Abstract
OBJECTIVES Infertility is inability to conceive after 12 months of regular unprotected sex. MiRNA expression changes can serve as potential biomarkers for infertility in males due to impaired spermatogenesis. This research was conducted to measure the expression level of miR-211 in plasma samples as a factor identifying infertility in comparison with the control group. METHODS In this study, blood plasma were taken from the infertile men (n = 103) nonobstructive azoospermia (NOA) or severe oligozoospermia (SO) and the control group (n = 121). The expression of circulating miR-211 in plasma was assessed by qRT-PCR. A relative quantification strategy was adopted using the 2-ΔΔCT method to calculate the target miR-211 expression level in both study groups. RESULTS Plasma miR-211 levels were significantly lower in infertile men compared to the control group (0.544 ± 0.028 and 1.203 ± 0.035, respectively, p < 0.001). Pearson's correlation analysis showed that miR-211 expression level has a positive and significant correlation with sperm parameters, including sperm concentration, sperm total motility, progressive motility, and normal morphology (p < 0.001). CONCLUSIONS Decreased expression of miR-211 in blood plasma seems to be associated with male infertility. This experiment showed that miR-211 can be considered as a biomarker for evaluation, diagnosis, and confirmation of the results of semen analysis in male infertility.

Abstract
PURPOSE Leptomeningeal metastasis (LM) is a complication of surgery for brain metastasis and is a risk factor of poor prognosis. The risk of LM is particularly high after surgery for a breast cancer metastasis to the brain. If the risk of LM after surgical resection for a brain metastasis were predictable, appropriate adjuvant therapy could be administered to individual patients to improve their prognosis. The present study aimed to reveal the genetic characteristics of brain metastases as means of predicting LM in breast cancer patients. METHODS Ten patients with brain metastases of breast cancer presented LM after surgical resection were analyzed by whole-exome sequencing. RESULTS A chromodomain-helicase-DNA-binding protein 5 (CHD5) gene alteration was detected in nine cases (90%), including a nonsynonymous variant in four cases and copy number deletion in five cases. CHD5 protein expression was lost in nine cases and had decreased in one case. The frequency of CHD5 gene alteration in brain metastases with LM was significantly higher than in primary breast cancer (2.3%) or in brain metastases of breast cancer (0%) (p < 0.0001). CONCLUSIONS These results suggested that the CHD5 gene alteration was associated with LM after surgical resection of breast cancer brain metastases. Searching for the gene alteration might predict the LM risk after surgical resection.

Abstract
CHD5, a tumor suppressor at 1p36, is frequently lost or silenced in poor prognosis neuroblastoma (NB) and many adult cancers. The role of CHD5 in metastasis is unknown. We confirm that low expression of CHD5 is associated with stage 4 NB. Forced expression of CHD5 in NB cell lines with 1p loss inhibited key aspects of the metastatic cascade in vitro: anchorage-independent growth, migration, and invasion. In vivo, formation of bone marrow and liver metastases developing from intravenously injected NB cells was delayed and decreased by forced CHD5 expression. Genome-wide mRNA sequencing revealed reduction of genes and gene sets associated with metastasis when CHD5 was overexpressed. Known metastasis-suppressing genes preferentially upregulated in CHD5-overexpressing NB cells included PLCL1. In patient NB, low expression of PLCL1was associated with metastatic disease and poor survival. Knockdown of PLCL1 and of p53 in IMR5 NB cells overexpressing CHD5 reversed CHD5-induced inhibition of invasion and migration in vitro. In summary, CHD5 is a metastasis suppressor in NB.

Abstract
MYCN Proto-Oncogene, BHLH Transcription Factor (MYCN) has been one of the most studied genes in neuroblastoma. It is known for its oncogenetic mechanisms, as well as its role in the prognosis of the disease and it is considered one of the prominent targets for neuroblastoma therapy. In the present work, we attempted to review the literature, on the relation between MYCN and neuroblastoma from all possible mechanistic sites. We have searched the literature for the role of MYCN in neuroblastoma based on the following topics: the references of MYCN in the literature, the gene's anatomy, along with its transcripts, the protein's anatomy, the epigenetic mechanisms regulating MYCN expression and function, as well as MYCN amplification. MYCN plays a significant role in neuroblastoma biology. Its functions and properties range from the forming of G-quadraplexes, to the interaction with miRNAs, as well as the regulation of gene methylation and histone acetylation and deacetylation. Although MYCN is one of the most primary genes studied in neuroblastoma, there is still a lot to be learned. Our knowledge on the exact mechanisms of MYCN amplification, etiology and potential interventions is still limited. The knowledge on the molecular mechanisms of MYCN in neuroblastoma, could have potential prognostic and therapeutic advantages.

