Abstract:
OBJECTIVETo identify the siRNA interference ability for the replication of HBV.
METHODSBased on the sequence of HBV in HepG2 2.2.15 cells in GenBank, one sequence targeting the C antigen of HBV was cloned into the RNA polymerase III based expression vector pSuper. This recombinant was electroporated into HepG2 2.2.15 cells and the expression of HBsAg and HBeAg was assayed using ELISA.
RESULTSThe construction of the recombinant expression vector pSuper-C and its control vector pSuper was successfully confirmed by the results of enzyme digestion, electrophoresis and sequencing. However, there was no difference between the expression of HBsAg and HBeAg in the supernatant of HepG2 2.2.15 cell culture in the experimental and control groups.
CONCLUSIONSThe constructed pSuper-C did not show an interfering effect on the replication of HBV in HepG2 2.2.15 cells. In order to display this effect, further study is needed
