ABSTRACT
To investigate whether there is mutation in DC-SIGN promoter region in patients with chronic hepatitis B (CHB) and healthy persons previously infected with hepatitis B virus (HBV) and to explore the relationship between the mutation in dendritic cell-specific intercellular adhension molecule-3-grabbing nonintegrin (DC-SIGN) promoter region and HBV.Methods The studied population was composed of two cohorts47 CHB patients and 20 healthy persons previously infected with HBV.The mutation in DC-SIGN promoter region was detected with PCR,single-stranded conformational polymorphism and heteroduplex analysis,cloning,sequencing and aligning the published DC-SIGN promoter sequence.Results The characteristic mutation within DCSIGN promoter region in HBV infected individuals was observed.In the DC-SIGN promoter region,4 hot spot mutations located in positions - 139,- 142,- 222,and - 336 were observed in the CHB patients,but only 1 spot mutation located in position - 139 was observed in the healthy persons previously infected with HBV.The -336C which was absent in the healthy persons previously infected with HBV was shown in 11 CHB patients (23.40%).The - 139T was far more frequent in the healthy persons previously infected with HBV ( 100% ) than in the CHB patients (34.04%).Conclusion In the DC-SIGN promoter region,-336C may be a genetic risk factor for developing CHB,but -139T may be associated with protection against HBV.
