摘要
To construct the antisense transforming growth factorβ1 (TGFβ1) gene and investigate the effect of TGFβ1 autocrine loop blockage on the proliferation of osteosarcoma cells. TGFβ1 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-TGFβ1(-). MTT was used to detect the proliferation of osteosarcoma cells transfected by antisense TGFβl gene. Our results showed that the proliferation of the transfected osteosarcoma cells was suppressed markedly. It is concluded that TGFβ1 autocrine loop blockage in osteosarcoma cells could inhibit cell proliferation, which might be helpful for gene therapy of osteosarcoma.
