ABSTRACT
Objective:
To observe the expression of VEGF-C protein in human gastric cancer cells SGC-7901 those transfected by pCI-neo-antisense VEGF-C and investigate whether antisense VEGF-C gene could inhibit the growth of human gastric carcinoma cell line in vitro.Methods:
By the liposome infection protocol,We transfected two different plasmids including pCI-neo and pCI-neo antisense VEGF-C into human gastric cancer cell line SGC-7901 cultured in vitro.Then those resistant clones were selected by G418 and expanded in DMEM culture medium.Then we used Immunohistochemical method and Western-blot to detect target genes and its expression.The cell viability was detected by MTT assay.We took the untransfected group as the control.Results:
The immunohistochemical method and Western-blot showed that there were no expression of VEGF-C mRNA and its protein in the group that transfected by plasmid pCI-neo antisense VEGF-C.MTT assay showed that the group of transfected with antisense VEGF-C had a lower cell viability than other groups(P
