Lysyl oxidase (LOX) is a copper-dependent amine oxidase that plays important roles in the homeostasis of tumors. The aim of this study was to investigate the association between LOX polymorphisms and cervical cancer, and the effect of these polymorphisms on gene expression. We evaluated two polymorphisms of LOX, rs1800449G/A (G473A) and rs2278226C/G, in 262 cervical cancer cases and 298 healthy controls in the Chinese population. Results showed that the prevalence of rs1800449AA genotype was significantly increased in cases than in controls (p=0.004). Individuals who carried the rs1800449A allele had a 1.56-fold increased risk for cervical cancer than those with the rs1800449G allele (p=0.003). The rs2278226CG genotype also revealed a significantly higher proportion in cases (20.6%) than in controls (7.7%, p<0.001). Interestingly, when analyzing these two polymorphisms with the serum level of LOX, we identified that cervical cancer patients carrying the rs2278226CG genotype had a significantly elevated level of LOX than those with rs2278226CC wild type, whereas the same phenomenon was not observed in controls. The rs1800449 polymorphism did not affect the LOX serum level in either controls or patients. These results suggest that the polymorphisms in the LOX gene may be involved in the development of cervical cancer through various mechanisms.
