miR-17-92 Cluster Promotes Cholangiocarcinoma Growth

miR-17~92 miRNA cluster promotes kidney cyst growth in polycystic kidney disease.

Polycystic kidney disease (PKD), the most common genetic cause of chronic kidney failure, is characterized by the presence of numerous, progressively enlarging fluid-filled cysts in the renal parenchyma. The cysts arise from renal tubules and are lined by abnormally functioning and hyperproliferative epithelial cells. Despite recent progress, no Food and Drug Administration-approved therapy is ...

New Insights Into miR-17-92 Cluster Regulation and Angiogenesis.

miR-17-92 Cluster of MicroRNAs Confers Tumorigenicity

Downlo ammalian cells, activation of oncogenes usually triggers innate tumor-suppressing defense mechanisms, ing apoptosis and senescence, which are compromised by additional mutations before cancers are develThe miR-17-92 gene cluster, a polycistron encoding six microRNAs (miRNA), is frequently overexpressed an cancers and has been shown to promote several aspects of oncogenic transformation, ...

MicroRNA Expression Profile Reveals miR-17-92 and miR-143-145 Cluster in Synchronous Colorectal Cancer

The expression of abnormal microRNA (miRNA, miR) is a ubiquitous feature of colorectal cancer (CRC). The pathological features and clinical behaviors of synchronous CRC have been comprehensively described; however, the expression profile of miRNA and small nucleolar RNA (snoRNA) in synchronous CRC has not been elucidated. In the present study, the expression profile of miRNA and snoRNA in 5 syn...

miR-21 targets 15-PGDH and promotes cholangiocarcinoma growth.

UNLABELLED miRNAs are a group of small, noncoding RNAs that modulate the translation of genes by binding to specific target sites in the target mRNA. This study investigated the biologic function and molecular mechanism of miR-21 in human cholangiocarcinoma. In situ hybridization analysis of human cholangiocarcinoma specimens showed increased miR-21 in cholangiocarcinoma tissue compared with th...
