Oncotarget:研究揭示了CCAT1和SGK3在神经性疼痛中的关键作用

2017-11-28 MedSci MedSci原创

神经性疼痛是由躯体感觉神经系统的功能障碍或原发性损伤引起的。长链非编码RNAs(lncRNA)在神经性疼痛的发展中起重要作用。然而,lncRNA结肠癌相关转录物-1(CCAT1)在神经性疼痛中的作用目前尚未见报道。双侧坐骨神经慢性压迫性损伤(bCCI)被认为是长期机械性超敏反应和冷异常性疼痛,是神经性疼痛患者的典型症状。本研究中,研究人员发现bCCI大鼠脊髓背角、背根神经节(DRG)、海马和前扣带

神经性疼痛是由躯体感觉神经系统的功能障碍或原发性损伤引起的。长链非编码RNAs(lncRNA)在神经性疼痛的发展中起重要作用。然而,lncRNA结肠癌相关转录物-1(CCAT1)在神经性疼痛中的作用目前尚未见报道。

双侧坐骨神经慢性压迫性损伤(bCCI)被认为是长期机械性超敏反应和冷异常性疼痛,是神经性疼痛患者的典型症状。本研究中,研究人员发现bCCI大鼠脊髓背角、背根神经节(DRG)、海马和前扣带皮层(ACC)CCAT1的表达降低。bCCI大鼠术后14天出现冷异常性疼痛。

进一步研究表明,lncRNA CCAT1降低了NGF分化的PC12细胞中miR-155的表达,增强了血清和糖皮质激素调节蛋白激酶3(SGK3)的表达。研究发现miR-155在bCCI损伤大鼠脊髓背角、DRG、海马和ACC中表达增加。但SGC3在bCCI损伤大鼠脊髓背角、DRG、海马和ACC中的表达下调。此外,lncRNA CCAT1过表达可以缓解疼痛阈值,抑制SGK3的表达可以挽救这一效应。

总之,这些结果提示了CCAT1和SGK3在神经性疼痛中的关键作用。
