| Research Abstract |
It has been reported that pigment epithelium-derived factor (PEDF), a protein previously shown to have neurotrophic activity is a potent inhibitor of angiogenesis, but the effect of PEDF in human cancers is not known. To investigate the effect of PEDF on the viability, growth invasion and metastasis of human pancreatic cancer. PEDF gene was transduced into the four human pancreatic cancer cell lines. The plasmid with simultaneous expression of PEDF and green fluorescence protein (GFP) was transduced into Panc-1, MiaPaCa-2, BxPC-3, and AsPC-1 by liposome-mediated transfection. After transfection, PEDF expression cells were selected by using fluorescence-activated cell sorting (FACS). The two human pancreatic cancer cell lines (Panc-1-PEDF and MiaPaCa-2-PEDF), which express PEDF gene, were established. For these two cell lines (Panc-1-PEDF and MiaPaCa-2-PEDF), the growth rates were compared with those of the parental cell lines. MiaPaCa-2-PEDF cell lines were inhibited on the growth. The growth curve indicated the difference on first, third, and fifth day. The difference was statistically significant. Morphological changes were not detected. These findings suggest that PEDF may have antitumof activity for the digestive system cancer.
