摘要:



文题释义:
NLRP3:由一个氨基末端Pyrin结构域、一个中央核苷酸结合和寡聚化结构域和一个C端富含亮氨酸重复序列结构域组成,与宿主对细菌、真菌和病毒感染的免疫防御至关重要,与炎症性疾病的发病机制有关。
积雪草苷:是一种从积雪草中提取的三萜类衍生物,具有广泛的药理活性,包括血管生成、抗炎、成骨分化和神经保护。近年来发现积雪草苷对细胞成骨分化具有积极影响,可能在骨质疏松治疗中发挥作用。

背景:研究表明,积雪草苷具有抗炎、抗氧化等多种药理功能,对细胞成骨分化具有积极影响,可能成为治疗骨质疏松的潜在药物。
目的:探讨积雪草苷对骨质疏松大鼠成骨分化的影响。
方法:①切除52只雌性SD大鼠双侧卵巢建立骨质疏松模型,同时切除10只雌性SD大鼠双侧卵巢附近等体积脂肪组织作为假手术组。造模8周后,将造模成功的50只大鼠随机分为5组干预:模型组(n=10)灌胃给予生理盐水,积雪草苷低剂量组(n=10)灌胃给予积雪草苷16 mg/(kg·d),积雪草苷高剂量组(n=10)灌胃给予积雪草苷32 mg/(kg·d),阳性药组(n=10)灌胃给予阿仑膦酸钠片7.35 mg/(kg·d),积雪草苷高剂量+激活剂组(n=10)同时灌胃给予32 mg/(kg·d)+NLRP3激活剂300 mg/(kg·d),1次/d,连续给药6周。给药结束后取材,检测血清中白细胞介素1β、白细胞介素18水平,Micro-CT扫描股骨远端,苏木精-伊红染色观察股骨组织学形态变化,免疫印迹检测股骨中三基序蛋白24、NLRP3、cleaved caspase-1蛋白表达。②将对数生长期的大鼠骨髓间充质干细胞分4组处理:空白组不进行任何处理,积雪草苷组加入20 µmol/L 积雪草苷处理48 h,积雪草苷+空载体组空载体质粒转染48 h后加入20 µmol/L 积雪草苷处理48 h,积雪草苷+NLRP3过表达组NLRP3过表达质粒转染48 h后加入20 µmol/L 积雪草苷处理48 h。成骨诱导分化7 d后,检测碱性磷酸酶活性与骨桥蛋白、骨钙蛋白、三基序蛋白24、NLRP3 mRNA表达。
结果与结论:①动物实验:积雪草苷低剂量组、积雪草苷高剂量组、阳性药组白细胞介素1β、白细胞介素18水平均低于模型组(P < 0.05),积雪草苷高剂量+激活剂组白细胞介素1β、白细胞介素18水平高于积雪草苷高剂量组(P < 0.05)。Micro-CT扫描与苏木精-伊红染色结果显示,相较于模型组,积雪草苷低剂量组、积雪草苷高剂量组、阳性药组股骨微结构与组织学形态明显改善,而NLRP3激活剂可部分抑制高剂量积雪草苷的作用效果。与模型组比较,积雪草苷低剂量组、积雪草苷高剂量组、阳性药组三基序蛋白24蛋白表达升高(P < 0.05),NLRP3、cleaved caspase-1蛋白表达降低(P < 0.05);积雪草苷高剂量+激活剂组三基序蛋白24蛋白表达低于积雪草苷高剂量组(P < 0.05),NLRP3、cleaved caspase-1蛋白高于积雪草苷高剂量组(P < 0.05)。②细胞实验:积雪草苷组碱性磷酸酶活性高于空白组、积雪草苷+NLRP3过表达组(P < 0.05)。RT-PCR检测显示,积雪草苷组骨桥蛋白、骨钙蛋白、三基序蛋白24 mRNA表达高于空白组、积雪草苷+NLRP3过表达组(P < 0.05),NLRP3 mRNA表达低于空白组、积雪草苷+NLRP3过表达组(P < 0.05)。③结果表明:积雪草苷可能通过上调三基序蛋白24表达、抑制NLRP3表达促进骨质疏松大鼠的成骨分化,延缓骨质疏松的发展。

