TGF-β1rs1800469基因多态性与HBV感染及肝癌家族聚集的相关性

Association between TGF-β1 rs1800469 polymorphism and susceptibility to hepatocellular carcinoma in Chinese Guangxi populations: A meta-analysis

AIM

To systematically evaluate the association between the transforming growth factor-β1 (TGF-β1) rs1800469 (C-509T) polymorphism and susceptibility to hepatocellular carcinoma in Chinese Guangxi populations.

METHODS

An electronic search of PubMed, EMBASE, CNKI, Weipu, and Wanfang database for relevant articles was conducted. The difference of TGF-β1 rs1800469 (C-509T) genotypes (T vs C, TT vs CC, TC vs CC, TT+TC vs CC, and TT vs TC+CC) between cases and controls was analyzed through meta-analysis.

RESULTS

A total of six studies involving 2202 cases and 2382 controls were finally included. There was evidence of association between TGF-β1 rs1800469 (C-509T) polymorphism and the risk of hepatocellular carcinoma in Guangxi populations (TC vs CC: OR = 1.18; 95%CI: 1.03-1.36, P = 0.02).

CONCLUSION

Our meta-analysis suggested that the TGF-β1 rs1800469 (C-509T) polymorphism is more likely to be associated with hepatocellular carcinoma risk in Guangxi populations, and TGF-β1 rs1800469 (C-509T) TC genotype increases the susceptibility to hepatocellular carcinoma in Guangxi populations.

Association between HLA-DRB1* 09/12/15 alleles and HBV-related hepatic diseases

AIM: To assess the relationship between leukocyte antigen (HLA)-DRB1 alleles and HBV-related hepatic diseases in Guangxi.

METHODS: Polymerase chain reaction-sequence specific primer (PCR-SSP) method was used to determine the frequencies of HLA-DRB1* 09/12/15 alleles in 64 patients with asymptomatic chronic hepatitis B (ASC), 80 patients with chronic hepatitis B (CHB), 65 patients with liver cirrhosis (LC), 56 patients with hepatocellular carcinoma (HCC), and 75 healthy controls from Guangxi Province, China.

RESULTS: The frequency of the HLA-DRB1* 15 allele differed significantly among the five groups of subjects (P < 0.05), while the frequencies of the other alleles showed no significant differences (all P > 0.05). The frequency of the HLA-DRB1* 15 allele in patients with LC (10.8%) was significantly lower than those in patients with NC (34.7%), ASC (39.1%), HCC (33.9%), or CHB (33.8%) (all P < 0.01), but showed no significant difference between patients in the other four groups (all P > 0.05).

CONCLUSION: The lack of the expression of HLA-DRB1*15 gene might associate with a higher risk for the development of LC in patients with HBV infection.
