Abstract
Neutrophils are considered 'first-line defence' cells as they can be rapidly recruited to the site of the immune response. As key components of non-specific immune mechanisms, neutrophils use phagocytosis, degranulation, and formation of neutrophil extracellular traps (NETs) to fight pathogens. Recently, immunoregulatory abilities of neutrophils associated with the secretion of several mediators, including cytokines and extracellular vesicles (EVs) containing, among other components, microRNAs (miRNAs), have also been reported. EVs are small structures released by cells into the extracellular space and are present in all body fluids. Microvesicles show the composition and status of the releasing cell, its physiological state, and pathological changes. Currently, EVs have gained immense scientific interest as they act as transporters of epigenetic information in intercellular communication. This review summarises findings from recent scientific reports that have evaluated the utility of miRNA molecules as biomarkers for effective diagnostics or even as start-points for new therapeutic strategies in neutrophil-mediated immune reactions. In addition, this review describes the current state of knowledge on miRNA molecules, which are endogenous regulators of gene expression besides being involved in the regulation of the immune response.

Abstract
Acute myeloid leukemia (AML) is a heterogeneous and deadly disease characterized by uncontrolled expansion of malignant blasts. Altered metabolism and dysregulated microRNA (miRNA) expression profiles are both characteristic of AML. However, there is a paucity of studies exploring how changes in the metabolic state of the leukemic cells regulate miRNA expression leading to altered cellular behavior. Here, we blocked pyruvate entry into mitochondria by deleting the Mitochondria Pyruvate Carrier (MPC1) gene in human AML cell lines, which decreased Oxidative Phosphorylation (OXPHOS). This metabolic shift also led to increased expression of miR-1 in the human AML cell lines tested. AML patient sample datasets showed that higher miR-1 expression correlates with reduced survival. Transcriptional and metabolic profiling of miR-1 overexpressing AML cells revealed that miR-1 increased OXPHOS, along with key metabolites that fuel the TCA cycle such as glutamine and fumaric acid. Inhibition of glutaminolysis decreased OXPHOS in miR-1 overexpressing MV4-11 cells, highlighting that miR-1 promotes OXPHOS through glutaminolysis. Finally, overexpression of miR-1 in AML cells exacerbated disease in a mouse xenograft model. Together, our work expands current knowledge within the field by uncovering novel connections between AML cell metabolism and miRNA expression that facilitates disease progression. Further, our work points to miR-1 as a potential new therapeutic target that may be used to disrupt AML cell metabolism and thus pathogenesis in the clinic.

Abstract
Echinoderms are marine deuterostomes with fascinating adaptation features such as aestivation and organ regeneration. However, post-transcriptional gene regulation by microRNAs (miRNAs) underlying these features are largely unexplored. Here, using homology-based and de novo approaches supported by expression data, we provided a comprehensive annotation of miRNA genes in the sea cucumber Apostichopus japonicus. By linkage and phylogenic analyses, we characterized miRNA genomic organization, evolutionary history and expression regulation. The results showed that sea cucumbers evolved a large number of new miRNAs, which tended to form polycistronic clusters via tandem duplication that had been especially active in the echinoderms. Most new miRNAs were weakly expressed, but miRNA clustering increased the expression level of clustered new miRNAs. The most abundantly expressed new miRNAs were organized in a single tandem cluster (cluster n2), which was activated during aestivation and intestine regeneration. Overall, our analyses suggest that clustering of miRNAs is important for their evolutionary origin, expression control, and functional cooperation.

Abstract
Evi1 is a transcription factor essential for the development as well as progression of acute myeloid leukemia (AML) and high Evi1 AML is associated with extremely poor clinical outcome. Since targeting metabolic vulnerability is the emerging therapeutic strategy of cancer, we herein investigated a novel therapeutic target of Evi1 by analyzing transcriptomic, epigenetic, and metabolomic profiling of mouse high Evi1 leukemia cells. We revealed that Evi1 overexpression and Evi1‐driven leukemic transformation upregulate transcription of gluconeogenesis enzyme Fbp1 and other pentose phosphate enzymes with interaction between Evi1 and the enhancer region of these genes. Metabolome analysis using Evi1‐overexpressing leukemia cells uncovered pentose phosphate pathway upregulation by Evi1 overexpression. Suppression of Fbp1 as well as pentose phosphate pathway enzymes by shRNA‐mediated knockdown selectively decreased Evi1‐driven leukemogenesis in vitro. Moreover, pharmacological or shRNA‐mediated Fbp1 inhibition in secondarily transplanted Evi1‐overexpressing leukemia mouse significantly decreased leukemia cell burden. Collectively, targeting FBP1 is a promising therapeutic strategy of high Evi1 AML.