Abstract: BACKGROUND: Studies have indicated that asiaticoside possesses multiple pharmacological functions, including anti-inflammatory and antioxidant properties, and exerts a positive effect on osteogenic differentiation. It may serve as a potential therapeutic agent for osteoporosis.
OBJECTIVE: To investigate the effects of asiaticoside on osteogenic differentiation in osteoporotic rats. 
METHODS: (1) Animal models of osteoporosis were established by removing both ovaries in 52 female Sprague-Dawley rats. Simultaneously, equivalent volumes of adipose tissue near the ovaries were removed bilaterally from 10 female Sprague-Dawley rats as the sham operation group. At 8 weeks after modeling, 50 model rats were randomly divided into five intervention groups: model group (n=10) was administered saline via oral gavage; low-dose asiaticoside group (n=10) was administered 16 mg/(kg·d) asiaticoside via oral gavage; high-dose asiaticoside group (n=10) was administered 32 mg/(kg·d) asiaticoside via oral gavage; positive control group (n=10) was subjected to oral administration of sodium alendronate tablets at 7.35 mg/(kg·d); and high-dose asiaticoside + activator group (n=10) received concurrent oral administration of 32 mg/(kg·d) asiaticoside + 300 mg/(kg·d) NLRP3 activator, once daily for 6 consecutive weeks. After drug administration, tissue samples were collected. Serum levels of interleukin-1β and interleukin-18 were measured. Micro-CT scans were performed on the distal femur. Hematoxylin-eosin staining was used to observe histological changes in the femur. Western blot assay was conducted to detect the expression of tripartite motif-containing protein 24 (TRIM24), NLRP3, and cleaved caspase-1 in the femur. (2) Rat bone marrow mesenchymal stem cells at the logarithmic growth stage were divided into four groups: blank group with no treatment, asiaticoside group treated with 20 µmol/L asiaticoside, asiaticoside+empty carrier group treated with 20 µmol/L asiaticoside for 48 hours after transfection with the empty vector plasmid for 48 hours, and asiaticoside+NLRP3 overexpression group treated with 20 µmol/L asiaticoside for 48 hours after transfection with the NLRP3 overexpression plasmid for 48 hours. After 7 days of inducing osteogenic differentiation, the activity of alkaline phosphatase and mRNA expression of osteopontin, osteocalcin, TRIM24, and NLRP3 were detected. 
RESULTS AND CONCLUSION: (1) Animal experiment: The levels of interleukin-1β and interleukin-18 in the low-dose asiaticoside group, high-dose asiaticoside group, and positive control group were all lower than those in the model group (P < 0.05). The levels of interleukin-1β and interleukin-18 in the high-dose asiaticoside + activator group were higher than those in the high-dose asiaticoside group (P < 0.05). Micro-CT scans and hematoxylin-eosin staining revealed that compared with the model group, the microstructure and histomorphology of the femur were significantly improved in the low-dose and high-dose asiaticoside groups as well as in the positive control group. However, NLRP3 activator partially inhibited the effects of high-dose asiaticoside. Compared with the model group, the low-dose asiaticoside group, high-dose asiaticoside group, and positive control group showed increased expression of TRIM24 protein (P < 0.05) and decreased expression of NLRP3 and cleaved caspase-1 protein (P < 0.05). Compared with the high-dose asiaticoside group, the high-dose asiaticoside + activator group showed lower protein expression of TRIM24 (P < 0.05), but higher protein expression of NLRP3 and cleaved caspase-1 (P < 0.05). (2) Cell experiment: The alkaline phosphatase activity in the asiaticoside group was higher than that in the blank group and the asiaticoside + NLRP3 overexpression group (P < 0.05). RT-PCR revealed that the asiaticoside group showed higher mRNA expression levels of osteopontin, osteocalcin, and TRIM24 but lower NLRP3 mRNA expression compared with the control group and the asiaticoside + NLRP3 overexpression group (all P < 0.05). To conclude, asiaticoside may promote osteogenic differentiation of bone marrow mesenchymal stem cells and delay osteoporosis progression in osteoporotic rats by upregulating TRIM24 and inhibiting NLRP3 expression.
