Nutrition and its role in human evolution.

J Intern Med 2019 Feb 17. Epub 2019 Feb 17.

Vice Chancellor and Dean for Agriculture and Life Sciences, Texas A&M AgriLife, College Station, TX, USA.

Our understanding of human evolution has improved rapidly over recent decades, facilitated by large-scale cataloguing of genomic variability amongst both modern and archaic humans. It seems clear that the evolution of the ancestors of chimpanzees and hominins separated 7-9 million years ago with some migration out of Africa by the earlier hominins; Homo sapiens slowly emerged as climate change resulted in drier, less forested African conditions. The African populations expanded and evolved in many different conditions with slow mutation and selection rates in the human genome, but with much more rapid mutation occurring in mitochondrial DNA.

Trehalose restores functional autophagy suppressed by high glucose.

Reprod Toxicol 2019 Feb 12. Epub 2019 Feb 12.

Department of Obstetrics, Gynecology & Reproductive Sciences, Baltimore, Maryland, USA; Department of Biochemistry & Molecular Biology, University of Maryland School of Medicine, Baltimore, Maryland, USA. Electronic address:

Autophagy is required for neurulation, and autophagy activators with minimal toxicity, such as the natural compound trehalose, a nonreducing disaccharide, possess high therapeutic value. To determine whether trehalose directly induces autophagy, FITC-labeled trehalose was used for tracing its presence in autophagosome complexes. Trehalose was as potent as rapamycin and starvation in inducing de novo autophagosome formation and increasing autophagosome flux in GFP-LC3 reporter cells and C17. Read More

Chitosan tubes enriched with fresh skeletal muscle fibers for delayed repair of peripheral nerve defects.

Neural Regen Res 2019 Jun;14(6):1079-1084

Department of Clinical and Biological Sciences; Neuroscience Institute Cavalieri Ottolenghi, University of Torino, Torino, Italy.

Nerve regeneration after delayed nerve repair is often unsuccessful. Indeed, the expression of genes associated with regeneration, including neurotrophic and gliotrophic factors, is drastically reduced in the distal stump of chronically transected nerves; moreover, Schwann cells undergo atrophy, losing their ability to sustain regeneration. In the present study, to provide a three-dimensional environment and trophic factors supporting Schwann cell activity and axon re-growth, we combined the use of an effective conduit (a chitosan tube) with a promising intraluminal structure (fresh longitudinal skeletal muscle fibers).

Women's periconceptional lowered carbohydrate intake and NTD-affected pregnancy risk in the era of prefortification with folic acid.

Birth Defects Res 2019 Jan 25. Epub 2019 Jan 25.

Department of Pediatrics, Division of Neonatal and Developmental Medicine, Stanford University School of Medicine, Stanford, California.

Background: A recent study observed women's restricted carbohydrate diet in the year before conception was associated with increased risk of neural tube defect (NTD)-affected pregnancies. That study corresponded to the era of postfortification of folic acid. Because folic acid and carbohydrate measures would derive from similar foods, investigators of that study could not determine whether the increased risk with restricted carbohydrate intake was a consequence of lower folate intake.

Phenotypic analysis of Myo10 knockout (Myo10) mice lacking full-length (motorized) but not brain-specific headless myosin X.

Sci Rep 2019 Jan 24;9(1):597. Epub 2019 Jan 24.

Institut für Molekulare Zellbiologie, Westfälische Wilhelms-Universität Münster, 48149, Münster, Germany.

We investigated the physiological functions of Myo10 (myosin X) using Myo10 reporter knockout (Myo10) mice. Full-length (motorized) Myo10 protein was deleted, but the brain-specific headless (Hdl) isoform (Hdl-Myo10) was still expressed in homozygous mutants. In vitro, we confirmed that Hdl-Myo10 does not induce filopodia, but it strongly localized to the plasma membrane independent of the MyTH4-FERM domain. Read More

Folic acid modifies the shape of epithelial cells during morphogenesis via a Folr1 and MLCK dependent mechanism.

Biol Open 2019 Jan 22;8(1). Epub 2019 Jan 22.

