摘要:
目的 研究补肾活血中药血清对加压纯化培养视网膜神经节细胞(retinal ganglion cells,RGCs)凋亡模型PI3K/Akt信号转导通路主要成员PI3K及Akt表达的影响,探索补肾活血法保护RGCs的机制。方法制备补肾活血中药含药血清,体外纯化SD大鼠RGCs,采取开放式压力控制培养系统建立体外加压培养RGCs凋亡模型,以50 g·L-1、100 g·L-1、200 g·L-1血清浓度梯度补肾活血中药血清分别处理。将RGCs分为5组,分别为正常培养组(N组)、对照组(C组)、50 g·L-1补肾活血中药血清组(50 g·L-1BSHX组)、100 g·L-1补肾活血中药血清组(100 g·L-1BSHX组)、200 g·L-1补肾活血中药血清组(200 g·L-1BSHX组),Annexin V-FITC/PI双染检测细胞凋亡率,实时荧光定量PCR(qRT-PCR)检测补肾活血中药血清对RGCs PI3K及Akt mRNA表达水平的影响,Western blot检测各组PI3K、Akt蛋白表达量。结果 Q-PCR检测各组mRNA结果:C组(0.04±0.01)与N组(1.00±0.04)相比,RGCs中PI3K、Akt的mRNA表达水平下降,差异均有统计学意义(均为P<0.05),而50 g·L-1、100 g·L-1、200 g·L-1BSHX组(0.18±0.01、0.21±0.02,0.22±0.01、0.36±0.01,0.84±0.10、1.07±0.17)与C组相比,PI3K、Akt mRNA含量逐渐升高,差异均有统计学意义(均为P<0.05)。Western blot检测各组蛋白表达,C组与N组相比,细胞PI3K、Akt的蛋白表达水平下降,差异有统计学意义(P<0.05),而50 g·L-1、100 g·L-1、200 g·L-1BSHX组与C组相比,PI3K、Akt蛋白表达量逐渐升高,差异均有统计学意义(均为P<0.05)。结论 补肾活血中药血清抑制加压诱导的RGCs凋亡,其机制可能与激活PI3K/Akt信号转导通路有关。
Abstract:
Objective To investigate the influence of bushenhuoxue drug-containing serum on PI3K and Akt signaling pathway in purified retinal ganglion cell (RGCs) in vitro of Sprague-Dawley (SD) rats,and to explore the protective mechanisms of bushenhuoxue recipe on RGCs.Methods At first,bushenhuoxue drug-containing serum was prepared,and the RGCs of SD rats were purified;after the apoptotic model of pressurized and purified RGCs was established successfully in vitro using open pressure control system,RGCs were dealt with 50 g·L-1,100 g·L-1,200 g·L-1 concentration gradient of bushenhuoxue drug-containing serum.Then the subjected cells were divided into normal culture group (N group),control group (C group),50 g·L-1 bushenhuoxue group (50 g·L-1 BSHX group),100 g·L-1 bushenhuoxue group (100 g·L-1 BSHX group),200 g·L-1 bushenhuoxue group (200 g·L-1 BSHX group).Finally,cell apoptotic rate was detected by Annexin V-FITC/PI staining,while real-time quantitative PCR (qRT-PCR) and Western blot were used to detect the mRNA and protein expression of PI3K and Akt in each group respectively.Results The results of qRT-PCR detection showed that PI3K,Akt mRNA expression level in C group (0.04±0.01) was decreased compared with N group(1.00±0.04),and the difference was statistically significant (all P<0.05),while PI3K,Akt mRNA levels in 50 g·L-1,100 g·L-1 and 200 g·L-1 BXHX group (0.18±0.01,0.21±0.02,0.22±0.01,0.36±0.01,0.84±0.10,1.07±0.17) were increased compared with the C group,and the difference was statistically significant (all P<0.05).The Western blot results of each group showed that PI3K,Akt protein expression level in C group was decreased compared with N group,with statistical difference (all P<0.05),while PI3K,Akt protein expression levels in 50 g·L-1,100 g·L-1 and 200 g·L-1 BSHX group were increased compared with C group,with statistical difference (all P<0.05).Conclusion Bushenhuoxue drug-containing serum may inhibit the RGCs apoptosis induced by pressure,which may be related to the activation of PI3K/Akt signal transduction pathway.
