    • 摘要: 目的探讨microRNA-181b(miR-181b)能否通过靶向调控NDRG2参与2型糖尿病胰岛素分泌的调节。方法选用小鼠胰岛β细胞进行体外传代培养,构建NDRG2野生型(NDRG2^(WT)-1uc)与突变型(NDRG2^(MUT)-1uc)荧光素酶报告基因质粒并进行转染,转染结束后进行双荧光素酶报告分析。构建NDRG2过表达和敲低质粒并转染小鼠胰岛β细胞,检测NDRG2 mRNA和蛋白表达、胰岛素分泌量。未转染的小鼠胰岛β细胞培养48 h后采用实时荧光定量聚合酶链反应检测miR-181b和NDRG2 mRNA的表达。采用葡萄糖刺激的胰岛素释放试验检测5 mmol/L和20 mmol/L葡萄糖条件下的小鼠胰岛β细胞分泌的胰岛素。结果(1)荧光素酶报告基因实验检测发现,各组相对荧光强度比较,差异有统计学意义(P0.05);在20 mmol/L葡萄糖条件下,过表达对照组胰岛素分泌量高于过表达组(P0.05);在20 mmol/L葡萄糖条件下,敲低组胰岛素分泌量高于敲低对照组(P0.05);20 mmol/L葡萄糖组miR-181b相对表达量高于对照组和5 mmol/L葡萄糖组(P0.05)。在20 mmol/L葡萄糖条件下,miR-181b mimics组胰岛素分泌量高于Control组(P<0.05),miR-1b1 inhibitor组胰岛素分泌量低于Control组和miR-181b mimics组(P<0.05)。结论miR-181b可以通过靶向抑制NDRG2的表达来提高胰岛素的分泌。

    • 摘要: 选取30只健康成年的新西兰大白兔,随机均分为快速减压组、控制减压组、假手术组.术后24h评价各组动物行为学评分,检测脑组织含水量、N-myc下游调节基因2(NDRG2)、Caspase-3表达水平以及脑细胞凋亡情况.与假手术组相比,控制减压组和快速减压组中动物学评分、脑组织含水量、Caspase-3的表达水平增加以及脑细胞凋亡程度增加,但NDRG2的表达水平降低;与快速减压组相比,控制减压组中动物行为学评分、脑组织含水量、Caspase-3表达水平以及脑细胞凋亡程度降低,但NDRG2的表达水平增加.控制减压技术通过增加NDRG2的表达减轻了脑水肿程度,抑制了脑细胞凋亡程度,从而减轻了脑缺血再灌注的损伤程度,改善脑损伤预后.

Results Compared with sham group,the MWT and TWL was significantly decreased and reduced in SNL group 1,3,7,10,14,21 d and 3,7,10,14,21 d after surgery respectively(P<0.01).Com-pared with 1 d before surgery,protein content and mRNA expression of NDRG2 in the spinal dorsal horn of the SNL group were significantly decreased 1 d after surgery,and they were significantly in-creased on the 7,10,14,and 21 d after operation(P<0.01).Compared with group CS,the MWT and TWL were significantly decreased and reduced in group SS and group SA 1,3,7 and 10 d after surgery(P<0.05).MWT and TWL on 7 and 10 d were increased significantly in group SA (P<0.05)compared with group SS.Compared with group CS,protein content and mRNA expression of NDRG2 in the spinal dorsal horn of group CA were significantly decreased,and increased significantly in group SS 10 d after surgery(P<0.05).Compared with group SS,protein content and mRNA ex-pression of NDRG2 in the spinal dorsal horn of group SA were significantly decreased.Compared with group CS,the protein content of GFAP in spinal dorsal horn of group CA,group SS and group SA were increased significantly 10 d after surgery (P<0.05).Conclusion Intrathecal injection of AD-Ndrg2-RNAi significantly inhibits neuropathic pain caused by spinal cord ligation in rats,suggesting that NDRG2 in astrocytes is involved in the development and progression of neuropathic pain.

