Biosci Rep:LncRNA DANCR通过抑制lncRNA-LET促进胃癌细胞的迁移和侵袭

2017-11-09 MedSci MedSci原创

胃癌(GC)是最常见的胃肠道恶性肿瘤之一。长链非编码RNA(lncRNA)DANCR是最新鉴定的致癌lncRNA。然而,DANCR在GC方面的功能作用和分子机制尚不清楚。在本研究中,我们研究了DANCR在GC细胞迁移和侵袭中的生物学功能和潜在机制。结果显示,DANCR的敲低抑制了GC细胞的迁移和侵袭,而DANCR的过表达则表现出相反的效果。进一步的研究表明,lncRNA-LET是DANCR的真正靶

胃癌(GC)是最常见的胃肠道恶性肿瘤之一。长链非编码RNA(lncRNA)DANCR是最新鉴定的致癌lncRNA。然而,DANCR在GC方面的功能作用和分子机制尚不清楚。

在本研究中,我们研究了DANCR在GC细胞迁移和侵袭中的生物学功能和潜在机制。结果显示,DANCR的敲低抑制了GC细胞的迁移和侵袭,而DANCR的过表达则表现出相反的效果。进一步的研究表明,lncRNA-LET是DANCR的真正靶基因。此外,DANCR高表达和lncRNA-LET低表达与癌细胞淋巴结转移及晚期临床分期明显相关。DANCR与EZH2和HDAC3相关联,从而表观沉默lncRNA-LET,然后调节GC的迁移和侵袭。

总之,这些发现表明,DANCR-lncRNA-LET轴在GC细胞迁移和侵袭中发挥了重要作用,并揭示了lncRNA-LET沉默的新的表观遗传机制。

PLoS One:外泌体lncRNA GAS5调节动脉粥样硬化中巨噬细胞和血管内皮细胞的凋亡

目前普遍认为动脉粥样硬化是血管壁的慢性脂质引起的炎症。氧化低密度脂蛋白(oxLDL)驱动涉及巨噬细胞和内皮细胞(ECs)的动脉粥样化形成的发生。本研究既往研究发现表明,患者和动物模型收集的动脉粥样硬化斑块中,长非编码RNA生长停滞特异性5(lncRNA GAS5)的表达明显增加。本研究中,研究发现敲除lncRNA GAS5可降低oxLDL处理的THP-1细胞的凋亡。相反,oxLDL刺激后,lncR

Biol Res:lncRNA BANCR上调与结直肠癌淋巴结转移及预后不良相关

越来越多的证据支持长链非编码RNA(lncRNA)在结直肠癌(CRC)的发展、进展和预后中发挥重要作用。然而,关于BRAF激活的非编码RNA(BANCR)在CRC中的临床意义知之甚少。本研究旨在探讨lncRNA BANCR在CRC患者中的临床应用价值。采用定量实时荧光定量PCR检测了106例CRC组织和65例癌旁正常组织中lncRNA BANCR的表达。结果显示,lncRNA BANCR在CRC组

Nat Med:为什么癌症无法治愈?研究给出新的解释!

靶向抗癌疗法西妥昔单抗和帕尼单抗是治疗晚期结肠直肠癌的主要手段,是美国癌症相关死亡的第二大原因。然而,许多患者具有遗传突变的肿瘤,使得它们对这些抗表皮生长因子受体(EGFR)单克隆抗体具有抗性,或者癌症在治疗期间产生抗性。寻求了解内在和获得性抗性机制的研究人员把研究重点集中在基因突变上,例如在致癌基因KRAS中激活突变。
