Recent research identifies the miR-17-92 cluster as a crucial player in the development of the immune system, the heart, the lung, and oncogenic events.

In humans, the activating mutations of miR-17~92 have been identified in non-Hodgkin's lymphoma, whereas the miRNA constituents of the clusters are overexpressed in a multiple cancer types. [8] [9] [10] High level expression of miR-17 family members induces cell proliferation, whereas deletion of the miR-17~92 cluster, in mice, is lethal and causes lung and lymphoid cell developmental defects

16 Particularly, miR-17 and miR-20a were shown to control cellular proliferation and apoptosis by targeting the E2F The miRNA-17-92 cluster is also predicted to provide important supplementary tools for tumor classification, determination of the treatment plan and analysis of prognosis by clinicians. For example, the use of miR-17 antagonists represents a novel therapeutic approach to the treatment of chronic lymphocytic leukemia . Usually, miRNA clusters consist of two or three miRNAs, but larger clusters also exist, for example, the miR-17-92 cluster is found on human chromosome 13 and is composed of six miRNAs. miRNA Usually, miRNA clusters consist of two or three miRNAs, but larger clusters also exist, for example, the miR-17-92 cluster is found on human chromosome 13 and is composed of six miRNAs. miRNA clusters play important roles by controlling various cellular processes.

A polycistronic microRNA cluster, miR-17–92, is overexpressed in human lung cancers and enhances cell proliferation Cancer Res , 65 ( 2005 ) , pp. 9628 - 9632 View Record in Scopus Google Scholar The miR-17-92 cluster is a typical highly conserved polycistronic miRNA cluster, which is located in the human chromosome 13 open reading frame 25 (C13orf25), encoding six mature miRNAs, including miR-17, miR-18a, miR-19a, miR-19b, miR-20a and miR-92a (10). Proper miR-17~92 cluster is necessary for normal lung development and alterations in expression are reported in other pulmonary diseases. The overall hypothesis for our work is that altered miRNA expression profiles were significantly different between malignant and benign tissue and between cancer subgroups according to ER− status, grade and molecular subtype.

4A). Overall, the sensitivity and specificity of the combined detection for predicting disease progression in patients with GC were superior to those with each miRNA alone. A polycistronic miRNA cluster miR-17-92 plays a role in the control of cell proliferation and angiogenesis. This cluster consists of seven miRNAs: miR-17-5p, miR-17-3p, miR-18a, miR-19a, miR-19b, miR-20a, and miR-92.

MiR-17-92 cluster is an oncogenic miRNA cluster that is implicated in several cancers, although its role in hepatocarcinogenesis has not been clearly defined. In this study, we show that the miR-17-92 cluster is highly expressed in human hepatocellular carcinoma (HCC) tissues compared to the non-tumorous liver tissues by RT-PCR and in situ hybridization analyses.

Accumulating evidence suggests that expression of miR-17, miR-18a, miR-92a, and miR-106b have been contributed to FAS repression . As a result, we found for the first time that the miR-17-92 cluster, which comprises seven miRNAs and resides in intron 3 of the C13orf25 gene at 13q31.3, is markedly overexpressed in lung cancers, especially with small-cell lung cancer histology.

Psoriasis is an immune‐mediated inflammatory skin disease, characterized by keratinocyte hyperproliferation and altered differentiation, The miR-17~92 cluster in cancer pathogenesis. First evidence that the miR-17~92 cluster may be involved in tumori-genesis was provided by studies showing that the C13orf25 locus, which encodes the primary transcript of the miR-17~92 cluster, is frequently … Increasing evidence indicates that microRNAs (miRNAs) may be critical players in spermatogenesis. The miRNA expression profiles of THY1-enriched undifferentiated spermatogonia were characterized, and members of Mir-17-92 (Mirc1) and its paralog Mir-106b-25 (Mirc3) clusters are significantly downregulated during retinoic acid-induced spermatogonial differentiation, both in vitro and in vivo. The miR-17-92 cluster is often amplified or overexpressed in human cancers and has recently emerged as the prototypical oncogenic polycistron miRNA. The functional analysis of miR-17-92 is intricate by the existence of two paralogues: miR-106a-363 and miR-106b-25. 2018-10-01 2009-12-15 Conditional KO of the miR‐17‐92 cluster in NSCs impairs adult neurogenesis.
