title: MicroRNAs and Gastroenterological Cancers.
abstract: MicroRNAs are small noncoding RNAs that control gene expression. In doing so, they functionally contribute to the maintenance of cellular processes as well as several important features related to cancer development and progression such as cell growth control, differentiation and apoptosis. In fact, recent studies have shown that microRNAs are suitable and effective cancer-related biomarkers since they display altered expression profiles in cancers versus normal tissue. In addition, microRNAs have been associated with cancer progression and outcome. In this review, the current state of knowledge microRNA expression and function in relation to gastroenterological cancers will be addressed. Moreover, the mechanisms to alter their expression and the potential application of microRNAs in clinical settings will also be highlighted. Finally, the challenges involved in translating microRNA research to the clinic will be discussed.