Abstract
The establishment and maintenance of genome packaging into chromatin contribute to define specific cellular identity and function. Dynamic regulation of chromatin organization and nucleosome positioning are critical to all DNA transactions-in particular, the regulation of gene expression-and involve the cooperative action of sequence-specific DNA-binding factors, histone modifying enzymes, and remodelers. Remodelers are molecular machines that generate various chromatin landscapes, adjust nucleosome positioning, and alter DNA accessibility by using ATP binding and hydrolysis to perform DNA translocation, which is highly regulated through sophisticated structural and functional conversations with nucleosomes. In this review, I first present the functional and structural diversity of remodelers, while emphasizing the basic mechanism of DNA translocation, the common regulatory aspects, and the hand-in-hand progressive increase in complexity of the regulatory conversations between remodelers and nucleosomes that accompanies the increase in challenges of remodeling processes. Next, I examine how, through nucleosome positioning, remodelers guide the regulation of gene expression. Finally, I explore various aspects of how alterations/mutations in remodelers introduce dissonance into the conversations between remodelers and nucleosomes, modify chromatin organization, and contribute to oncogenesis.

Abstract
Abdominal tumors (AT) in children account for approximately 17% of all pediatric solid tumor cases, and frequently exhibit embryonal histological features that differentiate them from adult cancers. Current molecular approaches have greatly improved the understanding of the distinctive pathology of each tumor type and enabled the characterization of novel tumor biomarkers. As seen in abdominal adult tumors, microRNAs (miRNAs) have been increasingly implicated in either the initiation or progression of childhood cancer. Moreover, besides predicting patient prognosis, they represent valuable diagnostic tools that may also assist the surveillance of tumor behavior and treatment response, as well as the identification of the primary metastatic sites. Thus, the present study was undertaken to compile up-to-date information regarding the role of dysregulated miRNAs in the most common histological variants of AT, including neuroblastoma, nephroblastoma, hepatoblastoma, hepatocarcinoma, and adrenal tumors. Additionally, the clinical implications of dysregulated miRNAs as potential diagnostic tools or indicators of prognosis were evaluated.

Abstract
Chromodomain helicase DNA-binding 5 (CHD5), which is a member of the CHD family, has been identified as a tumor suppressor gene in a variety of malignancies. The aim of the current study was to clarify the clinical significance of CHD5 expression in gastric cancer. CHD5 expression was evaluated using immunohistochemistry (IHC) in 154 specimens resected from patients with gastric cancer from January 2011 to December 2013, and assessed its relationships with clinicopathological characteristics and survival. In vitro cell proliferation, invasion, and migration assays and western blotting analysis were performed to clarify the role of CHD5 in human gastric cancer cell lines. Of a total of 154 patients, 57 (37.0%) exhibited low CHD5 expression, which was significantly associated with positive lymphatic invasion (P=0.032), advanced pT status (P=0.011), and advanced pStage (P=0.014). Overall survival (OS) in patients with low CHD5 expression was significantly worse compared with patients with high CHD5 expression (hazard ratio, 1.96; 95% confidence interval, 1.09-3.45; log-rank P=0.023). Cox multivariate analysis for OS revealed that CHD5 expression was an independent prognostic factor with age and pN status. In vitro, the upregulation of CHD5 in gastric cancer cells with low CHD5 expression significantly decreased cell proliferation, migration and invasion. CHD5 was associated with the regulation of multiple cancer-related targets, including p53 and enhancer of zeste homolog 2 (EZH2) in western blotting analysis. In conclusion, since CHD5 regulated multiple cancer-related targets, its expression may be a useful prognostic biomarker in patients with gastric cancer.