Abstract
In this chapter, we discuss different topics always using the microRNA as the guiding thread of the review. MicroRNAs, member of small noncoding RNAs family, are an important element involved in gene expression. We cover different issues such as their importance in the differentiation and maturation of megakaryocytes (megakaryopoiesis), as well as the role in platelets formation (thrombopoiesis) focusing on the described relationship between miRNA and critical myeloid lineage transcription factors such as RUNX1, chemokines receptors as CRCX4, or central hormones in platelet homeostasis like TPO, as well as its receptor (MPL) and the TPO signal transduction pathway, that is JAK/STAT. In addition to platelet biogenesis, we review the microRNA participation in platelets physiology and function. This review also introduces the use of miRNAs as biomarkers of platelet function since the detection of pathogenic situations or response to therapy using these noncoding RNAs is getting increasing interest in disease management. Finally, this chapter describes the participation of platelets in cellular interplay, since extracellular vesicles have been demonstrated to have the ability to deliver microRNAs to others cells, modulating their function through intercellular communication, redefining the extracellular vesicles from the so-called “platelet dust” to become mediators of intercellular communication.

Long noncoding RNA MIAT promotes the progression of acute myeloid leukemia by negatively regulating miR-495. Leuk Res 2019; 87:106265.

Abstract
Acute myeloid leukemia (AML) is a malignant myeloid hematopoietic stem and progenitor cell disease. Studies have shown that the long noncoding RNA (lncRNA) myocardial infarction associated transcript (MIAT) is abundantly expressed in multiple human solid tumors. However, the expression and role of MIAT in AML has not been explored previously. In this study, we find that MIAT is overexpressed in AML patient specimens and AML cell lines. Importantly, upregulation of MIAT is closely related with poor clinical outcome. Further investigations reveal that knockdown of MIAT inhibits the colony formation and proliferation, meanwhile, accelerates the apoptosis of AML cells in vitro. Consistently, MIAT knockdown slows AML progression in immunodeficient mice. Mechanistically, we confirm that MIAT can function as a sponge to inhibit microRNA-495 (miR-495), a tumor suppressor, in AML cells. Collectively, our results demonstrate that MIAT is involved in promoting the progression of AML, at least partly, through negative regulation of miR-495, and therefore provide a promising target for treatment of AML.

Abstract
BACKGROUND Azacitidine (AZA) is a nucleoside analog used for treatment of myelodysplasia and the prediction of AZA responsiveness is important for the therapy management. METHODS Using microarrays and reverse-transcription quantitative-PCR, we analyzed microRNA (miRNA) expression in bone marrow CD34+ cells of 27 patients with higher-risk myelodysplastic syndromes or acute myeloid leukemia with myelodysplasia-related changes before and during AZA treatment. RESULTS At baseline, we found that future overall response rate was significantly higher in patients with upregulated miR-17-3p and downregulated miR-100-5p and miR-133b. Importantly, the high level of miR-100-5p at baseline was associated with shorter overall survival (HR = 4.066, P= 0.008). After AZA treatment, we observed deregulation of 30 miRNAs in responders (including downregulation of miR-10b-5p, miR-15a-5p/b-5p, miR-24-3p, and miR-148b-3p), while their levels remained unchanged in non-responders. CONCLUSIONS Our study demonstrates that responders and non-responders have distinct miRNA patterns and that the level of specific miRNAs before therapy may predict the efficacy of AZA treatment.