The Ohio State University, College of Optometry, Columbus, OH 43210, USA

Folic acid supplementation can prevent neural tube defects, but the specific molecular mechanisms by which it does have not been elucidated. During neural plate morphogenesis, epithelial cell apical constriction cooperates with other events to drive tissue-bending, and when defective, can result in neural tube defects. A Rho-kinase deficient binding mutant of the apical constriction regulating protein, Shroom3 (Shroom3), is one of only a handful of mouse mutant lines with neural tube defects that can be rescued by folic acid supplementation.

Aberrant methylation of Pax3 gene and neural tube defects in association with exposure to polycyclic aromatic hydrocarbons.

Clin Epigenetics 2019 Jan 21;11(1):13. Epub 2019 Jan 21.

Developmental Biology and Cancer Programme, UCL Great Ormond Street Institute of Child Health, University College London, London, WC1N 1EH, UK.

Background: Neural tube defects (NTDs) are common and severe congenital malformations. Pax3 is an essential gene for neural tube closure in mice but it is unknown whether altered expression or methylation of PAX3 contributes to human NTDs. We examined the potential role of hypermethylation of Pax3 in the development of NTDs by analyzing human NTD cases and a mouse model in which NTDs were induced by benzo[a]pyrene (BaP), a widely studied polycyclic aromatic hydrocarbon (PAH).

Tip60- and sirtuin 2-regulated MARCKS acetylation and phosphorylation are required for diabetic embryopathy.

Nat Commun 2019 01 17;10(1):282. Epub 2019 Jan 17.

Department of Obstetrics, Gynecology & Reproductive Sciences, University of Maryland School of Medicine, Baltimore, 21201, MD, USA.

Failure of neural tube closure results in severe birth defects and can be induced by high glucose levels resulting from maternal diabetes. MARCKS is required for neural tube closure, but the regulation and of its biological activity and function have remained elusive. Here, we show that high maternal glucose induced MARCKS acetylation at lysine 165 by the acetyltransferase Tip60, which is a prerequisite for its phosphorylation, whereas Sirtuin 2 (SIRT2) deacetylated MARCKS.

Chromodomain Helicase DNA-Binding Protein 7 Is Suppressed in the Perinecrotic/Ischemic Microenvironment and Is a Novel Regulator of Glioblastoma Angiogenesis.

Stem Cells 2019 Jan 10. Epub 2019 Jan 10.

Department of Cell, Developmental and Integrative Biology, University of Alabama at Birmingham, Birmingham, Alabama, USA.

Tumorigenic and non-neoplastic tissue injury occurs via the ischemic microenvironment defined by low oxygen, pH, and nutrients due to blood supply malfunction. Ischemic conditions exist within regions of pseudopalisading necrosis, a pathological hallmark of glioblastoma (GBM), the most common primary malignant brain tumor in adults. To recapitulate the physiologic microenvironment found in GBM tumors and tissue injury, we developed an in vitro ischemic model and identified chromodomain helicase DNA-binding protein 7 (CHD7) as a novel ischemia-regulated gene.

Prepregnancy counseling: Committee Opinion No. 762.

Authors:

Fertil Steril 2019 Jan;111(1):32-42

American Society for Reproductive Medicine, Birmingham, Alabama; American College of Obstetricians and Gynecologists, Washington, D.C.

The goal of prepregnancy care is to reduce the risk of adverse health effects for the woman, fetus, and neonate by working with the woman to optimize health, address modifiable risk factors, and provide education about healthy pregnancy. All those planning to initiate a pregnancy should be counseled, including heterosexual, lesbian, gay, bisexual, transgender, queer, intersex, asexual, and gender nonconforming individuals. Counseling can begin with the following question: "Would you like to become pregnant in the next year?" Prepregnancy counseling is appropriate whether the reproductive-aged patient is currently using contraception or planning pregnancy. Read More

Systematic Review and Bayesian Meta-analysis of the Dose-response Relationship between Folic Acid Intake and Changes in Blood Folate Concentrations.

Nutrients 2019 Jan 2;11(1). Epub 2019 Jan 2.