Abstract
Objectives This study aims to evaluate the plasma expression of microribonucleic acids (miRNAs) that may be associated with the pathogenesis of familial Mediterranean fever (FMF). Patients and methods Thirty patients with FMF (18 males, 12 females; mean age 9.1±4.7 years; range, 3 to 15.5 years) and 30 age- and sex-matched healthy children (18 males, 12 females; mean age 9.5±4.6 years; range, 4 to 16.5 years) were included in this study. The plasma levels of four candidate miRNAs (miRNA-16, miRNA-155, miRNA-204 and miRNA-451) were measured in all subjects. The plasma levels of miRNAs were analyzed with real- time polymerase chain reaction in attack and remission periods of patients and healthy controls (HCs). Results Plasma miRNA-204 levels of FMF patients were decreased 6.5 fold in remission period compared to HCs (p<0.001). This decrease was more prominent in M694V mutation carriers. Plasma miRNA-155 levels of FMF patients were lower in remission period (p=0.03). Conclusion Our findings showed significant alterations in the plasma expression of miRNA-155 and miRNA-204 in FMF patients compared to HCs. Our data suggest that miRNA-155 and miRNA-204 may be related to the pathogenesis of FMF. Further comprehensive and functional researches may help to clarify the role of miRNAs in FMF and elucidate the pathogenesis of the disease.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of childhood, yet its etiology is unknown. It is known that microribonucleic acids (miRNAs) play a role in immunoregulation. We aimed to evaluate the plasma expression of some candidate miRNAs that are associated with the pathogenesis of autoimmunity. Thirty-one patients diagnosed with JIA and age-sex-matched 31 healthy children were enrolled for the study. The plasma levels of four candidate miRNAs (miRNA-16, miRNA-155, miRNA-204, and miRNA-451), which are known to be associated with autoimmunity, were examined in all the subjects. The plasma levels of miRNAs were measured with real-time PCR in the patients in active and inactive periods and in the healthy controls. The groups were compared with each other. The plasma miRNA-155 levels were found to increase in the JIA patients compared to the healthy controls, and it was statistically more significant in the inactive period. We found that the JIA patients had the higher levels of miRNA-16 and the lower levels of miRNA-204/miRNA-451 expressions compare with the control group, but there was no statistically significant difference. A statistically significant decrease in the plasma levels of miRNA-204 was found in the patients that were in inactive disease with only methotrexate therapy. The plasma miRNA expressions were compared in the JIA subtypes, and it was observed that miRNA-204 levels were higher in polyarticular JIA and miRNA-451 levels were higher in enthesitis-related arthritis without statistical significance. The significant alterations in the plasma expression of miRNA-155 and miRNA-204 suggest to us that these molecules may be related to the pathogenesis of JIA. More comprehensive and functional researches about the role of these molecules are needed in this regard.

Abstract
In recent years, technological advances have enabled a detailed landscaping of the epigenome and the mechanisms of epigenetic regulation that drive normal cell function, development and cancer. Rather than merely a structural entity to support genome compaction, we now look at chromatin as a very dynamic and essential constellation that is actively participating in the tight orchestration of transcriptional regulation as well as DNA replication and repair. The unique feature of chromatin flexibility enabling fast switches towards more or less restricted epigenetic cellular states is, not surprisingly, intimately connected to cancer development and treatment resistance, and the central role of epigenetic alterations in cancer is illustrated by the finding that up to 50% of all mutations across cancer entities affect proteins controlling the chromatin status. We summarize recent insights into epigenetic rewiring underlying neuroblastoma (NB) tumor formation ranging from changes in DNA methylation patterns and mutations in epigenetic regulators to global effects on transcriptional regulatory circuits that involve key players in NB oncogenesis. Insights into the disruption of the homeostatic epigenetic balance contributing to developmental arrest of sympathetic progenitor cells and subsequent NB oncogenesis are rapidly growing and will be exploited towards the development of novel therapeutic strategies to increase current survival rates of patients with high-risk NB.

Abstract
Previous studies showed that the low expressions of chromodomain-helicase-DNA-binding protein 5 (CHD5) were intensively associated with deteriorative biologic and clinical characteristics as well as outcomes in many tumors. The aim of this study is to determine whether CHD5 single nucleotide polymorphisms (SNPs) contribute to the prognosis of hepatocellular carcima (HCC). The SNPs were selected according to their linkage disequilibrium (LD) in the targeted next-generation sequencing (NGS) and then genotyped with TaqMan probers. We revealed a rare haplotype AG in CHD5 (SNPs: rs12564469-rs9434711) was markedly associated with HCC prognosis. The univariate and multivariate regression analyses revealed the patients with worse overall survival time were those with tumor metastasis and haplotype AG, as well as cirrhosis, poor differentiation and IV-TNM stage. Based on the available public databases, we discovered the significant association between haplotype AG and CHD5 mRNA expressions only existed in Chinese. These data proposed that the potentially genetic haplotype might functionally contribute to HCC prognosis and CHD5 mRNA expressions.

Cancer Cell Int 2017; 17:81.

