白细胞介素-6受体亚单位gp80和gp130在骨质疏松症中的基因表达(英文)

目的观察骨质疏松症骨髓白细胞介素-6(IL-6)受体(IL-6R)亚单位gp80和gp130基因表达的变化,探讨IL-6R复合系统在雌激素缺乏所致骨质疏松中的作用。方法12周龄雌性SD大鼠20只犤体重(200±20)g犦随机分为骨质疏松组(10只)和空白对照组(10只)。分别于造模后0、12周,测定大鼠骨髓gp80和gp130mRNA水平。结果gp130mRNA水平(pg/μgtotalRNA):术后0、12周空白对照组无明显变化犤(80±3)和(82±4),t=0.85,P>0.05犦,骨质疏松组明显增加犤(80±3)和(290±40),t=6.46,P<0.01犦。gp80mRNA水平(pg/μgtotalRNA):术后0、12周空白对照组无明显变化增加犤(85.4±2.7)和(85.6±2.8),t=0.35,P>0.05犦,骨质疏松组明显增加犤(85.2±2.7)和(210±40),t=6.32,P<0.01犦。结论卵巢切除所致骨质疏松大鼠骨髓IL-6R亚单位gp80和gp130基因表达增加。

Expressions of the gp80 and gp130 subunits of the IL- 6 receptor in the bone marrow of osteoporosis

Aim To study the change of the expression of the gp80 and gp130 subunits of the IL- 6 receptor (IL- 6R)in the osteoporotic bone marrow, to explore the role of IL- 6 receptor system in the osteoporosis resulted from the loss of estrogen.Methods Twenty female 12- week old SD rats weight (200± 20) g] were randomly divided into 2 groups: the osteoporosis model group (10 rats),the control group (10 rats).Respectively in the 0th ,12th week after ovariectomy to analyze the levels of gp80 and gp130.Results In the 0th,12th week after ovariectomy,the level of gp130 (pg/μ g total RNA): the control group's level had no significant change (80± 3 vs 82± 4,t=0.85,P >0.05), while the osteoporosis group's level became significant higher (80± 3 vs 290± 40,t=6.46,P< 0.01).In the 0th ,12th week after ovariectomy, the level of gp80(pg/μ g total RNA): the control group's level had no significant change (85.4± 2.7 vs 85.6± 2.8,t=0.35,P >0.05), while the osteoporosis group's level became significant higher (85.4± 2.7 vs 210± 40,t=6.32,P< 0.01).Conclusion There was a significant increase of the expressions of gp130 and gp80 in the bone marrow of osteoporotic rat.
