Identification of four genes as novel susceptibility loci for early-onset type 2 diabetes mellitus, metabolic syndrome, or hyperuricemia.

Biomed Rep 2018 Jul 29;9(1):21-36. Epub 2018 May 29.

CREST, Japan Science and Technology Agency, Kawaguchi, Saitama 332-0012, Japan.

Given that early-onset type 2 diabetes mellitus (T2DM), metabolic syndrome (MetS), and hyperuricemia have been shown to have strong genetic components, the statistical power of a genetic association study may be increased by focusing on early-onset subjects with these conditions. Although genome-wide association studies have identified various genes and loci significantly associated with T2DM, MetS, and hyperuricemia, genetic variants that contribute to predisposition to these conditions in Japanese subjects remain to be identified definitively. We performed exome-wide association studies (EWASs) for early-onset T2DM, MetS, or hyperuricemia to identify genetic variants that confer susceptibility to these conditions. Read More

Requirement of the Mowat-Wilson Syndrome Gene Zeb2 in the Differentiation and Maintenance of Non-photoreceptor Cell Types During Retinal Development.

Mol Neurobiol 2018 Jun 19. Epub 2018 Jun 19.

State Key Laboratory of Ophthalmology, Guangdong Provincial Key Laboratory of Ophthalmology and Visual Science, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, 510060, China.

Mutations in the human transcription factor gene ZEB2 cause Mowat-Wilson syndrome, a congenital disorder characterized by multiple and variable anomalies including microcephaly, Hirschsprung disease, intellectual disability, epilepsy, microphthalmia, retinal coloboma, and/or optic nerve hypoplasia. Zeb2 in mice is involved in patterning neural and lens epithelia, neural tube closure, as well as in the specification, differentiation and migration of neural crest cells and cortical neurons. At present, it is still unclear how Zeb2 mutations cause retinal coloboma, whether Zeb2 inactivation results in retinal degeneration, and whether Zeb2 is sufficient to promote the differentiation of different retinal cell types.

How to make a tongue: Cellular and molecular regulation of muscle and connective tissue formation during mammalian tongue development.

Semin Cell Dev Biol 2018 May 18. Epub 2018 May 18.

Centre for Craniofacial and Regenerative Biology, Kings College London Dental Institute, London, United Kingdom.

The vertebrate tongue is a complex muscular organ situated in the oral cavity and involved in multiple functions including mastication, taste sensation, articulation and the maintenance of oral health. Although the gross embryological contributions to tongue formation have been known for many years, it is only relatively recently that the molecular pathways regulating these processes have begun to be discovered. In particular, there is now evidence that the Hedgehog, TGF-Beta, Wnt and Notch signaling pathways all play an important role in mediating appropriate signaling interactions between the epithelial, cranial neural crest and mesodermal cell populations that are required to form the tongue.

Dental Mesenchymal Stem/Stromal Cells and Their Exosomes.

Stem Cells Int 2018 15;2018:8973613. Epub 2018 Apr 15.

Department of Stem Cell Preparation, St. Elisabeth Cancer Institute, Bratislava, Slovakia.

Stem cells derived from human dental pulp tissue (DP-MSC) differ from the other mesenchymal stem cells prepared from bone marrow or adipose tissue due to their embryonic origin from the neural crest and are of special interest because of their neurotropic character. Furthermore, the therapeutic potential of DP-MSCs is realized through paracrine action of extracellularly released components, for which exosomes play an important role. In this review, we intend to explore the properties of these cells with an emphasis on exosomes. Read More

[Kallmann syndrome with deafness caused by SOX10 mutation: Advances in research].

Zhonghua Nan Ke Xue 2017 Sep;23(9):838-841

PLA Research Institute of Clinical Laboratory Medicine, Jingling Hospital, Nanjing University School of Medicine / Nanjing General Hospital of Nanjing Military Region, Nanjing, Jiangsu 210002, China.

The transcription factor SOX10, as a major actor in the development of the neural crest, plays a key role in the maintenance of progenitor cell multipotency, lineage specification, and cell differentiation. Abnormalities of neural crest development in humans lead to a number of genetic diseases known as neurocristopathies or neural crest disorders. The mutation of SOX10 can cause Kallmann syndrome (KS), which is a clinically and genetically heterogeneous condition and defined by the association between anosmia and hypogonadotropic hypogonadism due to incomplete migration of neuroendocrine gonadotropin-releasing hormone (GnRH) cells along the olfactory, vomeronasal, and terminal nerves.

Kearns-Sayre syndrome with facial and white matter extensive involvement: a (mitochondrial and nuclear gene related?) neurocristopathy?

Pediatr Med Chir 2017 Dec 15;39(4):169. Epub 2017 Dec 15.

