| 1 | MiRNA as potential biomarkers and therapeutic targets for gastric cancer显示文摘Gastric cancer is one of the leading causes of cancer mortality in the world.Aberrant expression of microRNAs(miRNAs)is the hallmarks of this disease.MiRNAs are endogenous non-coding RNAs that involved in many biological processes(e.g.,cell proliferation,differentiation,apoptosis,invasion and development)through gene repression.Deregulation of miRNA expression in gastric tumors and cancer cell lines have been documented to contribute in tumorigenesis,and the expression signature may correlate with different cancer types and clinicopathological features.Here,we summarized the updated gastric cancer-associated miRNAs and the downstream targets in the process of tumorigenesis.Recently,many researchers make use of the miRNA microarray platform to profile miRNA expression in gastric cancer and correlated with different clinical parameters.Its application on cancer diagnosis,prognosis and predictive treatment response rate are still underway and needs further investigation.Emerging roles of miRNAs with oncogenic or tumor suppressive properties in gastric tumorigenesis were discussed.Epigenetic silencing of miRNA by hypermethylation of promoter CpG island was also observed in gastric cancer.However,detailed mechanisms of how miRNAs regulate gene expression in gastric cancer has not been well studied.In this review,we highlight the upto-date findings on the deregulated miRNAs in gastric cancer,and the potential use of miRNA in the clinical settings,such as diagnostic/prognostic markers and chemotherapeutic tools. | Vivian Yvonne Shin Kent-Man Chu | 2014 | World Journal of Gastroenterology2014，20，30： | 59 |
