摘要:
METHODS: Human gastric mucosal epithelial cell (GES-1) was cultured and divided into 4 groups: a control, a DA, a PNS+DA and a LY294002+PNS+DA组。 GES-1 AP通过流式细胞仪检测到Optosis,使用Transwell,前列腺素E2(PGE2),6-酮 - 前蛋白蛋白F1α(6-酮-PGF1α)和血管内皮生长因子(VEGF)在enzyme链接的免疫器辅助(Elis)中测量的(6-酮-PGF1α)和血管内皮生长因子(VEGF)检测到细胞渗透率。 3-kinase (PI3K), phosphorylated-PI3K (p-PI3K), Akt, phosphorylated-Akt (p-Akt), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), glycogen synthase kinase-3β (GSK-3β) and Ras homolog gene family member A (RhoA) were measured by Western-blot。
结果: dA诱导的GES-1中的凋亡和过度渗透性,降低了PGE2,6-酮PGF1α和VEVGF(p <0.05)的上清液水平。 PNS的添加降低了由DA引起的GES-1的凋亡,恢复了PGE2、6-酮PGF1α和VEGF的浓度(P <0.05)。此外,PNS减弱了由DA,上调的P-PI3K/P-AKT诱导的COX-1和COX-2表达的改变,DOWN调节的RhoA和GSK-3β。 LY294002 mitigated the effects of PNS on cell apoptosis, cell permeability, VEGF concentration, and expression of RhoA and GSK-3β significantly.
CONCLUSIONS: PNS attenuates the suppression on COX/PG pathway from DA, alleviates DA-induced通过PI3K/AKT/VEGF-GSK-3β-RHOA网络途径的GES-1凋亡和屏障功能障碍。
