Cell Death Dis:中国科学家发现抑制鼻咽癌生长转移新机制

2015-01-30 佚名 生物谷

近日,国际生物学期刊cell death &disease在线发表了来自中山大学一研究小组的最新研究成果。他们通过基因芯片分析发现miR-34c在鼻咽癌(NPC)中发生下调,并通过实验证明miR-34c能够通过直接抑制原癌基因MET表达抑制鼻咽癌肿瘤生长和转移。这项研究对治疗鼻咽癌提供了机制上的借鉴意义。 研究人员通过对NPC细胞系和病人组织样本进行分析发现,miR-34c在细胞和组织内均发生明

近日,国际生物学期刊cell death &disease在线发表了来自中山大学一研究小组的最新研究成果。他们通过基因芯片分析发现miR-34c在鼻咽癌(NPC)中发生下调,并通过实验证明miR-34c能够通过直接抑制原癌基因MET表达抑制鼻咽癌肿瘤生长和转移。这项研究对治疗鼻咽癌提供了机制上的借鉴意义。

研究人员通过对NPC细胞系和病人组织样本进行分析发现,miR-34c在细胞和组织内均发生明显表达下调。通过在细胞系内过量表达miR-34c发现,NPC细胞存活能力,集落形成,细胞迁移及侵袭能力都受到明显抑制,同时体内实验也证明miR-34c过表达能够抑制肿瘤生长及肺转移。研究人员通过实验发现miR-34c能够直接作用于原癌基因MET,miR-34c过表达能够明显降低MET的mRNA和蛋白水平。在细胞内敲低MET能够抑制NPC细胞增殖,迁移和侵袭,同时恢复MET表达能够改变miR-34c对肿瘤细胞的抑制效应。除此之外,研究人员还发现了一种能够恢复miR-34c表达的化学分子。
 
综上所述,该项研究发现miR-34c能够通过影响MET表达抑制鼻咽癌肿瘤生长和转移,关于miR-34c/MET新通路的发现或许可以为进一步研究NPC发展机制以及开发治疗NPC的药物提供重要借鉴意义。
