Objective:To study the effect of hypoxia on the invasion
metastasis
and angiogenesis of gastric cancer in vitro. Methods: MTT was used to study the effects of viability durng hypoxia on SGC-7901
The Boyden Chamber membrane invasion culture system was used to study invasion
metastasis
and angiogenesis. Immunocy tochemical staining was used to observe the change of TGF-β1. Resuts: In the membrane invasion culture system
the numbers of invading and migrating SGC-7901 cells were significantly higher in hypoxia group than in the control group (P<0.05)
and the numbers and length of tubes were significantly higher in hypoxia group too(P<0.05). The adhesion rate and TGF-β1 expression were regulater in hypoxia group (P<0.05). Conclusion:Hypoxia can inhibit the migration
invasion
and angiogenesis of SGC- 7901 gastric cancer cells in vitro. The mechanism may be regulation of TGF-β1 expression.
