摘要:

目的:探讨清络饮(Qing-Luo-Yin,QLY)经HIF-1α/VEGF通路治疗佐剂诱导关节炎(adjuvant-induced arthritis,AIA)大鼠模型异常血管新生的基本机制。方法:SD大鼠诱导建立AIA模型后采用QLY浸膏连续灌胃治疗,观察关节病理变化;ELISA法检测血浆中HIF-1α、VEGF、PDGF、TGF-β1浓度;生化法检测血浆中MDA和SOD等水平。体外实验中,采用MTT法、细胞划痕实验和成管实验评价QLY的抗血管新生能力,并同步检测相关蛋白表达水平。结果:与对照组比较,AIA大鼠关节滑膜增生和血管新生明显,伴有HIF-1ɑ、VEGF、PDGF、TGF-β1水平上升,而MDA/SOD比例降低;QLY治疗后上述异常均得以缓解。体外QLY刺激HUVEC细胞,抑制了后者增殖、愈伤和成管能力,p-MEK/MEK、p-ERK/ERK及HIF-1α表达显著降低。结论:清络饮可能通过调控 HIF-1α/VEGF信号通路抑制HUVEC细胞增殖、迁移和血管新生,减轻AIA组大鼠的氧化应激反应和血管翳形成。

Abstract:

AIM: To investigate the involvement of HIF-1α/VEGF regulation in its anti-angiogenesis effects using adjuvant-induced arthritis (AIA) rats. METHODS: AIA rats were orally treated by QLY extract for 24 days. After sacrifice, the joints were subjected to histological examination, while the blood was used in ELISA or biochemical tests. In addition, HUVEC cells were treated by QLY in vitro. MTT, wound-healing and tube-formation experiments were then  performed. Expression of some relevant proteins in cells were investigated.RESULTS: Compared to the healthy controls, obvious synovial invasion and angiogenesis occurred in AIA rats. Blood levels of HIF-1ɑ, VEGF, PDGF, and TGF-β1 were increased, while the ratio of MDA/SOD was decreased a lot. After QLY treatment, all these abnormalities were attenuated. In vitro experiments, QLY showed notable potentials in inhibiting proliferation, migration and tube-constructing abilities of HUVEC cells. Furthermore, it suppressed the expression of p-MEK/MEK and p-ERK/ERK. CONCLUSION: QLY can reduce the pathological functions of vascular endothelial cells by inhibiting HIF-1α/VEGF, and it consequently eased AIA-related abnormal angiogenesis in AIA rats' joints.