Abstract
Background/aims ErbB3 is an oncogene which has proliferation and metastasis promotion effects by several signaling pathways. However, the individual expression difference regulated by miRNA was almost still unknown. We focused on the miRNAs associated SNPs in the 3′-UTR of ErbB3 to investigate the further relationship of the SNPs with miRNAs among Chinese gastric cancer (GC) patients. Methods We performed case–control study including 851 GC patients and 799 cancer-free controls. Genotyping, real-time PCR assay, cell transfection, the dual luciferase reporter assay, western-blot, cell proliferation and trans-well based cell invasion assay were used to investigate the effects of the SNP on ErbB3 expression. Moreover, a 5-years-overall survival and relapse free survival were investigated between different genotypes. Results We found that patients suffering from Helicobacter pylori (Hp.) infection indicated to be the susceptible population by comparing with controls. Besides, SNP rs3202538 (G/T) in ErbB3 3′-UTR was involved in the occurrence of GC by acting as tumor risk factors. SNP rs3202538 (G/T) could be regulated by both miR-204 and miR-211 which caused an upregulation of ErbB3 in patients. Furthermore, the carriers of T genotype was related to the significantly high expression of ErbB3, and to big tumor size, poor differentiation as well as the high probability of metastasis. Both miR-211 and miR-204 can significantly decrease cell proliferation, metastasis as well as downstream AKT activation through G but not T allele of ErbB3 3′UTR. Moreover, the SNP of G/T was associated with shorter survival of post-surgery GC patients with 5 years of follow up study. Conclusion In conclusion, our findings have shown that the SNP rs3202538 (G/T) in ErbB3 3′-UTR acted as promotion factors in the GC development through disrupting the regulatory role of miR-204 and miR-211 in ErbB3 expression.

A genome-wide microRNA profiling indicates miR-424-5p and miR-503-5p as regulators of ALK expression in neuroblastoma. Oncotarget 2017; 8:56518-56532. [PMID: 28915608 PMCID: PMC5593579 DOI: 10.18632/oncotarget.17033] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 03/29/2017] [Indexed: 12/30/2022] Open
Abstract
The discovery of missense mutations of ALK gene identified this receptor tyrosine kinase as a therapeutic target in neuroblastoma (NB). Moreover, a high level of ALK protein has been associated with metastatic NB cases and with a worse prognosis, suggesting that also ALK overexpression is involved in NB tumorigenesis. Since miRNAs play key roles in the regulation of gene expression we aimed at identifying those miRNAs that can regulate ALK in NB. We therefore analyzed the genome-wide expression profile of miRNAs in two sample sets of 16 NB cell lines and 22 NB samples by using miRNA microarrays. Both sample sets were then divided into two subgroups showing high (ALK+) or low/absent (ALK-) expression of ALK. Results showed a down-regulation of 30 and 23 miRNAs (p-value <0.05) in the ALK+ group in NB cell lines and samples, respectively. Validation analysis indicated that miR-424-5p and miR-503-5p, belonging to the same cluster, were differentially expressed in both NB cell lines and tumor samples. Although only miR-424-5p showed a direct binding to ALK 3′-UTR, both miRNAs led to a remarkable decreasing of ALK protein as well as to the inhibition of cell viability in ALK+ NB cell lines. In conclusion, our data indicate that both miR-424-5p and miR-503-5p are involved in regulating ALK expression in NB, either by directly targeting ALK receptor or indirectly, and may thus serve as potential therapeutic tools in ALK dependent NBs.

Abstract
Lung cancer is one of the deadliest types of cancers and genetic and epigenetic alterations play major roles in its development. Chromodomain (CHD) protein family acts in chromatin organization, regulation of transcription and also genomic stability and cancer prevention. Although CHD5, a member of this family was shown to contribute to major cellular events and functions as a tumor suppressor gene in various types of cancer, it is not clear whether CHD5 plays a role in lung carcinogenesis. The aim of this study was to investigate the possible role of CHD5 in progression of non-small cell lung cancer (NSCLC). Expression levels of CHD5 gene in 59 tumor and corresponding non-cancerous lung tissue samples were analyzed by qRT-PCR and the methylation status of the promoter region was investigated by methylation specific PCR (MS-PCR). The Akt phosphorylation levels were investigated by Western Blot (WB). CHD5 was down-regulated in 17 (39.5%) and up-regulated in 24 (55.8%) of tumor specimens. Even though the promoter of CHD5 was hypermethylated in 8 patients, it was not found associated with CHD5 gene expression (p=0.08). Akt phosphorylation was increased in 14 (53.8%) and decreased in 12 (46.2%) of the samples but no significant association was found between p-Akt phosphorylation and CHD5 expression (p=0.67). We suggest that CHD5 may act as a tumor suppressor gene in NSCLC.