    • 摘要: 目的:探讨NDRG2在上皮性卵巢癌中的表达及其与预后的关系.方法:收集新鲜的上皮性卵巢癌和正常卵巢组织各15例,采用real-time PCR检测和比较其NDRG2 mRNA的表达.收集上皮性卵巢癌病理切片96例进行免疫组化检测其NDRG2蛋白的表达,并收集患者的临床病理资料,随访患者的生存情况,分析NDRG2蛋白的表达与上皮性卵巢癌患者临床病理特征和预后的关系.结果:上皮性卵巢癌组织中NDRG2 mRNA和蛋白的表达均显著低于正常卵巢组织(P<0.05).NDRG2在上皮性卵巢癌组织中的表达随着上皮性卵巢癌病理分期的升高而降低,而且其表达降低和患者不良预后显著相关(P=0.002),但其表达和不同上皮性卵巢癌的病理类型、分化程度以及年龄均无明显相关性.去除手术病理分期的影响,NDRG2表达下调和肿瘤细胞减灭术的满意程度以及术后规范化疗是三个影响上皮性卵巢癌预后的重要因素.结论:NDRG2在上皮性卵巢癌中的表达下降,并与患者的不良预后呈显著正相关.%Objective:To study the expression of NDRG2 in epithelial ovarian cancer(EOC) and its correlation with the prognosis of EOC patients.Methods:15 cases of fresh epithelial ovarian cancer and 15 cases of normal ovarian tissue were collected.The mRNA expression of NDRG2 were detected and compared by real-time PCR.96 cases of epithelial ovarian cancer pathological sections were collected and the expression of NDRG2 protein was detected by immunohistochemistry,the clinicopathological characteristics and survival of patients were statistically analyzed.Results:The mRNA and protein expression of NDRG2 in the EOC tissue were significantly lower than those of the normal ovarian tissue (P<0.05).The protein expression of NDRG2 decreased with the increase of pathological staging of EOC and was significantly correlated with the poor prognosis of EOC patients (P=0.002).However,no obvious correlation was found of the protein expression of NDRG2 with pathological type,differentiated degree and age (P>0.05).Excluding the effect of surgical-pathological staging,decrease of NDRG2 expression,satisfaction of cytoreductive surgery and postoperative standard chemotherapy were influencing factors for the prognosis of EOC patients.Conclusion:The expression of NDRG2 was decreased in the EOC tissue and was positively correlated with theprognosis of EOC patients.

    • 摘要: Objective:To explore the effect and mechanism of NDRG2 on the histone acetylation in U87-MG cells and provide new ideas for the treatment of glioma.Methods:NDRG2 overexpression was mediated by lentivirus,and the level ofhistone acetylation was measured by Western blot using acetylation antibodies in U87-MG cells.ELISA was used to evaluated the effect on acetyl-CoA metabolism ofNDRG2 overexpression.The AKT-ACLY pathway was detected to illustrated this mechanism.Results:The phosphorylation of AKT and ACLY in U87MG cell were significantly down-regulated with the overexpression of NDRG2,resulting in change of acetyl-CoA/CoA ratio.The histone acetylation level was down-regulated,which had an effect on the proliferation of glioma cells.Conclusions:NDRG2 might participate in the metabolism of acetyl-CoA and regulate the histone acetylation,which could further suppress the proliferation ofU87-MG glioma cell.%目的:探讨NDRG2对胶质瘤U87-MG细胞组蛋白乙酰化的影响,从代谢组学角度明确其抑癌机制,为胶质瘤治疗提供新思路.方法:利用慢病毒介导的外源性NDRG2基因在胶质瘤U87-MG细胞株中过表达,并采用MTT检测其对胶质瘤U87-MG细胞增殖的影响,采用Western blot技术研究其对胶质瘤U87-MG细胞组蛋白乙酰化及AKT-ACLY通路磷酸化状态的影响,并使用酶联反应检测胞内乙酰辅酶A的水平.结果:NDRG2在胶质瘤U87-MG细胞中外源过表达可降低AKT及下游分子ACLY的磷酸化水平,减少胞内乙酰辅酶A的合成,抑制组蛋白乙酰化.结论:NDRG2可能通过抑制AKT通路,减少组蛋白乙酰化,进而抑制胶质瘤U87-MG细胞增殖.