Abstract
miR-1 and miR-133 are clustered on the same chromosomal loci and are transcribed together as a single transcript that is positively regulated by ecotropic virus integration site-1 (EVI1). Previously, we described how miR-133 has anti-tumorigenic potential through repression of EVI1 expression. It has also been reported that miR-1 is oncogenic in the case of acute myeloid leukemia (AML). Here, we show that expression of miR-1 and miR-133, which have distinct functions, is differentially regulated between AML cell lines. Interestingly, the expression of miR-1 and EVI1, which binds to the promoter of the miR-1/miR-133 cluster, is correlative. The expression levels of TDP-43, an RNA-binding protein that has been reported to increase the expression, but inhibits the activity, of miR-1, were not correlated with expression levels of miR-1 in AML cells. Taken together, our observations raise the possibility that the balance of polycistronic miRNAs is regulated post-transcriptionally in a hierarchical manner possibly involving EVI1, suggesting that the deregulation of this balance may play some role in AML cells with high EVI1 expression.

Abstract
Background ETS2 is a downstream effector of the RAS/RAF/ERK pathway, which plays a critical role in the development of malignant tumor. However, the clinical impact of ETS2 expression in AML remains unknown. Methods In this study, we evaluated the prognostic significance of ETS2 expression using two relatively large cohorts of AML patients. Results In the first cohort, compared to low expression of ETS2 (ETS2low), high expression of ETS2 (ETS2high) showed significant shorter OS, EFS and RFS in the current treatments including the allogeneic HCT group (n = 72) and the chemotherapy group (n = 100). Notably, among ETS2high patients, those received allogeneic HCT had longer OS, EFS and RFS than those with chemotherapy alone (allogeneic HCT, n = 39 vs. chemotherapy, n = 47), but treatment modules play insignificant role in the survival of ETS2low patients (allogeneic HCT, n = 33 vs. chemotherapy, n = 53). Moreover, gene/microRNA expression data provides insights into the biological changes associated with varying ETS2 expression levels in AML. The prognostic value of ETS2 was further validated in the second AML cohort (n = 329). Conclusions Our results indicate that ETS2high is a poor prognostic factor in AML and may guide treatment decisions towards allogeneic HCT.

Abstract
MicroRNAs (miRs) have been found to play important roles in tumorigenesis, apoptosis, metastasis, and drug resistance in cancer. Among a number of miRs, miR-1 was shown to be predominantly downregulated in almost all examined human cancers. As a tumor suppressor miR involved in post-transcriptional regulation of crucial tumor associated gene expression, miR-1 represents a promising target for anticancer therapy. Re-expression of miR-1 can suppress cancer cell proliferation, promote apoptosis, and reverse drug resistance in cancers both in vitro and in vivo. Recently, the regulatory mechanisms of miR-1 expression have been studied in various cancers in different model systems. In this review, we summarize the mechanisms of miR-1 expression through epigenetic, transcriptional, and post-transcriptional regulation. These regulatory mechanisms of miR-1 expression could help us to understand the functions of altered miR-1 expression and provide valuable insights for further investigations into miR-1 based cancer therapy.

Abstract
Gastric cancer (GC) remains the third most common cause of cancer deaths worldwide and carries a high rate of metastatic risk contributing to the main cause of treatment failure. An accumulation of data has resulted in a better understanding of the molecular network of GC, however, gaps still exist between the unique bio-resources and clinical application. MicroRNAs are an important part of non-coding RNAs and behave as major regulators of tumour biology, alongside their well-known roles as intrinsic factors of gene expression in cellular processes, via their post-transcriptional regulation of components of signalling pathways in a coordinated manner. Deregulation of the miR-1, -133 and -206 family plays a key role in tumorigenesis, progression, invasion and metastasis. This review aims to provide a summary of recent findings on the miR-1, -133 and -206 family in GC and how this knowledge might be exploited for the development of future miRNA-based therapies for the treatment of GC.

