| 转化医学是近年来提出的关于基础研究与临床密切结合的新概念，强调实现基础研究成果真正转化为临床实践，为疾病的
诊断和治疗提供先进而有效的方法。胃癌是消化系统常见的恶性肿瘤，其早期诊断与治疗是转化医学研究的重点内容之一。microRNA
(miRNA)是近年来发现的一类长约21-25 个核苷酸的非编码单链小分子RNA，广泛存在于真核生物中。它的发现揭示了一种新的
基因表达调控方式，为胃癌早期诊断与治疗的研究开辟了新路径。miRNA 能够通过与靶基因特异性的结合使其降解或抑制其翻
译，从而对靶基因进行转录后的表达调控。现有越来越多的研究发现，miRNA 与了胃癌的发生、发展、治疗及预后都密切相关，此
文从转化医学角度综述了miRNA 在胃癌中对细胞周期、细胞凋亡、侵袭、转移、放化疗敏感性等的影响的研究进展。 |
| 英文摘要: |
| Translational medicine is a novel concept about combination of basic research and clinical application. It emphasizes
on realizing the translation of basic research into clinical practice and provides advanced and effective method for Diagnosis and treatment
of diseases. Gastric caner is one of the common tumors of digestive system and its diagnosis and treatment is one of the key content
of translational medicine. Recently it has been found that microRNA (miRNA), some kind of Endogenous small single-strand non-coding
RNA molecules (about 21~25-nucleotide), exists widely in eukaryote. The discover of miRNA has shown a new way of gene expression
and it has opened up a new pathearly with ealy diagnosis and treatment of gastric cancer. MiRNA negatively regulate target genes by
binding to it and leading to mRNA degradation or translational repression at posttranscriptional level. More and more research confirmed
that miRNA is closely related to the occurrence, development, treatment and prognosis of gastric caner.Regarding translational medicine,
we summarized recent progress of the role of miRNA in gastic cancer that could influence cell cycle, cell apoptosis, invasion, metastasis
and the sensibility of radiotherapy and chemotherapy. |
