffected tissue,	𝑃
transcripts	a.u.	a.u.
HO-1	0.10 (0.07–0.15)	0.16 (0.13–0.22)	.031
SOD-1	0.13 (0.09–0.15)	0.18 (0.14–0.19)	.006
SOD-2	0.17 (0.09–0.23)	0.26 (0.18–0.36)	.001
EGFR	0.07 (0.04–0.09)	0.05 (0.03–0.07)	.258
HER-2	0.23 (0.09–0.37)	0.23 (0.16–0.35)	.228
