Currently, the diagnosis mainly depends on clinical manifestations and genetic testing. To date, there is no report on the identification Kabuki syndrome in fetuses using chromosomal microarray analysis (CMA). Case presentation: A fetus was identified with growth retardation and cardiovascular abnormality on color Doppler ultrasonography; however, non-invasive prenatal testing (NIPT) revealed a low risk and G-banding karyotyping revealed no abnormal karyotype detected. CMA identified a 1.3 Mb deletion on the X chromosome (Xp11.3) containing KDM6A, DUSP21, MIR222, MIR221 and CXorf36 genes. The fetus was diagnosed with Kabuki syndrome 2, and labor was induced. In addition, CMA detected a 1.3 Mb deletion in the chromosome Xp11.3 in the mother, which contains 5 genes namely KDM6A, DUSP21, MIR222, MIR221 and CXorf36, while no chromosomal abnormality was identified in the father. Conclusions: We report a fetus with Kabuki syndrome 2 detected using CMA. -
High-Throughput Sequencing of Human Plasma RNA by Using Thermostable Group II Intron Reverse Transcriptases

LAMBOWITZ1,2 1Institute for Cellular and Molecular Biology, University of Texas at Austin, Austin, Texas 78712, USA 2Department of Molecular Biosciences, University of Texas at Austin, Austin, Texas 78712, USA ABSTRACT Next-generation RNA-sequencing (RNA-seq) has revolutionized transcriptome profiling, gene expression analysis, and RNA-based diagnostics. Here, we developed a new RNA-seq method that exploits thermostable group II intron reverse transcriptases (TGIRTs) and used it to profile human plasma RNAs. TGIRTs have higher thermostability, processivity, and fidelity than conventional reverse transcriptases, plus a novel template-switching activity that can efficiently attach RNA-seq adapters to target RNA sequences without RNA ligation. The new TGIRT-seq method enabled construction of RNA-seq libraries from <1 ng of plasma RNA in <5 h. TGIRT-seq of RNA in 1-mL plasma samples from a healthy individual revealed RNA fragments mapping to a diverse population of protein-coding gene and long ncRNAs, which are enriched in intron and antisense sequences, as well as nearly all known classes of small ncRNAs, some of which have never before been seen in plasma. Surprisingly, many of the small ncRNA species were present as full-length transcripts, suggesting that they are protected from plasma RNases in ribonucleoprotein (RNP) complexes and/or exosomes. -

Development of Novel Therapeutic Agents by Inhibition of Oncogenic Micrornas
International Journal of Molecular Sciences Review Development of Novel Therapeutic Agents by Inhibition of Oncogenic MicroRNAs Dinh-Duc Nguyen and Suhwan Chang * ID Department of Biomedical Sciences, University of Ulsan College of Medicine, Asan Medical Center, Seoul 05505, Korea; [email protected] * Correspondence: [email protected] Received: 21 November 2017; Accepted: 22 December 2017; Published: 27 December 2017 Abstract: MicroRNAs (miRs, miRNAs) are regulatory small noncoding RNAs, with their roles already confirmed to be important for post-transcriptional regulation of gene expression affecting cell physiology and disease development. Upregulation of a cancer-causing miRNA, known as oncogenic miRNA, has been found in many types of cancers and, therefore, represents a potential new class of targets for therapeutic inhibition. Several strategies have been developed in recent years to inhibit oncogenic miRNAs. Among them is a direct approach that targets mature oncogenic miRNA with an antisense sequence known as antimiR, which could be an oligonucleotide or miRNA sponge. In contrast, an indirect approach is to block the biogenesis of miRNA by genome editing using the CRISPR/Cas9 system or a small molecule inhibitor. The development of these inhibitors is straightforward but involves significant scientific and therapeutic challenges that need to be resolved. In this review, we summarize recent relevant studies on the development of miRNA inhibitors against cancer. Keywords: antimiR; antagomiR; miRNA-sponge; oncomiR; CRISPR/Cas9; cancer therapeutics 1. Introduction Cancer has been the leading cause of death and a major health problem worldwide for many years; basically, it results from out-of-control cell proliferation. Traditionally, several key proteins have been identified and found to affect signaling pathways regulating cell cycle progression, apoptosis, and gene transcription in various types of cancers [1,2]. -