Centers for Disease Control and Prevention, National Center on Birth Defects and Developmental Disabilities, Division of Congenital and Developmental Disorders, Atlanta, GA 30341, USA.

The threshold for population-level optimal red blood cell (RBC) folate concentration among women of reproductive age for the prevention of neural tube defects has been estimated at 906 nmol/L; however, the dose-response relationship between folic acid intake and blood folate concentrations is uncharacterized. To estimate the magnitude of blood folate concentration increase in response to specific dosages of folic acid under steady-state conditions (as could be achieved with food fortification), a systematic review of the literature and meta-analysis was conducted. Of the 14,002 records we identified, 533 were selected for full-text review, and data were extracted from 108 articles. Read More

Frontoethmoidal encephalocele presenting in concert with schizencephaly.

Surg Neurol Int 2018 4;9:246. Epub 2018 Dec 4.

Department of Neurosurgery, Aga Khan University Hospital, Karachi, Pakistan.

Background: Schizencephaly is a rare defect which is identified as clefts that are lined with grey matter extending from the ependyma of the cerebral ventricles to the pia mater. An encephalocele occurs due to failure of neural tube closure resulting in a gap through which cerebrospinal fluid and meninges can bulge into a pouch. There have been rare instances when these two defects have presented simultaneously. Read More

The effect of folic acid deficiency on FGF pathway via Brachyury regulation in neural tube defects.

FASEB J 2018 Dec 28:fj201801536R. Epub 2018 Dec 28.

Beijing Municipal Key Laboratory of Child Development and Nutriomics, Capital Institute of Pediatrics, Beijing, China.

Folate deficiency in early development leads to disturbance in multiple processes, including neurogenesis during which fibroblast growth factor (FGF) pathway is one of the crucial pathways. Whether folic acid (FA) directly affects FGF pathways to influence neurodevelopment and the possible mechanism remains unclear. In this study, we presented evidence that in human FA-insufficient encephalocele, the FGF pathway was interfered. Read More

Maternal folate nutrition and offspring health: evidence and current controversies.

Proc Nutr Soc 2018 Dec 26:1-13. Epub 2018 Dec 26.

Nutrition Innovation Centre for Food and Health,School of Biomedical Sciences,Ulster University,Coleraine,Northern Ireland BT52 1SA.

Periconceptional folic acid (FA) is known to have a protective effect in the prevention of neural tube defects (NTD), leading to global recommendations for FA supplementation before and in early pregnancy. Maternal folate throughout pregnancy may have other roles in offspring health, including neurodevelopment and cognitive performance in childhood. Folate is essential for C1 metabolism, a network of pathways involved in several biological processes including nucleotide synthesis, DNA repair and methylation reactions. Read More

PCP-dependent transcellular regulation of actomyosin oscillation facilitates convergent extension of vertebrate tissue.

Dev Biol 2019 Feb 21;446(2):159-167. Epub 2018 Dec 21.

Department of Molecular Biosciences, University of Texas at Austin, 78712, USA.

Oscillatory flows of actomyosin play a key role in the migration of single cells in culture and in collective cell movements in Drosophila embryos. In vertebrate embryos undergoing convergent extension (CE), the Planar Cell Polarity (PCP) pathway drives the elongation of the body axis and shapes the central nervous system, and mutations of the PCP genes predispose humans to various malformations including neural tube defects. However, the spatiotemporal patterns of oscillatory actomyosin contractions during vertebrate CE and how they are controlled by the PCP signaling remain unknown. Read More

Authors:
Adnan Alkhatib

EJIFCC 2018 Dec 5;29(4):280-284. Epub 2018 Dec 5.

Syrian Clinical Laboratories Association, Damascus, Syria.

Pregnancy produces profound physiological changes that increase in significance as it progresses. These changes include hormonal changes, metabolic changes, increases of plasma volume up to 50%, alterations to the balance of the coagulation system in favour of clotting, and GFR increases to a peak 50% above prepregnancy levels. Since healthy physiological changes occur during pregnancy, different reference intervals may be needed. Read More
