ABSTRACT
Objective:
To elucidate the relationship between HLA-DQB1 allele polymorphism as well as the expression level of Th1/Th2 cytokines with familial clustering of hepatocellular carcinoma ( HCC) to provide some evidence for the seeking susceptibility gene or resistant gene of HCC in Guangxi yao,China.Methods:
With the same sexuality,age ±5 year,40 members whose families have had two or more HCC patients( high-occurrence families) were selected as the case group,and 40 members whose families have no any cancer patient were selected as the controls.Peripheral blood samples were collected to extract DNA,PCR-SSP was used to detect HLA-DQB1 alleles and ELISA was used to detect IL-2,IL-4 and IL-10.Results:
(1) The gene frequency of the HLA-DQB1*02/09 alleles in the case group was higher than that in the controls(P0.05 ).( 2 ) The gene frequency of alleles HLA-DQB1 in HBsAg positive group and HBsAg negative group were never significant difference (P>0.05).(3)The expression levels of IL-4,IL-10 in the case group was higher than that in the control ( P<0.05 ).( 4 ) The expression level of IL-10 in the positive group of the HLA-DQB1*02 allele was higher than that in the negative group of the HLA-DQB1*02 allele ( P<0.05 ).( 5 ) The expression level of IL-4 in the positive group of the HLA-DQB1*09 allele was higher than that in the negative group of the HLA-DQB1*09 allele( P<0.05) .Con-clusion(1) HLA-DQB1*02/09 seem to be susceptibility genes of hepatocellular carcinoma in high HCC incidence areas of Guangxi yao.(2) There may be not significant correlation bewteen HLA-DQB1 alleles and the susceptibility of HBV infection in high HCC incidence areas of Guangxi yao.( 3 ) The imbalance of IL-4, IL-10 might be associated with familial clustering of hepatocellular carcinoma in Guangxi yao.(4)The imbalance of IL-10 might be due to the carrying of HLA-DQB1*02;the imbalance of IL-4 might be due to the carrying of HLA-DQB1*09.Through the same approaches,these might lead to the phenomenon of familial aggregation of HCC in Guangxiyao.
