Epithelial ovarian cancer (EOC) is the leading cause of death among all gynecological malignancies. Despite the technological and medical advances over the past four decades, such as the development of several biological markers (mRNA and proteins biomarkers), the mortality rate of ovarian cancer remains a challenge because of its late diagnosis, which is specifically attributed to low specificities and sensitivities. Under this compulsive scenario, recent advances in expression biology have shifted in identifying and developing specific and sensitive biomarkers, such as microRNAs (miRNAs) for cancer diagnosis and prognosis. MiRNAs are a novel class of small non-coding RNAs that deregulate gene expression at the posttranscriptional level, either by translational repression or by mRNA degradation. These mechanisms may be involved in a complex cascade of cellular events associated with the pathophysiology of many types of cancer. MiRNAs are easily detectable in tissue and blood samples of cancer patients. Therefore, miRNAs hold good promise as potential biomarkers in ovarian cancer. In this review, we attempted to provide a comprehensive profile of key miRNAs involved in ovarian carcinoma to establish miRNAs as more reliable non-invasive clinical biomarkers for early detection of ovarian cancer compared with protein and DNA biomarkers.
上皮性卵巢癌(EOC)是所有妇科恶性肿瘤中导致死亡的主要原因。尽管在过去四十年里技术和医学取得了进步,比如开发了多种生物标志物(mRNA和蛋白质生物标志物),但由于卵巢癌诊断较晚,其死亡率仍然是一个挑战,而这又具体归因于其低特异性和敏感性。在这种紧迫的情况下,表达生物学的最新进展已转向识别和开发特异性和敏感性的生物标志物,如用于癌症诊断和预后的微小RNA(miRNA)。miRNA是一类新型的小非编码RNA,通过翻译抑制或mRNA降解在转录后水平上调控基因表达。这些机制可能参与了与多种癌症病理生理学相关的复杂细胞事件级联反应。miRNA在癌症患者的组织和血液样本中易于检测。因此,miRNA作为卵巢癌潜在生物标志物具有良好前景。在本综述中,我们试图提供参与卵巢癌的关键miRNA的全面概况,以确立miRNA作为比蛋白质和DNA生物标志物更可靠的非侵入性临床生物标志物用于卵巢癌的早期检测。
