【Abstract】Objective To construct a recombinant adenoviral vector carrying antisense matrix metalloproteinase2 (MMP2) for use in the gene therapy to inhibit the invasiveness and migratory capacity of hepatocellular carcinoma (HCC) cell line HepG2 in vitro and in vivo models.
Methods Total RNA was extracted from HCC, and then a 500 bp fragment at the 5′ end of human MMP2 cDNA was synthesized by polymerase chain reaction (PCR) and was reversely inserted into the multiclone site (MCS) of the shuttle plasmid pAdTrack-CMV,with the resultant plasmid and the backbone plasmid pAdEasy-1,the homologous recombination took place in the E.coli BJ5183 and the recombinant adenoviral plasmid carrying the antisense MMP2 gene was constructed and generated. The adenoviruses(Ad-MMP2AS) were packaged and amplified in the HEK 293 cells.Then the viral titer was checked by GFP.
Results The recombinant adenovirus vector carrying antisense MMP2 was constructed successfully, the b green fluorescence was observed in HEK 293 cells under a fluorescence microscopy. The viral titer was 1×108/ml.
Conclusion The recombinant adenovirus Ad-MMP2AS constructed by us could introduce the antisense MMP2 into HepG2 effectively,which would provide experimental basis for reversing the overexpression of MMP2 in HCC and for inhibiting the invasiveness and migratory capacity of HepG2 in vitro and in vivo models.
