This miRNA dose-dependent target selection was also confirmed in other target genes, including CCND1, CDKN1 and E2F1. After overexpressing let-7a-7f or the miR-17-92 clusters at wide-ranging doses, the target genes displayed a nonlinear correlation to the transfected miRNA.

MicroRNA-17-92 reglerar myoblastproliferation och -differentiering genom att rikta sig till ENH1 / Id1-signalaxeln.

2017-02-27 · In this study, we investigated miRNA mechanism of action in lymphocytes by conducting an integrated analysis of the transcriptomes and translatomes of primary B cells from miR-17~92 transgenic and knockout mice. The miR-17~92 family consists of three miRNA clusters: miR-17~92, miR-106a~363, and miR-106b~25 . Notably, Loven and colleagues showed that N-myc also binds to E-boxes of the mir-17-92 paralogous miRNA clusters mir-106b-25 (chromosome 7) and mir-106a-363 (chromosome X), enabling a concerted action of N-myc–activated miRNAs to synergize N-myc functions. To investigate whether this miRNA panel might be used as a non-invasive biomarker, miR-17/92 cluster expression profile was analyzed in peripheral blood. Cell-free plasma and plasma exosomes of RC patients were examined at the diagnosis and, to be able to associate miRNA profiles with treatment outcomes, 6 and 12 months later, spanning thus the period of chemotherapy and recovery. miRNA miR‐17‐92 cluster is differentially regulated in the imiqumod‐treated skin but is not required for imiqumod‐induced psoriasis‐like dermatitis in mice Dinghong Wu Department of Dermatology, Guangdong provincial Hospital of Chinese Medicine, Guanghzou, China Before plant miRNA:miRNA* duplexes are transported out of the nucleus, its 3' overhangs are methylated by a RNA methyltransferaseprotein called Hua-Enhancer1 (HEN1).

We previously reported amplification and overexpression of the miR-17-92 miRNA cluster at 13q31.3 in lung cancers, as well as growth inhibition by treatment with antisense oligonucleotides against miR-17 Adipogenesis involves cell proliferation and differentiation, both of which have been shown to be regulated by micro (mi)RNA. During mouse preadipocyte 3T3L1 cell differentiation, we found that miR-17-92, a miRNA cluster that promotes cell proliferation in various cancers, was significantly up-regulated at the clonal expansion stage of adipocyte differentiation. Microarray profiling of cultured oligodendrocytes identified the miR-17-92 miRNA cluster as highly enriched in oligodendrocytes. We specifically deleted the miR-17-92 cluster in oligodendrocytes using 2,3 -cyclic nucleotide 3 phosphodiesterase (Cnp)-Cre mice. Absence of miR-17-92 leads to a reduction in oligodendrocyte number in vivo and we Whether miRNA-regulated neurogenesis contributes to cognition remains poorly understood. 17-92flox/flox mice, leading to the ablation of the miR-17-92 cluster O’Donnell等人单独证明了mir-17-92基因簇是一组可能的肿瘤相关的基因。他们用miRNAs芯片筛选过表达MYC，B细胞系P493-6中miRNA表达变化。他们发现MYC诱导了mir-17-92的表达，而这些miRNAs可以抑制E2F1的翻译。 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.

Endothelial cell death is linked to vascular diseases such as atherosclerosis and tissue ischemia. miRNA-17-92 (miR-17-92) is a multiple functional oncogenic miRNA cluster which plays vital roles in tumor angiogenesis and tissue development. However, its role in regulation of endothelial cell ferrop …

Histone deacetylase 9 promotes angiogenesis by targeting the antiangiogenic microRNA-17-92 cluster in endothelial cells. Arterioscler Thromb Vasc Biol 3

Here we showed that imiquimod (IMQ) differentially regulates the expression of miR-17-92 cluster in the mouse skin, upregulating miR-17 and miR- 19 families and downregulating miR-92. 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.

We previously reported amplification and overexpression of the miR-17-92 miRNA cluster at 13q31.3 in lung cancers, as well as growth inhibition by treatment with antisense oligonucleotides against miR-17-5p and miR-20a, constituents of miR-17-92, specifically in miR-17-92-overexpressing lung cancer cell lines.

miRNA miR-17-92 was reported to promote the differentiation of Th1 and Th1 cells and to regulate cell proliferation and apoptosis. Here we showed that imiquimod (IMQ) differentially regulates the expression of miR-17-92 cluster in the mouse skin, upregulating miR-17 and miR- 19 families and downregulating miR-92. Recently, genome-wide miRNA profiling showed that various miR-17-92 family members were significantly upregulated in MSS cancers, reliably distinguishing MSI from MSS CRCs. 36 Likewise, Valeri et al 37 found that overexpression of miR-155 downregulated … Regulation of miRNA 219 and miRNA clusters 338 and 17-92 in oligodendrocytes Omar de Faria Jr. 1,2,3 , Qiao-Ling Cui 1,3 , Jenea M. Bin 1,2 , Sarah-Jane Bull 1,2 ,Timothy E. Kennedy 1,2 , Here, we outline the experimental procedures involved in ribonuclease structural probing of the ~800 nucleotide miRNA cluster miR-17~92 that were used in our previous report of regulation of miRNA biogenesis by pri-miRNA tertiary structure ( Fig. 1 ) [ 10 ].

As discussed, the mir-17-92 cluster has been proposed to have a functional relationship with Patched signalling. An abnormal functioning of which can induce the GNP tumours typical of Medullablastoma. This hypothesis was arrived at by taking miRNA expression profiles of GNP-like tumour cells from mouse mutants.