Abstract
Breast cancer is the second leading cause of cancer death in women and the presence of metastasis significantly decreases survival. MicroRNAs are involved in tumor progression and the metastatic spreading of breast cancer. Here, we reported that a microRNA, mmu-miR-1894, significantly decreased the lung metastasis of 4TO7 mouse breast cancer cells by 86.7% in mouse models. Mmu-miR-1894-3p was the functional mature form of miR-1894 and significantly decreased the lung metastasis of 4TO7 cells by 90.8% in mouse models. A dual-luciferase reporter assay indicated that mmu-miR-1894-3p directly targeted the tripartite motif containing 46 (Trim46) 3'-untranslated region (UTR) and downregulated the expression of Trim46 in 4TO7 cells. Consistent with the effect of mmu-miR-1894-3p, knockdown of Trim46 inhibited the experimental lung metastasis of 4TO7 cells. Moreover, knockdown of human Trim46 also prohibited the cell proliferation, migration and wound healing of MBA-MD-231 human breast cancer cells. These results suggested that the effect of knockdown of Trim46 alone was sufficient to recapitulate the effect of mmu-miR-1894 on the metastasis of the breast cancer cells in mouse and that Trim46 was involved in the proliferation and migration of mouse and human breast cancer cells.

Abstract
Neurotensin (NT) triggers signaling in human colonic epithelial cells by activating the G protein-coupled receptor, the neurotensin receptor 1 (NTR1). Activated NTR1 traffics from the plasma membrane to early endosomes, and then recycles. Although sustained NT/NTR1 signaling requires efficient NTR1 recycling, little is known about the regulation of NTR1 recycling. We recently showed that NT/NTR1 signaling increases expression of miR-133α. Herein, we studied the mechanism of NT-regulated miR-133α expression and examined the role of miR-133α in intracellular NTR1 trafficking in human NCM460 colonocytes. We found that NT-induced miR-133α upregulation involves the negative transcription regulator, zinc finger E-box binding homeobox 1. Silencing of miR-133α or overexpression of aftiphilin (AFTPH), a binding target of miR-133α, attenuated NTR1 trafficking to plasma membrane in human colonocytes, without affecting NTR1 internalization. We localized AFTPH to early endosomes and the trans-Golgi network (TGN) in unstimulated human colonic epithelial cells. AFTPH overexpression reduced NTR1 localization in early endosomes and increased expression of proteins related to endosomes and the TGN trafficking pathway. AFTPH overexpression and de-acidification of intracellular vesicles increased NTR1 expression. Our results suggest a novel mechanism of GPCR trafficking in human colonic epithelial cells by which a microRNA, miR-133α regulates NTR1 trafficking through its downstream target AFTPH.

miR-133 regulates Evi1 expression in AML cells as a potential therapeutic target. Sci Rep 2016; 6:19204.

Abstract
The Ecotropic viral integration site 1 (Evi1) is a zinc finger transcription factor, which is located on chromosome 3q26, over-expression in some acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Elevated Evi1 expression in AML is associated with unfavorable prognosis. Therefore, Evi1 is one of the strong candidate in molecular target therapy for the leukemia. MicroRNAs (miRNAs) are small non-coding RNAs, vital to many cell functions that negatively regulate gene expression by translation or inducing sequence-specific degradation of target mRNAs. As a novel biologics, miRNAs is a promising therapeutic target due to its low toxicity and low cost. We screened miRNAs which down-regulate Evi1. miR-133 was identified to directly bind to Evi1 to regulate it. miR-133 increases drug sensitivity specifically in Evi1 expressing leukemic cells, but not in Evi1-non-expressing cells The results suggest that miR-133 can be promising therapeutic target for the Evi1 dysregulated poor prognostic leukemia.

Abstract
Metastatic breast cancer remains a highly lethal disease, and it is very important to evaluate the biomarkers associated with the distant metastasis. MicroRNA (miRNA) are small non‐protein coding RNA that regulate various cellular functions. Recent investigations have demonstrated the importance of some miRNA in breast cancer, but the significance of the great majority of miRNA remains largely unclear in breast cancer metastasis. Therefore, in this study, we first examined expression profiles of miRNA in stage IV breast carcinoma tissues, comparing stage I–III cases by miRNA PCR array, and identified miR‐1 as the miRNA which was the most associated with the distant metastasis. However, miR‐1 has not yet been examined in breast carcinoma tissue, and its significance remains unknown. Therefore, we further examined miR‐1 expression in breast carcinoma using in situ hybridization (ISH). miR‐1 was localized in carcinoma cells in 20% of breast carcinoma cases, but it was negligible in non‐neoplastic mammary glands or stroma. miR‐1 ISH status was significantly associated with stage, pathological T factor, lymph node metastasis, distant metastasis, histological grade, estrogen receptor, progesterone receptor and Ki‐67 in breast carcinoma. Moreover, the miR‐1 status was demonstrated using multivariate analysis as an independent worse prognostic factor for both disease‐free and breast cancer‐specific survival. These findings suggest that abnormal miR‐1 expression is associated with an aggressive phenotype of breast carcinoma and that miR‐1 status is a potent prognostic factor in human breast cancer patients.

