Abstract:
Objective To investigate the effect of anti-sense osteopontin(ANOPN)on proliferation and metastasis of esophagus cancer cells.Methods An OPN gene recombinant expression vector plasmid was constructed by RT-PCR from human umbilical vein endothelial cell gene and cloned into a mammalian expression vector pcDNA3.1(+).PcDNA3.1-ANOPN was introduced by LipofectinTM.Positive cell clones(ECA-ANOPN),vector-transfected cells ECA-vect and blank cell ECA were used as three groups.RT-PCR and immunocytochemistry assay were used to investigate the expressions of OPN mRNA and protein.The metastasis characteristics of cells were studied by Transwell method.Results The vector was constructed successfully,the sequencing result was identical with that reported in GenBank.Compared with vector-transfected cells(ECA-vect cells) and ECA cells,the growth rate of ECA-ANOPN cells was significantly slowed(P
