title: [Effect of matrine injections on invasion and metastasis of gastric carcinoma SGC-7901 cells in vitro].
abstract: OBJECTIVE
  To investigate the effect of matrine injections on invasion and metastasis of gastric carcinoma SGC-7901 cells in vitro.
  
  
  METHODS
  MTT assay was used to examine the effect of matrine injections on proliferation of SGC-7901 cells after 24, 48, 72, 96 hours treatment; Transwell chamber assay was performed to determine the effect of matrine injection on invasion and migratory capacity of the cells; Effect on adhesion potential of SGC-7901 cells was tested by cell matrigel adhesion assay.
  
  
  RESULTS
  Matrine injec-tions could inhibit the proliferation of SGC-7901 cells, with obvious dose-dependent and time-dependent effects. Matrine injections sig-nificantly inhibited adhesion, invasion and migration capacity of SGC-7901 cells in vitro. The inhibitory rate of them after treatment with 1.5 mg/ml matrine injections for 24 h were (45.32 +/- 3.10)%, (32.66 +/- 2.82)%, (38.35 +/- 3.41)% respectively. After treat-ment of matrine injections (1.5 mg/ml)for 24 h, the expression level of CD44(V6) in SGC-7901 cells was decreased compared with the untreated group.
  
  
  CONCLUSIONS
  Matrine injections can inhibit the migration, invasion and adhesion capacity of SGC-7901 cells in vitro. The inhibition effect may be related to down-regulating the expression of CD44(V6) protein.
