Whereas miR-92a was recently identified as negative regulator of angiogenesis, the specific functions of the other members of the cluster are less clear. the miR-17~92 cluster control monocyte differentiation and maturation.16 The miR-17~92 cluster in develop-ment. In an elegant study, Ventura et al. studied the function of the miR-17~92 cluster and its paralogs miR-106a~363 and miR-106b~25 by generating mice deficient for each of these miRNA clusters.14 While The miR-17-92 cluster (encoding miR-17, -18a, -19a/b, -20a, and miR-92a) is highly expressed in tumor cells and is up-regulated by ischemia. Whereas miR-92a was recently identified as negative regulator of angiogenesis, the specific functions of the other members of the cluster are less clear. miR-17∼92 miRNA Cluster Is Up-Regulated in Mouse Models of PKD. To identify miRNAs that are differentially expressed between cystic kidneys and normal kidneys, we performed miRNA microarrays using RNA from kidneys of control and kidney-specific-cadherin (Ksp)/cre;Kif3a F/F (Kif3a-KO) mice, an animal model of PKD. Many RNAs are processed into biologically active transcripts, the aberrant expression of which can contribute to disease phenotypes. For example, the primary microRNA-17-92 (pri-miR-17-92) cluster contains six microRNAs (miRNAs) that collectively act in several disease settings.

In the present study, by specific ablation of this cluster in Conditional KO of the miR‐17‐92 cluster in NSCs impairs adult neurogenesis. The miR‐17‐92 cluster incorporates a family composed of 6 miRNAs (miR‐17, miR‐18a, miR‐19a, miR‐20a, miR‐19b‐1, and miR‐92a), which is highly conserved in humans and rodents (Fig. 1A). miRNA-17–92 cluster plays a role in Y79 cell proliferation. Invasion— A matrigel invasion assay was performed on the Y79 cells after 48 h of treatment with antagomirs. Adipogenesis involves cell proliferation and differentiation, both of which have been shown to be regulated by micro (mi)RNA.

A high-level of miR-17-92 cluster expression also results in … 2007-02-01 Interestingly, deletion or overexpression of miR-17- 92 cluster in keratinocytes, or deletion of miR-17-92 in T cells did not significantly affect IMQ-induced psoriasis- like dermatitis develop-ment in the mutant mice compared with wild-type littermates. Thus, miRNA miR-17- 92 cluster 2013-06-25 Members of the miRNA gene cluster can coordinate the regulation of certain processes or play a similar role in the same biological process, ensuring biological activity occurs in a normal and orderly fashion. miR-17-92 encodes a miRNA precursor and produces 7 mature miRNA molecules that belong to 4 miRNA … 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 … Thus, miRNA miR‐17‐92 cluster may not be a key factor regulating imiqumod‐induced psoriasis‐like dermatitis. 1 Background. Psoriasis is an immune‐mediated inflammatory skin disease, characterized by keratinocyte hyperproliferation and altered differentiation, 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.

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. Now more than 300 miRNA clusters are found in the human genome, including miR-183-96-182 cluster, miR-35-41 cluster, miR-17-92 cluster and so on.

av K Edvardsson · 2011 — miRNA pool in colon cancer cells. In particular, we found the oncogenic miR-17-92 cluster to be downregulated and proposed this to be a consequence of the  MicroRNA Expression Profile Reveals miR-17-92 and miR-143-145 Cluster in Synchronous Colorectal Cancer2015Ingår i: Medicine (Baltimore, Md.), ISSN  Histone deacetylase 9 promotes angiogenesis by targeting the antiangiogenic microRNA-17-92 cluster in endothelial cells.

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.

The miR-17-92 cluster is also crucial in the development of B-NHL. Tagawa et al documented that c-Myc can not only promote the transcription of miR-17-92 cluster, but can also act as a target of the miR-17-92 cluster. A high-level of miR-17-92 cluster expression also results in the poor survival rate of patients with MCL .

miRNA-17–92 cluster plays a role in Y79 cell proliferation.

miRNA clusters play important roles by controlling various cellular processes. 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 The miR-17-92 gene cluster, a polycistron encoding six microRNAs (miRNA), is frequently overexpressed in human cancers and has been shown to promote several aspects of oncogenic transformation, including evasion of apoptosis. In the current study, we show a new role of miR-17-92 in inhibiting oncogenic ras -induced senescence. 2007-02-01 · mir-17–92 is a good example for an oncogenic miRNA.
