We performed an epigenome-wide longitudinal DNAm study of a well-characterized sample of young women from the Swedish Born into Life study, with repeated blood sampling before, during and after pregnancy (n = 21), using the Illumina Infinium MethylationEPIC array. We conducted a replication in the Isle of Wight third-generation birth cohort (n = 27), using the Infinium HumanMethylation450k BeadChip. We identified 196 CpG sites displaying intra-individual longitudinal change in DNAm with a false discovery rate (FDR) P < .05. Most of these (91%) showed a decrease in average methylation levels over the studied period. We observed several genes represented by ⩾3 differentially methylated CpGs: HOXB3, AVP, LOC100996291, and MicroRNA 10a. Of 36 CpGs available in the replication cohort, 17 were replicated, all but 2 with the same direction of association (replication P < .05). Biological pathway analysis demonstrated that FDR-significant CpGs belong to genes overrepresented in metabolism-related pathways, such as adipose tissue development, regulation of insulin receptor signaling, and mammary gland fat development. These results contribute to a better understanding of the biological mechanisms underlying important physiological alterations and adaptations for pregnancy and lactation.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865719867090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10803414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of customizable platforms that allow precise genomic targeting has opened the possibility to cure genetic disorders by tackling directly the origin of the disease. Indeed, tethering of different effectors to a DNA-binding moiety grants precise alterations of the genome, transcriptome, or epigenome with the aim of normalizing disease-causing aberrations. The use of designer nucleases for therapeutic genome editing is currently approaching the clinics, and safety concerns arise with respect to off-target effects. Epigenome editing might be a valuable alternative, as it does not rely on DNA double-strand breaks, one of the most deleterious form of DNA damage, to exert its function. We have recently described designer epigenome modifier (DEM), a novel platform for achieving precise epigenome editing in clinically relevant primary human cells. We discuss the efficiency of DEM and highlight their remarkable safety profile, which certainly makes this platform a valuable candidate for future clinical translation.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865718818838","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36793703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A substantial part of the genome encompasses repeats and when such repeats are in the coding region they may lead to change in the gene expression profile followed by pathological conditions. Structural variants are alterations which change one or more sequence feature in the chromosome such as change in the copy number, rearrangements, and translocations of a sequence and can be balanced or unbalanced. Copy number variants (CNVs) may increase or decrease the copies of a given region and have a pivotal role in the onset of many diseases including cardiovascular disorders. Cardiovascular disorders have a magnitude of well-established risk factors and etiology, but their correlation with CNVs is still being studied. In this article, we have discussed history of CNVs and a summary on the diseases associated with CNVs. To detect such variations, we shed light on the number of techniques introduced so far and their limitations. The lack of studies on cardiovascular diseases to determine the frequency of such variants needs clinical studies with larger cohorts. This review is a compilation of articles suggesting the importance of CNVs in multitude of cardiovascular anomalies. Finally, future perspectives for better understanding of CNVs and cardiovascular disorders have also been discussed.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865718818839","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36781978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were analyzed using a variety of descriptive and inferential statistical tests.Results: The overwhelming majority (>94%) of participants considered prenatal genetic testing, particularly non-invasive prenatal genetic screening, procedures to be good, comfortable, and reasonable, even when the non-diagnostic nature of non-invasive prenatal genetic screening was explained. Likewise, 95% encouraged the implementation of non-invasive prenatal genetic screening within the Jordanian health system, but most preferred it to remain optional. However, women in higher-risk age brackets, in consanguineous marriages, and with less education were significantly less interested in learning about non-invasive prenatal genetic screening. Only 60% of women interviewed were satisfied with the services provided by their obstetric/gynecologist. The more satisfied the women were, the more they are likely to adapt non-invasive prenatal genetic screening.Conclusions: In sum, although the data support the receptivity of Jordanian women to national implementation of non-invasive prenatal genetic screening, such policies should be accompanied by health education to increase the genetic literacy of the population and to engage high-risk populations. Thus, this offers rare insight into the readiness of 1 particular Arab population to adapt non-invasive prenatal genetic screening technologies.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865718813122","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36843332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the requirement of polyamines in tumor cells is stepped up to maintain tumorigenicity. Many synthetic polyamine analogues have been designed recently to target the polyamine metabolism in tumors to induce apoptosis. N4-Erucoyl spermidine (designed as N4-Eru), a novel acylspermidine derivative, has been shown to exert selective inhibitory effects on both hematological and solid tumors, but its mechanisms of action are unknown. In this study, RNA sequencing was performed to investigate the anticancer mechanisms of N4-Eru-treated T-cell acute lymphoblastic leukemia (ALL) cell line (Jurkat cells), and gene expression was examined through different tools. We could show that many key oncogenes including NDRG1, CACNA1G, TGFBR2, NOTCH1,2,3, UHRF1, DNMT1,3, HDAC1,3, KDM3A, KDM4B, KDM4C, FOS, and SATB1 were downregulated, whereas several tumor suppressor genes such as CDKN2AIPNL, KISS1, DDIT3, TP53I13, PPARG, FOXP1 were upregulated. Data obtained through RNA-Seq further showed that N4-Eru inhibited the NOTCH/Wnt/JAK-STAT axis. This study also indicated that N4-Eru-induced apoptosis could involve several key signaling pathways in cancer. Altogether, our results suggest that N4-Eru is a promising drug to treat ALL.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2018-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865718814543","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36750845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overexpression of transcription factors in somatic cells enables the induction of induced pluripotent stem cells (iPSCs). This process entails genome-wide remodeling of DNA methylation, chromatin, and transcription. Recent work suggests that the number of active X chromosomes present in a cell influences remodeling of DNA methylation during somatic cell reprogramming to mouse iPSCs. Female iPSCs with 2 active X chromosomes display global DNA hypomethylation, whereas male XY iPSCs show DNA methylation levels similar to the somatic cells they are derived from. Global DNA methylation erasure in female iPSCs takes place genome-wide and involves repression of DNA methyltransferases. However, on loss of one X chromosome, female iPSCs acquire a DNA methylation landscape resembling that of XY iPSCs. Therefore, it is the X chromosome dosage that dictates global DNA methylation levels in iPSCs. Here, we discuss the evidence that links X chromosome dosage with the regulation of DNA methylation in pluripotent stem cells. We focus on iPSCs reprogramming studies, where X chromosome status is a novel factor impacting our understanding of epigenetic remodeling.","PeriodicalId":41996,"journal":{"name":"Epigenetics Insights","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2018-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/2516865718802931","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36690071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
