【摘要】 目的:观察丙泊酚对人胃癌细胞SGC-7901侵袭和迁移能力的影响。方法:用不同浓度(1、3、5和7 mg/L)的丙泊酚培养SGC-7901细胞24 h。MTT实验检测细胞活力,细胞侵袭实验和划痕愈合实验分别检测细胞侵袭和迁移能力;免疫细胞化学法和Western blot实验检测富半胱氨酸血管生成诱导因子61(CYR61)、CD44v6和基质金属蛋白酶7(MMP-7)3种蛋白的表达。结果:与对照组相比,5 mg/L丙泊酚对SGC-7901细胞的活力无明显影响,但显著抑制细胞的侵袭和迁移能力(P<0.05),并抑制CD44v6和MMP-7的表达(P<0.05)。结论:丙泊酚可抑制人胃癌细胞SGC-7901侵袭和迁移能力,抑制作用与CD44v6和MMP-7的表达降低相关。更多还原

【Abstract】 AIM: To investigate the effects of propofol on invasion and migration of gastric cancer cell line SGC-7901. METHODS: Cultured gastric cancer cell line SGC-7901 was randomly divided into 4 groups, and then diffe-rent concentrations(1, 3, 5 and 7 mg/L) of propofol were added and incubated for 24 h. The cell viability was measured by MTT assay. The invasion and migration abilities of the SGC-7901 cells were detected by Transwell assay and wound-healing assay. The expression of cysteine-rich angiogenic inducer 61(CYR61), CD44 v6 and matrix metalloproteinase-7(MMP-7) in the SGC-7901 cells were examined by immunocytochemistry and Western blot.RESULTS: Propofol at 5 mg/L does not affect the viability of SGC-7901 cells, whereas significantly suppresses the invasion and migration abilities, and down-regulates the expression of CD44 v6 and MMP-7(P<0.05). CONCLUSION: The decreased invasion and migration abilities of SGC-7901 cells were partly due to the inhibition of CD44 v6 and MMP-7 expression.更多还原