Abstract
MicroRNAs are small non-coding RNAs that participate in different biological processes, providing subtle combinational regulation of cellular pathways, often by regulating components of signalling pathways. Aberrant expression of miRNAs is an important factor in the development and progression of disease. The canonical myomiRs (miR-1, -133 and -206) are central to the development and health of mammalian skeletal and cardiac muscles, but new findings show they have regulatory roles in the development of other mammalian non-muscle tissues, including nerve, brain structures, adipose and some specialised immunological cells. Moreover, the deregulation of myomiR expression is associated with a variety of different cancers, where typically they have tumor suppressor functions, although examples of an oncogenic role illustrate their diverse function in different cell environments. This review examines the involvement of the related myomiRs at the crossroads between cell development/tissue regeneration/tissue inflammation responses, and cancer development.

EVI1 promotes tumor growth via transcriptional repression of MS4A3. J Hematol Oncol 2015; 8:28.

Abstract
Background The transcription factor Ecotropic Virus Integration site 1 (EVI1) regulates cellular proliferation, differentiation, and apoptosis, and its overexpression contributes to an aggressive course of disease in myeloid leukemias and other malignancies. Notwithstanding, knowledge about the target genes mediating its biological and pathological functions remains limited. We therefore aimed to identify and characterize novel EVI1 target genes in human myeloid cells. Methods U937T_EVI1, a human myeloid cell line expressing EVI1 in a tetracycline regulable manner, was subjected to gene expression profiling. qRT-PCR was used to confirm the regulation of membrane-spanning-4-domains subfamily-A member-3 (MS4A3) by EVI1. Reporter constructs containing various parts of the MS4A3 upstream region were employed in luciferase assays, and binding of EVI1 to the MS4A3 promoter was investigated by chromatin immunoprecipitation. U937 derivative cell lines experimentally expressing EVI1 and/or MS4A3 were generated by retroviral transduction, and tested for their tumorigenicity by subcutaneous injection into severe combined immunodeficient mice. Results Gene expression microarray analysis identified 27 unique genes that were up-regulated, and 29 unique genes that were down-regulated, in response to EVI1 induction in the human myeloid cell line U937T. The most strongly repressed gene was MS4A3, and its down-regulation by EVI1 was confirmed by qRT-PCR in additional, independent experimental model systems. MS4A3 mRNA levels were also negatively correlated with those of EVI1 in several published AML data sets. Reporter gene assays and chromatin immunoprecipitation showed that EVI1 regulated MS4A3 via direct binding to a promoter proximal region. Experimental re-expression of MS4A3 in an EVI1 overexpressing cell line counteracted the tumor promoting effect of EVI1 in a murine xenograft model by increasing the rate of apoptosis. Conclusions Our data reveal MS4A3 as a novel direct target of EVI1 in human myeloid cells, and show that its repression plays a role in EVI1 mediated tumor aggressiveness.

Abstract
Human ectopic viral integration site 1 (EVI1) is an oncogenic transcription factor known to play a critical role in many aggressive forms of cancer. Its selective modulation is thought to alter the cancer-specific gene regulatory networks. Pyrrole-imidazole polyamides (PIPs) are a class of small DNA binders that can be designed to target any destined DNA sequence. Herein, we report a sequence-specific pyrrole-imidazole polyamide, PIP1, which can target specific base pairs of the REL/ELK1 binding site in the EVI1 minimal promoter. The designed PIP1 significantly inhibited EVI1 in MDA-MB-231 cells. Whole-transcriptome analysis confirmed that PIP1 affected a fraction of EVI1-mediated gene regulation. In vitro assays suggested that this polyamide can also effectively inhibit breast cancer cell migration. Taken together, these results suggest that EVI1-targeted PIP1 is an effective transcriptional regulator in cancer cells.

