文题释义:
PERK/Bip信号通路:PERK/Bip信号通路在骨关节炎的病理过程中具有重要调节作用,在非应激状态时,蛋白激酶PERK与分子伴侣Bip结合。应激反应发生时,Bip结合未折叠蛋白,使PERK胞浆区的蛋白激酶活化,磷酸化eIF2α,下调细胞内大部分蛋白质的合成,导致异常蛋白产生减少,并高表达Bip等分子伴侣,从而减轻内质网应激反应。
独活寄生汤:由独活、桑寄生、牛膝、杜仲、秦艽、防风、肉桂、细辛、当归、川芎、干地黄、芍药、人参、茯苓、甘草组成,具有补肝肾、益气血、祛风湿、止痹痛之效,可有效缓解膝骨关节炎患者临床症状,具有疗效可靠、不良反应小、经济等优点。
摘要
背景:
前期研究表明独活寄生汤可有效抑制软骨细胞凋亡,但其具体机制尚不明确。
目的:观察独活寄生汤对膝骨关节炎大鼠软骨PERK/Bip信号通路关键调节因子PERK、Bip、eIF-2α、ATF-4、GADD153、Caspase-9、Caspase-3的影响,探讨独活寄生汤防治骨关节炎的作用机制。
方法:80只SD大鼠适应性喂养1周后,随机分为正常组(20只)和造模组(60只)。造模组应用膝关节注射木瓜蛋白酶法制备膝骨关节炎模型。造模成功后随机分为3组,即模型组(n=20)、治疗组(n=20)和阳性对照组(n=20)。正常组和模型组给予生理盐水;治疗组给予独活寄生汤,按照9.3 g/(kg•d)的药量进行灌胃;阳性对照组给予盐酸氨基葡萄糖胶囊0.15 g/(kg•d)。2周为1个疗程,共4个疗程。分别于2,4个疗程后切取右侧胫骨平台,免疫组化法和RT-PCR法检测PERK、Bip、eIF-2α、ATF-4、GADD153、Caspase-9、Caspase-3蛋白和mRNA表达情况。
结果与结论:①RT-PCR结果显示,独活寄生汤和盐酸氨基葡萄糖均能抑制PERK、Bip、eIF-2α、ATF-4、GADD153、Caspase-9、Caspase-3 mRNA表达(P < 0.05或0.01),干预时间越长,效果越明显,但2组间无显著差异(P > 0.05);②免疫组化结果与RT-PCR结果趋势一致,即独活寄生汤和盐酸氨基葡萄糖均能抑制PERK、Bip、eIF-2α、ATF-4、GADD153、Caspase-9、Caspase-3蛋白表达(P < 0.05或0.01),干预时间越长,效果越明显,但2组间无显著性差异(P > 0.05);③结果提示,独活寄生汤可能是通过调控PERK/Bip信号通路,进而抑制因内质网应激反应引起的软骨细胞凋亡。

Abstract:

BACKGROUND: Preliminary study has shown that Duhuo Jisheng Decoction (DHJSD) is an effective prescription for osteoarthritis. But the underling mechanism remains unclear.
OBJECTIVE: To observe the effect of DHJSD on the key regulating factors PERK, Bip, eIF-2α, ATF-4, GADD153, Caspase-9 and Caspase-3 in PERK/Bip signaling pathway in cartilage of rats with knee osteoarthritis, so as to explore its treatment mechanism.
METHODS: After 1 week of acclimation, 80 Sprague-Dawley rats were randomly divided into normal group (n=20) and model rats (n=60). Osteoarthritis was induced by injecting 0.2 mL of 4% papain solution in both knees. The rat models were randomly divided into three groups, including model, treatment and positive control groups (n=20 per group). The normal and model groups received treatment of normal saline. The treatment and positive control groups were given DHJSD (9.3 g/(kg•d)) and glucosamine hydrochloride capsule 0.15 g/(kg•d) via gavage, respectively, for four courses (two weeks a course). After every two courses, the animals were sacrificed and the right tibial plateau was obtained. The mRNA and protein levels of PERK, Bip, eIF-2α, ATF-4, GADD153, Caspase-9 and Caspase-3 were measured by RT-PCR and immunohistochemistry, respectively.
RESULTS AND CONCLUSION: RT-PCR results showed that DHJSD and glucosamine hydrochloride capsule could time-dependently inhibit the mRNA expression of PERK, Bip, eIF-2α, ATF-4, GADD153, Caspase-9 and Caspase-3 (P < 0.05 or P < 0.01). There was no significant difference between treatment and positive control groups (P > 0.05). Immunohistochemistry results found that DHJSD and glucosamine hydrochloride capsule could time-dependently inhibit the protein expression of PERK, Bip, eIF-2α, ATF-4, GADD153, Caspase-9 and Caspase-3 (P < 0.05 or P < 0.01). There was no significant difference between treatment and positive control groups (P > 0.05). These results suggest that DHJSD can inhibit the apoptosis of chondrocytes caused by endoplasmic reticulum stress through regulating the PERK/Bip signaling pathway.
