Open Access Baghdad Science Journal P-ISSN: 2078-8665 2020, 17(2):463-470 E-ISSN: 2411-7986 DOI: http://dx.doi.org/10.21123/bsj.2020.17.2.0463 In Silico Analysis of Regulatory Elements of the Vitamin D Receptor Shirin Farivar 1 Roya Amirinejad 2 Bahar Naghavi gargari 3 Seyedeh Batool Hassani 4 Zeinab Shirvani-Farsani 1* Received 26/2/2019, Accepted 5/1/2020, Published 1/6/2020 This work is licensed under a Creative Commons Attribution 4.0 International License. Abstract Vitamin D receptor (VDR) is a nuclear transcription factor that controls gene expression. Its impaired expression was found to be related to different diseases. VDR also acts as a regulator of different pathways including differentiation, inflammation, calcium and phosphate absorption, etc. but there is no sufficient knowledge about the regulation of the gene itself. Therefore, a better understanding of the genetic and epigenetic factors regulating the VDR may facilitate the improvement of strategies for the prevention and treatment of diseases associated with dysregulation of VDR. In the present investigation, a set of databases and methods were used to identify putative functional elements in the VDR locus. Histone modifications, CpG Islands, epigenetic marks at VDR locus were indicated. In addition, repeated sequences, enhancers, insulators, transcription factor binding sites and targets of the VDR gene, as well as protein- protein interactions with bioinformatics tools, were reported. Some of these genetic elements had overlapped with CpG Islands. These results revealed important new insight into the molecular mechanisms of the VDR gene regulation in human cells and tissues. Key words: CpG Islands, Epigenetics, In silico analysis, Regulation elements, VDR Introduction: Vitamin D is a steroid hormone that multiple sclerosis (10), Rheumatoid Arthritis and balances calcium and phosphate levels and is Systemic Lupus Erythematosus (11), cardiovascular crucial for bone structure. -

The Oviductal Extracellular Vesicles' RNA Cargo Regulates the Bovine
International Journal of Molecular Sciences Article The Oviductal Extracellular Vesicles’ RNA Cargo Regulates the Bovine Embryonic Transcriptome Stefan Bauersachs 1 , Pascal Mermillod 2 and Carmen Almiñana 1,2,* 1 Genetics and Functional Genomics, VetSuisse Faculty Zurich, University of Zurich, 8315 Lindau (ZH), Switzerland; [email protected] 2 UMR85 PRC, INRA, CNRS 7247, Université de Tours, IFCE, 37380 Nouzilly, France; [email protected] * Correspondence: [email protected] Received: 21 January 2020; Accepted: 12 February 2020; Published: 14 February 2020 Abstract: Oviductal extracellular vesicles (oEVs) are emerging as key players in the gamete/embryo–oviduct interactions that contribute to successful pregnancy. Various positive effects of oEVs on gametes and early embryos have been found in vitro. To determine whether these effects are associated with changes of embryonic gene expression, the transcriptomes of embryos supplemented with bovine fresh (FeEVs) or frozen (FoEVs) oEVs during in vitro culture compared to controls without oEVs were analyzed by low-input RNA sequencing. Analysis of RNA-seq data revealed 221 differentially expressed genes (DEGs) between FoEV treatment and control, 67 DEGs for FeEV and FoEV treatments, and minor differences between FeEV treatment and control (28 DEGs). An integrative analysis of mRNAs and miRNAs contained in oEVs obtained in a previous study with embryonic mRNA alterations pointed to direct effects of oEV cargo on embryos (1) by increasing the concentration of delivered transcripts; (2) by translating delivered mRNAs to proteins that regulate embryonic gene expression; and (3) by oEV-derived miRNAs which downregulate embryonic mRNAs or modify gene expression in other ways. Our study provided the first high-throughput analysis of the embryonic transcriptome regulated by oEVs, increasing our knowledge on the impact of oEVs on the embryo and revealing the oEV RNA components that potentially regulate embryonic development. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Smu1 and RED Are Required for Activation of Spliceosomal B Complexes Assembled on Short Introns
ARTICLE https://doi.org/10.1038/s41467-019-11293-8 OPEN Smu1 and RED are required for activation of spliceosomal B complexes assembled on short introns Sandra Keiper 1, Panagiotis Papasaikas 2,4,5, Cindy L. Will1, Juan Valcárcel2,3, Cyrille Girard1 & Reinhard Lührmann1 1234567890():,; Human pre-catalytic spliceosomes contain several proteins that associate transiently just prior to spliceosome activation and are absent in yeast, suggesting that this critical step is more complex in higher eukaryotes. We demonstrate via RNAi coupled with RNA-Seq that two of these human-specific proteins, Smu1 and RED, function both as alternative splicing regulators and as general splicing factors and are required predominantly for efficient splicing of short introns. In vitro splicing assays reveal that Smu1 and RED promote spliceosome activation, and are essential for this step when the distance between the pre-mRNA’s5′ splice site (SS) and branch site (BS) is sufficiently short. This Smu1-RED requirement can be bypassed when the 5′ and 3′ regions of short introns are physically separated. Our obser- vations suggest that Smu1 and RED relieve physical constraints arising from a short 5′SS-BS distance, thereby enabling spliceosomes to overcome structural challenges associated with the splicing of short introns. 1 Department of Cellular Biochemistry, Max Planck Institute for Biophysical Chemistry, Am Fassberg 11, 37077 Göttingen, Germany. 2 Centre de Regulació Genòmica, The Barcelona Institute of Science and Technology and Universitat Pompeu Fabra, Dr. Aiguader 88, 08003 Barcelona, Spain. 3 Institució Catalana de Recerca i Estudis Avançats (ICREA), Pg.