Abstract
Despite frequent KRAS mutation, the early molecular mechanisms of pancreatic ductal adenocarcinoma (PDAC) development have not been fully elucidated. By tracking a potential regulator of another feature of PDAC precursors, acquisition of foregut or gastric epithelial gene signature, we herein report that aberrant overexpression of ecotropic viral integration site 1 (EVI1) oncoprotein, which is usually absent in normal pancreatic duct, is a widespread marker across the full spectrum of human PDAC precursors and PDAC. In pancreatic cancer cells, EVI1 depletion caused remarkable inhibition of cell growth and migration, indicating its oncogenic roles. Importantly, we found that EVI1 upregulated KRAS expression through suppression of a potent KRAS suppressor, miR-96, in pancreatic cancer cells. Collectively, the present findings suggest that EVI1 overexpression and KRAS mutation converge on activation of the KRAS pathway in early phases of pancreatic carcinogenesis and propose EVI1 and/or miR-96 as early markers and therapeutic targets in this dismal disease.

Abstract
Amplification of 3q26.2, found in many cancer lineages, is a frequent and early event in ovarian cancer. We previously defined the most frequent region of copy number increase at 3q26.2 to EVI1 (ecotropic viral integration site-1) and MDS1 (myelodysplastic syndrome 1) (aka MECOM), an observation recently confirmed by the cancer genome atlas (TCGA). MECOM is increased at the DNA, RNA, and protein level and likely contributes to patient outcome. Herein, we report that EVI1 is aberrantly spliced, generating multiple variants including a Del(190-515) variant (equivalent to previously reported) expressed in >90% of advanced stage serous epithelial ovarian cancers. Although EVI1(Del190-515) lacks ∼70% of exon 7, it binds CtBP1 as well as SMAD3, important mediators of TGFβ signaling, similar to wild type EVI1. This contrasts with EVI1 1-268 which failed to interact with CtBP1. Interestingly, the EVI1(Del190-515) splice variant preferentially localizes to PML nuclear bodies compared to wild type and EVI1(Del427-515). While wild type EVI1 efficiently repressed TGFβ-mediated AP-1 (activator protein-1) and plasminogen activator inhibitor-1 (PAI-1) promoters, EVI1(Del190-515) elicited a slight increase in both promoter activities. Expression of EVI1 and EVI1(Del427-515) (but not EVI1(Del190-515)) in OVCAR8 ovarian cancer cells increased cyclin E1 LMW expression and cell cycle progression. Furthermore, knockdown of specific EVI1 splice variants (both MDS1/EVI1 and EVI1(Del190-515)) markedly increased claudin-1 mRNA and protein expression in HEY ovarian and MDA-MB-231 breast cancer cells. Changes in claudin-1 were associated with alterations in specific epithelial-mesenchymal transition markers concurrent with reduced migratory potential. Collectively, EVI1 is frequently aberrantly spliced in ovarian cancer with specific forms eliciting altered functions which could potentially contribute to ovarian cancer pathophysiology.

Abstract
Activation of NRas signaling is frequently found in human myeloid leukemia and can be induced by activating mutations as well as by mutations in receptors or signaling molecules upstream of NRas. To study NRas-induced leukemogenesis, we retrovirally overexpressed wild-type NRas in a murine bone marrow transplantation (BMT) model in C57BL/6J mice. Overexpression of wild-type NRas caused myelomonocytic leukemias ∼3 months after BMT in the majority of mice. A subset of mice (30%) developed malignant histiocytosis similar to mice that received mutationally activated NRas(G12D)-expressing bone marrow. Aberrant Ras signaling was demonstrated in cells expressing mutationally active or wild-type NRas, as increased activation of Erk and Akt was observed in both models. However, more NRas(G12D) were found to be in the activated, GTP-bound state in comparison with wild-type NRas. Consistent with observations reported for primary human myelomonocytic leukemia cells, Stat5 activation was also detected in murine leukemic cells. Furthermore, clonal evolution was detected in NRas wild-type-induced leukemias, including expansion of clones containing activating vector insertions in known oncogenes, such as Evi1 and Prdm16. In vitro cooperation of NRas and Evi1 improved long-term expansion of primary murine bone marrow cells. Evi1-positive cells upregulated Bcl-2 and may, therefore, provide anti-apoptotic signals that collaborate with the NRas-induced proliferative effects. As activation of Evi1 has been shown to coincide with NRAS mutations in human acute myeloid leukemia, our murine model recapitulates crucial events in human leukemogenesis.

