Abstract:
Objective To investigate the effect of endocrine gland-derived vascular endothelial growth factor(EG-VEGF) on the proliferation and apoptosis of pancreatic cancer cells and on the regulation of PI3K/AKT signaling pathway.Methords The expression of EG-VEGF and its receptor-VEGFR-2 in pancreatic cancer tissues and adjacent normal tissues was detected by PCR.The effect of EG-VEGF on proliferation of human pancreatic cancer cells was detected by MTT assay.The effect of EG-VEGF on the apoptosis of human pancreatic cancer cells was detected by flow cytometry.Western lot was used to detect the changes of related proteins expression in PI3K/AKT signaling pathway after EG-VEGF treatment.Results The expression (3.08±0.30,2.17±0.16 respectively) of EG-VEGF and VEGFR-2 in pancreatic cancer tissues was significantly higher than those (1.55±0.73,0.54±0.34 respectively) in adjacent tissues (both P< 0.05).MTT and flow cytometry data showed that EG-VEGF could promote the proliferation of pancreatic cancer cells and inhibit cell apoptosis.Western blot showed that EG-VEGF promoted AKT phosphorylation and activated PI3K/AKT signaling pathway.Conclusion EG-VEGF is highly expressed in pancreatic cancer tissue,and can activate PI3K/AKT signaling pathway to promote cell proliferation and inhibit cell apoptosis.