Department of Neurosciences, Ophthalmology, Rehabilitation, Genetics, and Mother-Child Sciences, University of Genoa, Genoa.

The Authors report on a patient with Kearns-Sayre syndrome, large mtDNA deletion (7/kb), facial abnormalities and severe central nervous system (CNS) white matter radiological features, commonly attributed to spongy alterations. The common origin from neural crest cell (NCC) of facial structures (cartilagineous, osseous, vascular and of the peripheral nervous system) and of peripheral glia and partially of the CNS white matter are underlined and the facial and glial abnormalities are attributed to the abnormal reproduction/migration of NCC. In this view, the CNS spongy alterations in KSS may be not only a dystrophic process (leukodystrophy) but also a dysplastic condition (leukodysplasia). Read More

Chromatin remodeler CHD7 regulates the stem cell identity of human neural progenitors.

Genes Dev 2018 01 9;32(2):165-180. Epub 2018 Feb 9.

Department of Physiology, Keio University School of Medicine, Shinjuku-ku, Tokyo 160-8582, Japan.

Multiple congenital disorders often present complex phenotypes, but how the mutation of individual genetic factors can lead to multiple defects remains poorly understood. In the present study, we used human neuroepithelial (NE) cells and CHARGE patient-derived cells as an in vitro model system to identify the function of chromodomain helicase DNA-binding 7 (CHD7) in NE-neural crest bifurcation, thus revealing an etiological link between the central nervous system (CNS) and craniofacial anomalies observed in CHARGE syndrome. We found that CHD7 is required for epigenetic activation of superenhancers and CNS-specific enhancers, which support the maintenance of the NE and CNS lineage identities. Read More

Sema3a plays a role in the pathogenesis of CHARGE syndrome.

Hum Mol Genet 2018 Apr;27(8):1343-1352

Institute of Human Genetics, University Medical Center Göttingen, 37073 Göttingen, Germany.

CHARGE syndrome is an autosomal dominant malformation disorder caused by heterozygous loss of function mutations in the chromatin remodeler CHD7. Chd7 regulates the expression of Sema3a, which also contributes to the pathogenesis of Kallmann syndrome, a heterogeneous condition with the typical features hypogonadotropic hypogonadism and an impaired sense of smell. Both features are common in CHARGE syndrome suggesting that SEMA3A may provide a genetic link between these syndromes. Read More

Institute of Molecular and Cell Biology, University of Tartu, 23 Riia St, Tartu, 51010, Estonia.

Autosomal recessive disorders such as Fukuyama congenital muscular dystrophy, Walker-Warburg syndrome, and the muscle-eye-brain disease are characterized by defects in the development of patient's brain, eyes, and skeletal muscles. These syndromes are accompanied by brain malformations like type II lissencephaly in the cerebral cortex with characteristic overmigrations of neurons through the breaches of the pial basement membrane. The signaling pathways activated by laminin receptors, dystroglycan and integrins, control the integrity of the basement membrane, and their malfunctioning may underlie the pathologies found in the rise of defects reminiscent of these syndromes.

Gene expression of the two developmentally regulated dermatan sulfate epimerases in the Xenopus embryo.

PLoS One 2018 25;13(1):e0191751. Epub 2018 Jan 25.

Department of Laboratory Medicine, Lund Stem Cell Center, Lund University, Lund, Sweden.

Chondroitin sulfate (CS)/dermatan sulfate (DS) proteoglycans are abundant on the cell surface and in the extracellular matrix and have important functions in matrix structure, cell-matrix interaction and signaling. The DS epimerases 1 and 2, encoded by Dse and Dsel, respectively, convert CS to a CS/DS hybrid chain, which is structurally and conformationally richer than CS, favouring interaction with matrix proteins and growth factors. We recently showed that Xenopus Dse is essential for the migration of neural crest cells by allowing cell surface CS/DS proteoglycans to adhere to fibronectin. Read More

Tissue-selective effects of nucleolar stress and rDNA damage in developmental disorders.

Nature 2018 02 24;554(7690):112-117. Epub 2018 Jan 24.

Department of Chemical and Systems Biology, Stanford University School of Medicine, Stanford, California 94305, USA.

Many craniofacial disorders are caused by heterozygous mutations in general regulators of housekeeping cellular functions such as transcription or ribosome biogenesis. Although it is understood that many of these malformations are a consequence of defects in cranial neural crest cells, a cell type that gives rise to most of the facial structures during embryogenesis, the mechanism underlying cell-type selectivity of these defects remains largely unknown. By exploring molecular functions of DDX21, a DEAD-box RNA helicase involved in control of both RNA polymerase (Pol) I- and II-dependent transcriptional arms of ribosome biogenesis, we uncovered a previously unappreciated mechanism linking nucleolar dysfunction, ribosomal DNA (rDNA) damage, and craniofacial malformations.

microRNAs associated with early neural crest development in Xenopus laevis.