Key words: SVA, trans-mobilisation, behaviour, brain, evolution, psychiatric disorders 1 Abstract The hominid-specific non-LTR retrotransposon termed SINE–VNTR–Alu (SVA) is the youngest of the transposable elements in the human genome. The propagation of the most ancient SVA type A took place about 13.5 Myrs ago, and the youngest SVA types appeared in the human genome after the chimpanzee divergence. Functional enrichment analysis of genes associated with SVA insertions demonstrated their strong link to multiple ontological categories attributed to brain function and the disorders. SVA types that expanded their presence in the human genome at different stages of hominoid life history were also associated with progressively evolving behavioural features that indicated a potential impact of SVA propagation on a cognitive ability of a modern human. -
High-Fidelity CRISPR/Cas9

Zeisberg1,2 & Michael Zeisberg2,3 fi 1234567890():,; While suppression of speci c genes through aberrant promoter methylation contributes to different diseases including organ fibrosis, gene-specific reactivation technology is not yet available for therapy. TET enzymes catalyze hydroxymethylation of methylated DNA, reac- tivating gene expression. We here report generation of a high-fidelity CRISPR/Cas9-based gene-specific dioxygenase by fusing an endonuclease deactivated high-fidelity Cas9 (dHFCas9) to TET3 catalytic domain (TET3CD), targeted to specific genes by guiding RNAs (sgRNA). We demonstrate use of this technology in four different anti-fibrotic genes in different cell types in vitro, among them RASAL1 and Klotho, both hypermethylated in kidney fibrosis. Furthermore, in vivo lentiviral delivery of the Rasal1-targeted fusion protein to interstitial cells and of the Klotho-targeted fusion protein to tubular epithelial cells each results in specific gene reactivation and attenuation of fibrosis, providing gene-specific demethylating technology in a disease model. 1 Department of Cardiology and Pneumology, University Medical Center Göttingen, Robert-Koch-Str. 40, 37075 Göttingen, Germany. 2 German Center for Cardiovascular Research (DZHK) Partner Site, Göttingen, Germany. 3 Department of Nephrology and Rheumatology, University Medical Center Göttingen, Robert-Koch-Str. 40, 37075 Göttingen, Germany. 4 Department of Pathology and Medical Biology, University Medical Center Groningen, Hanzeplein 1, 9713 Groningen, GZ, Netherlands. -

Transcription-Replication Collisions—A Series of Unfortunate Events
biomolecules Review Transcription-Replication Collisions—A Series of Unfortunate Events Commodore St Germain 1,2,*, Hongchang Zhao 2 and Jacqueline H. Barlow 2,* 1 School of Mathematics and Science, Solano Community College, 4000 Suisun Valley Road, Fairfield, CA 94534, USA 2 Department of Microbiology and Molecular Genetics, University of California Davis, One Shields Avenue, Davis, CA 95616, USA; [email protected] * Correspondence: [email protected] (C.S.G.); [email protected] (J.H.B.) Abstract: Transcription-replication interactions occur when DNA replication encounters genomic regions undergoing transcription. Both replication and transcription are essential for life and use the same DNA template making conflicts unavoidable. R-loops, DNA supercoiling, DNA secondary structure, and chromatin-binding proteins are all potential obstacles for processive replication or transcription and pose an even more potent threat to genome integrity when these processes co-occur. It is critical to maintaining high fidelity and processivity of transcription and replication while navigating through a complex chromatin environment, highlighting the importance of defining cellular pathways regulating transcription-replication interaction formation, evasion, and resolution. Here we discuss how transcription influences replication fork stability, and the safeguards that have evolved to navigate transcription-replication interactions and maintain genome integrity in mammalian cells.
