Pancreatic ductal adenocarcinoma (PDAC) remains a very challenging malignancy. Disease is diagnosed in an advanced stage in the vast majority of patients, and PDAC cells are often resistant to conventional cytotoxic drugs. Targeted therapies have made no progress in the management of this disease, unlike other cancers. microRNAs (miRs) are small non-coding RNAs that regulate the expression of multitude number of genes by targeting their 3'-UTR mRNA region. Aberrant expression of miRNAs has been linked to the development of various malignancies, including PDAC. In PDAC, a series of miRs have been defined as holding promise for early diagnostics, as indicators of therapy resistance, and even as markers for therapeutic response in patients. In this mini-review, we present an update on the various different miRs that have been defined in PDAC biology.
胰腺导管腺癌(PDAC)仍然是一种极具挑战性的恶性肿瘤。绝大多数患者在疾病晚期才被诊断出来,而且PDAC细胞通常对传统细胞毒性药物具有抗性。与其他癌症不同,靶向治疗在这种疾病的治疗中没有取得进展。微小RNA(miRs)是一类小的非编码RNA,通过靶向基因的3'-UTR mRNA区域来调节众多基因的表达。miRNAs的异常表达与包括PDAC在内的各种恶性肿瘤的发生发展有关。在PDAC中,一系列miRs已被确定有望用于早期诊断、作为治疗抗性的指标,甚至作为患者治疗反应的标志物。在本综述中,我们介绍了在PDAC生物学中已被确定的各种不同miRs的最新情况。