BMC Genomics 2018 01 18;19(1):59. Epub 2018 Jan 18.

School of Biological Sciences, University of East Anglia, Norwich Research Park, Norwich, NR4 7TJ, UK.

Background: The neural crest (NC) is a class of transitory stem cell-like cells unique to vertebrate embryos. NC cells arise within the dorsal neural tube where they undergo an epithelial to mesenchymal transition in order to migrate and differentiate throughout the developing embryo. The derivative cell types give rise to multiple tissues, including the craniofacial skeleton, peripheral nervous system and skin pigment cells. Read More

Identification of three genetic variants as novel susceptibility loci for body mass index in a Japanese population.

Physiol Genomics 2018 Mar 12;50(3):179-189. Epub 2018 Jan 12.

Department of Human Functional Genomics, Advanced Science Research Promotion Center, Mie University, Tsu, Mie , Japan.

Recent genome-wide association studies have identified various obesity or metabolic syndrome (MetS) susceptibility loci. However, most studies were conducted in a cross-sectional manner. To address this gap, we performed a longitudinal exome-wide association study to identify susceptibility loci for obesity and MetS in a Japanese population. Read More

Orthognathic surgery in Melnick-Needles syndrome: a review of the literature and report of two siblings.

Int J Oral Maxillofac Surg 2018 Jun 12;47(6):738-742. Epub 2018 Jan 12.

Department of Oral and Maxillofacial Surgery, St James's Hospital, Dublin, Ireland.

Melnick-Needles syndrome (MNS) is a rare congenital X-linked dominant skeletal dysplasia, characterized by exophthalmos, a prominent forehead, and mandibular hypoplasia and retrognathism. Dental features may include anodontia, hypodontia, or oligodontia. Increased collagen content, unpredictable collagen synthesis, and abnormal bony architecture have raised concerns regarding bone splitting intraoperatively and bone healing postoperatively.

Dysregulation of cotranscriptional alternative splicing underlies CHARGE syndrome.

Proc Natl Acad Sci U S A 2018 Jan 8;115(4):E620-E629. Epub 2018 Jan 8.

Molecular Genetics of Development Laboratory, Department of Biological Sciences, University of Quebec at Montreal, Montreal, QC H2X 3Y7, Canada;

CHARGE syndrome-which stands for coloboma of the eye, heart defects, atresia of choanae, retardation of growth/development, genital abnormalities, and ear anomalies-is a severe developmental disorder with wide phenotypic variability, caused mainly by mutations in (chromodomain helicase DNA-binding protein 7), known to encode a chromatin remodeler. The genetic lesions responsible for mutation-negative cases are unknown, at least in part because the pathogenic mechanisms underlying CHARGE syndrome remain poorly defined. Here, we report the characterization of a mouse model for mutation-negative cases of CHARGE syndrome generated by insertional mutagenesis of (family with sequence similarity 172, member A).

Improvement in anthropometric parameters after rational dietary intervention in women with Polycystic Ovary Syndrom as the best method to support treatment

Rocz Panstw Zakl Hig 2017;68(4):409-417

Pomeranian Medical University in Szczecin, Clinic of Gynecology and Urogynecology, Broniewskiego 24, 71-460 Szczecin, Poland

Background: Polycystic ovary syndrome (PCOS) is a disorder often occurring in women at reproductive age. An important factor in PCOS pathogenesis is insulin resistance, which pronounces hyperandrogenism and leads to the development of various metabolic disorders

Objectives: The aim of this study is to determine the effect of reduction diet with low glycemic index (GI) on anthropometric parameters of women with PCOS and the assessment of the effectiveness of the diet on body mass and adipose tissue reduction

Material And Methods: The study was performed on 24 women with PCOS diagnosed with Rotterdam’s criteria. Anthropometric measurements and bioelectrical impedance were performed. Read More

Anosmin-1 is essential for neural crest and cranial placodes formation in Xenopus.

Biochem Biophys Res Commun 2018 01 22;495(3):2257-2263. Epub 2017 Dec 22.

Department of Basic Science & Craniofacial Biology, College of Dentistry, New York University, New York, USA. Electronic address:

During embryogenesis vertebrates develop a complex craniofacial skeleton associated with sensory organs. These structures are primarily derived from two embryonic cell populations the neural crest and cranial placodes, respectively. Neural crest cells and cranial placodes are specified through the integrated action of several families of signaling molecules, and the subsequent activation of a complex network of transcription factors.
