Abstract

The p73 gene is a structural and functional homolog of the p53 gene, which has a crucial role in mediating cell cycle arrest and apoptosis. Numerous previous studies have investigated the polymorphism of p73 G4C14‑to‑A4T14 at exon 2, as it was suggested to affect gene expression and result in functional significance. However, the correlation of this polymorphism with clinicopathological variables of patients with non‑small cell lung cancer (NSCLC) remains to be elucidated. The aim of the present study was to examine the association between the gene polymorphism of p73 G4C14‑to‑A4T14 and the risk of developing NSCLC. The single‑nucleotide polymorphisms of p73 G4C14‑to‑A4T14 were genotyped using polymerase chain reaction with confronting two‑pair primers and direct DNA sequencing in 186 NSCLC patients and 196 cancer‑free controls. χ2‑tests and logistic regression analysis were used to analyze the experimental data, including the determination of odds ratio (OR), 95% confidence intervals (95% CIs) and P‑values. The results demonstrated that the AT/AT genotype was associated with a significantly decreased risk of NSCLC (P=0.010; OR=0.370; 95% CI=0.170‑0.806) compared with the GC allele genotypes including GC/GC and GC/AT. In addition, carriers of the AT allele exhibited a significantly reduced risk of NSCLC (P=0.038; OR=0.713; 95% CI=0.517‑0.983) compared with non‑carriers. In conclusion, these results indicated that the p73 G4C14‑to‑A4T14 polymorphism was a potential marker of NSCLC genetic susceptibility. However, further studies with a larger population are required in order to confirm these results.
