OBJECTIVE: To investigate the association between HPV infection and HLA-DQB1 alleles polymorphism in the cervical carcinogenesis in Uyghur women in southern Xinjiang. METHODS: Twenty-one subtypes of HPV and the 5 alleles of HLA-DQB1 were detected from cervical tissues of 190 cervical cancer cases and 190 normal subjects by flow-through hybridization and gene chip (HybriMax) assay and polymerase chain reaction sequence-specific oligonucleotide technique (PCR-SSO). RESULTS: (1) The positive rate of HPV in cervical cancer and control groups were 70.0% and 8.9%, respectively. HPV16 was the most common type in HPV positive cervical cancer patients with a rate of 64.7%, followed by HPV18 (2.6%), HPV68 (2.1%), HPV45 (1.6%), HPV58 (1.6%), HPV39 (1.6%), HPV31 (1.1%), HPV56 (1.1%), HPV59 (0.5%), HPV53 (0.5%) and HPV6 (0.5%), respectively. The positive rates of HPV and HPV16 in the cervical cancer group were significantly higher than that in the control group. (2) The frequency of HLA-DQB1*03 was significantly lower than that in the control group (OR = 0.683, 95%CI = 0.505 - 0.923). The frequency of other HLA alleles had no significant differences between the cervical cancer group and the control group. (3) In the cervical cancer group, the frequency of HLA-DQB1*06 in both HPV positive and HPV16 positive cases were significantly higher than that in both the HPV and HPV16 negative cases. CONCLUSION: HPV16 is the most common type in both the cervical cancer and control groups. It appears that HLA-DQB1*03 may be a protective gene in the cervical carcinogenesis in southern Xinjiang Uyghur women, and the HLA-DQB1*06 is a susceptibility gene to HPV/HPV16 infection in Uyghur women. The study of HLA alleles in the cervical carcinogenesis in Uyghur women may play an important role in the intervention research of cervical cancer.
