Figure 3.

Gene expression levels in all NSCLC tissues and paired non-cancerous tissues. Relative expression is presented as 2^-ΔCT ± S.E. The expression of 18S rRNA acts as reference gene. There is a significant increase in gene expression for GABR_A3 (*P = 0.030, Figure 3A), GABR_E (*P = 0.036, Figure 3B) and GABBR₂ (**P = 0.005, Figure 3C) in NSCLC tissues, with no difference in expression for GABR_B3 (P = 0.742, Figure 3D), GABR_P (P = 0.288, Figure 3E) and GABBR₁ (P = 0.746, Figure 3F). * P < 0.05, ** P < 0.01.