Habeos1* 1 Department of Internal Medicine, Division of Endocrinology, Medical School, University of Patras, Patras, Greece, 2 Laboratory of Clinical Virology, Medical School, University of Crete, Heraklion, Greece Abstract Obesity is a major health concern worldwide which is associated with increased risk of chronic diseases such as metabolic syndrome, cardiovascular disease and cancer. The elucidation of the molecular mechanisms involved in adipogenesis and obesogenesis is of essential importance as it could lead to the identification of novel biomarkers and therapeutic targets for the development of anti-obesity drugs. MicroRNAs (miRNAs) have been shown to play regulatory roles in several biological processes. They have become a growing research field and consist of promising pharmaceutical targets in various fields such as cancer, metabolism, etc. The present study investigated the possible implication of miRNAs in adipose tissue during the development of obesity using as a model the C57BLJ6 mice fed a high-fat diet. C57BLJ6 wild type male mice were fed either a standard (SD) or a high-fat diet (HFD) for 5 months. Total RNA was prepared from white adipose tissue and was used for microRNA profiling and qPCR. Twenty-two of the most differentially expressed miRNAs, as identified by the microRNA profiling were validated using qPCR. The results of the present study confirmed previous results. The up- regulation of mmu-miR-222 and the down-regulation of mmu-miR-200b, mmu-miR-200c, mmu-miR-204, mmu-miR-30a*, mmu-miR-193, mmu-miR-378 and mmu-miR-30e* after HFD feeding has also been previously reported. -

Prion diseases comprise a singular group of neurodegenerative conditions caused by endoge- nous, misfolded pathogenic (prion) proteins, associated with molecular aggregates. In humans, classical prion diseases include Creutzfeldt–Jakob disease, fatal familial insomnia, Gerstmann– Sträussler–Scheinker syndrome, and kuru. The aim of this review is to present the connections between miRNAs and prions, exploring how the interaction of both molecular actors may help understand the susceptibility, onset, progression, and pathological findings typical of such disorders, as well as the interface with some prion-like disorders, such as Alzheimer’s. Additionally, due to the inter-regulation of prions and miRNAs in health and disease, potential biomarkers for non-invasive miRNA-based diagnostics, as well as possible miRNA-based therapies to restore the levels of dereg- Citation: Contiliani, D.F.; Ribeiro, Y.d.A.; de Moraes, V.N.; Pereira, T.C. -

Dynamic and Modularized Microrna Regulation and Its Implication in Human Cancers

The altered availability of microRNAs, target mRNAs, and other types of endogenous RNAs competing for microRNA interactions refects the dynamic and conditional property of microRNA- mediated gene regulation that remains under-investigated. Here we propose a new integrative method to study this dynamic process by considering both competing and cooperative mechanisms and identifying functional modules where diferent microRNAs co-regulate the same functional process. Specifcally, a new pipeline was built based on a meta-Lasso regression model and the proof-of-concept study was performed using a large-scale genomic dataset from ~4,200 patients with 9 cancer types. In the analysis, 10,726 microRNA-mRNA interactions were identifed to be associated with a specifc stage and/or type of cancer, which demonstrated the dynamic and conditional miRNA regulation during cancer progression. On the other hands, we detected 4,134 regulatory modules that exhibit high fdelity of microRNA function through selective microRNA-mRNA binding and modulation. For example, miR-18a-3p, −320a, −193b-3p, and −92b-3p co-regulate the glycolysis/gluconeogenesis and focal adhesion in cancers of kidney, liver, lung, and uterus. Furthermore, several new insights into dynamic microRNA regulation in cancers have been discovered in this study. Mature microRNAs (miRNAs) are typically 20–25 nucleotides long.
