骨保护素(Osteoprotegerin, OPG)是骨保护素配体(Osteoprotegerin- ligand, OPGL)的可溶性受体,在成骨细胞上表达,介导破骨细胞分化信号。在本研究中,我们证明IL-1 α处理8小时后MG-63细胞中的OPG mRNA水平呈剂量依赖性增加(在25 U/ml时比对照组增加338 +/- 53%)。在相似的培养条件下,白细胞介素-6 (IL-6)不影响OPG mRNA水平。时间过程研究表明,IL-1 α (25 U/ml)可引起MG-63细胞中OPG mRNA水平的短暂升高,并在处理4 h后达到峰值。OPG转录物在0.5 h时出现在hOB细胞中,在IL-1 α处理24小时后仍然存在。在MG-63细胞中,基础或IL-1 α诱导的OPG mRNA水平均未被翻译抑制剂环己亚胺改变。这些结果提示成骨细胞中OPG的表达可能受IL-1 α的调控。
Osteoprotegerin (OPG) is a soluble receptor for the Osteoprotegerin-Ligand (OPGL) which is expressed on osteoblasts and mediates the signal for osteoclast differentiation. In the present study we demonstrate that OPG mRNA levels in MG-63 cells are increased in a dose-dependent manner after 8 h of treatment with IL-1 alpha (338 +/- 53% over control at 25 U/ml). Interleukin-6 (IL-6), under similar culture conditions, does not affect OPG mRNA levels. Time-course studies show that IL-1 alpha (25 U/ml) causes a transient increase of OPG mRNA levels in MG-63 cells, peaking after 4 h of treatment. An increase of the OPG transcript occurs in hOB cells at 0.5 h which is still present after 24 h of IL-1 alpha treatment. In MG-63 cells neither basal-nor IL-1 alpha-induced OPG mRNA levels are altered by the translational inhibitor cycloheximide. These results suggest that expression of OPG in osteoblasts may be regulated by IL-1 alpha.
