Relationship between HLA-DQB1 allele polymorphism with HPV16 infection and cervical cancer susceptibility in Guangxi Zhuang women / 中国免疫学杂志

ABSTRACT

Objective:To study the relationship of Guangxi Zhuang women being infected by HPV16 and suffering from cervical cancer with HLA-DQB1 allele polymorphism.Provide clues for seeking hereditary susceptibility gene or resistant gene of cervical cancer of Guangxi Zhuang women.Methods:Chose the cervical cancer diagnosed female patients and health women 171 cases respectively aged between 25 and 45 of Guangxi as subject investigated(people in the two groups were paired by age ±3 years).Took their samples to extract HPV DNA and human genome DNA.Then detected HLA-DQB1 alleles and HPV genetype applying PCR-SSP and molecular diversion hybrid technology.Finally the data were statistically analyzed.Results:(1)The total infection rate of HPV in 171 cases of cervical cancer patient was 91.22%,in which the high-risk virus accounted for 90.76%,HPV16 was the main pathogenic subtypes(43.58%).(2)The allele carrying rate of HLA-DQB1*04 in the cervical cancer group was higher than the health control group with statistically significant difference(P0.05).(3)The occurrence frequency of HLA-DQB1*04 alleles in HPV16 positive cervical cancer patients was significantly higher than HPV16 negative patients with statistically significant difference(P<0.05).Conclusion:HLA-DQB1*04 alleles are probably the susceptibility genes of cervical cancer of Guangxi Zhuang women;HLA-DQB1*06/09 alleles are probably the protective genes of cervical cancer of Guangxi zhuang women;HLA-DQB1*02/05/07/08 alleles seem irrelevant to hereditary susceptibility of cervical cancer of Guangxi Zhuang women.And Guangxi Zhuang women carried HLA-DQB1*04 alleles are more likely to infect HPV16 that increase the risk of cervical cancer.