Abstract
MicroRNAs (miRNAs) are endogenous short non-coding RNA molecules that regulate gene expression by repressing translation or cleaving RNA transcripts in a sequence-specific manner. A growing body of evidence suggests that miRNAs are aberrantly expressed in many human cancers and that they play significant roles in the initiation, development and metastasis of human cancers. Genome-wide miRNA expression signatures provide information on the aberrant expression of miRNAs in cancers rapidly and precisely. Recently, studies from our group and others revealed that microRNA-1 (miR-1), microRNA-133a (miR-133a), microRNA-133b (miR-133b) and microRNA-206 (miR-206) are frequently downregulated in various types of cancers. Interestingly, miR-1-1/miR-133a-2, miR-1-2/miR-133a-1, and miR-206/miR-133b form homologous clusters in three different chromosomal regions of the human genome – 20q13.33, 18q11.2 and 6p12.2, respectively. Here we review recent findings on the aberrant expression and functional significance of the miR-1/miR-133a and miR-206/miR-133b clusters in human cancers.

Abstract
Recent studies have demonstrated the significance of the leukemia oncogene Evi1 as the regulator of hematopoietic stem cells and marker of poor clinical outcomes in myeloid malignancies. Evi1-mediated leukemogenic activities include a wide array of functions such as the induction of epigenetic modifications, transcriptional control, and regulation of signaling pathways. We have recently succeeded in comprehensively elucidating the oncogenic function of Evi1 in a model of the polycomb-Evi1-PTEN/AKT/mTOR axis. These results may provide us with novel therapeutic approaches to conquer the poor prognosis associated with Evi1-activated leukemia or other solid tumors with high Evi1 expression. Here, we review the current understanding of the role of Evi1 in controlling the development of leukemia and highlight potential modalities for targeting factors involved in Evi1-regulated signaling.

Abstract
Micro RNAs (miRNAs) have emerged as potentially useful and specific agents to regulate transcriptional control of many cellular genes. There is a real prospect that miRNA and other short-length RNA reagents could be useful in a therapeutic setting. Here we outline the control of miRNAs in acute myeloid leukaemia (AML) subtype of human leukaemia, and ask whether miRNA could be important either in the generation of an AML phenotype, or as a variety of agents to combat the disease in the clinic. The use of miRNAs as potential biomarkers of aberrant signalling pathways involved in AML oncogenesis is also discussed.

miRNA-1 targets fibronectin1 and suppresses the migration and invasion of the HEp2 laryngeal squamous carcinoma cell line. FEBS Lett 2011; 585:3263-9. [PMID: 21924268 DOI: 10.1016/j.febslet.2011.08.052] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2011] [Revised: 08/31/2011] [Accepted: 08/31/2011] [Indexed: 11/21/2022]
Abstract
MicroRNAs (miRNAs) are an evolutionarily conserved class of endogenous, non-coding RNAs that modulate gene expression at the post-transcriptional level and are involved in tumorigenesis. In this study, we demonstrate that miR-1 suppresses the potential for growth, migration and invasion in the HEp2 cell line. Furthermore, we validate that FN1 is a direct target gene for miR-1 via fluorescent reporter assay and is negatively regulated by miR-1. Moreover, the knockdown of FN1 has the same phenotypic effects as the overexpression of miR-1. Taken together, our results provide evidence that miR-1 may play a role as a tumor suppressor gene in laryngeal carcinoma.
