title: Construction of antisense transforming growth factor beta 1 gene and its effect on the proliferation by expression in osteosarcoma cells.
abstract: To construct the antisense transforming growth factor beta 1 (TGF beta 1) gene and investigate the effect of TGF beta 1 autocrine loop blockage on the proliferation of osteosarcoma cells. TGF beta 1 cDNA was cloned by RT-PCR from human osteosarcoma cells (MG-63) and inserted into pcDNA3 to construct an antisense expression vector, which was dubbed pcDNA3-TGF beta 1(-). MTT was used to detect the proliferation of osteosarcoma cells transfected by antisense TGF beta 1 gene. Our results showed that the proliferation of the transfected osteosarcoma cells was suppressed markedly. It is concluded that TGF beta 1 autocrine loop blockage in osteosarcoma cells could inhibit cell proliferation, which might be helpful for gene therapy of osteosarcoma.
