摘要: 目的: 研究雌激素作用下,罗格列酮对RAW264.7向破骨细胞分化的影响及机制。方法: 破骨细胞诱导液核因子-κB受体活化因子配体(receptor activator of nuclear factor-κB ligand,RANKL)诱导鼠巨噬细胞系RAW264.7细胞,加入罗格列酮和/或雌激素诱导5 d,抗酒石酸酸性磷酸酶(tartrate-resistant acid phosphatase,TRAP)染色检测破骨细胞数量,实时荧光定量聚合酶链反应(real-time fluorescent quantitative polymerase chain reaction,qRT-PCR)检测破骨相关基因和转录因子的表达;噻唑蓝(methyl thiazol tetrazolium,MTT)检测罗格列酮和/或雌激素对细胞活性影响。结果: RANKL诱导破骨细胞形成,且在罗格列酮或雌激素刺激下,破骨细胞数量增加,破骨相关基因和转录因子表达增高(P<0.05);但在雌激素作用下罗格列酮抑制破骨细胞形成,破骨相关基因及转录因子表达显著降低(P<0.05)。结论: 雌激素作用下罗格列酮可能通过肿瘤坏死因子受体相关因子6(tumor necrosis factor receptor associated factor 6,TRAF6)和活化T细胞核因子,细胞质1(nuclear factor of activated T-cells, cytoplasmic 1,NFATc1)抑制破骨细胞形成。

Abstract: Objective: To investigate the effect and mechanism of rosiglitazone on osteoclastic differentiation of RAW264.7 cells under estrogen. Methods: The murine macrophage RAW264.7 cells lines were induced by RANKL in the presence or absence of rosiglitazone and/or estrogen for 5 days. The number of osteoclasts was detected by TRAP staining and the expression of osteoclast related genes and transcription factors were detected by qRT-PCR. The effects of rosiglitazone and/or estrogen on cell viability were detected by MTT. Results: Rosiglitazone and estrogen increased cell viability. RANKL induced osteoclast formation and the number of osteoclasts, osteoclast related genes and translation factors increased under rosiglitazone or estrogen stimulation (P<0.05). However, rosiglitazone inhibited osteoclast formation, and osteoclast related genes and translation factors were significantly decreased under estrogen (P<0.05). Conclusion: Rosiglitazone could inhibit osteoclast formation by TRAF6 and NFATc1 under estrogen.
