阿伐他汀激活wnt/β-catenin信號通路促進骨質(zhì)疏松模型大鼠移植物的骨整合(英文)
發(fā)布時間:2024-12-27 01:46
背景:最近研究報道阿伐他汀可減少骨流失和骨折,但其對移植物骨整合的影響尚未可知。目的:探討阿伐他汀在骨質(zhì)疏松癥動物模型中對移植性骨整合的作用及相關(guān)作用機制。方法:將48只SD大鼠隨機分為假手術(shù)組,卵巢切除組,10,20 mg/(kg·d)阿伐他汀治療組。除假手術(shù)組外,其他各組均進行卵巢切除手術(shù)和骨移植。干預(yù)12周后檢測各組大鼠椎骨骨密度,移植物骨整合率及移植物抗拔強度。另外,用阿伐他汀處理大鼠的成骨細胞,酶聯(lián)免疫法檢測細胞中骨形成及骨吸收生物指標的表達情況,RT-PCR檢測wnt信號通路相關(guān)基因的mRNA表達水平。結(jié)果與結(jié)論:20 mg/(kg·d)阿伐他汀治療組大鼠的骨密度、骨整合率及移植物抗拔強度均明顯高于卵巢切除組(P<0.05)。用阿伐他汀處理的大鼠成骨細胞中堿性磷酸酶、骨鈣蛋白及骨保護素表達水平明顯升高(P<0.05),破骨細胞分化因子核因子κB受體活化因子配體的表達顯著降低(P<0.05)。阿伐他汀治療組明顯提高低密度脂蛋白相關(guān)蛋白5和連環(huán)蛋白的mRNA表達(P<0.05),抑制Wnt信號通路抑制劑DKK1和骨硬化蛋白Sost的表達(P<0.0...
