In March 2019, 45 scientists and software engineers from around the world converged at the University of California, Santa Cruz for the first pangenomics codeathon. The purpose of the meeting was to propose technical specifications and standards for a usable human pangenome as well as to build relevant tools for genome graph infrastructures. During the meeting, the group held several intense and productive discussions covering a diverse set of topics, including advantages of graph genomes over a linear reference representation, design of new methods that can leverage graph-based data structures, and novel visualization and annotation approaches for pangenomes. Additionally, the …

A Web-Based Calculator For The Prediction Of Severe Neurodevelopmental Impairment In Preterm Infants Using Clinical And Imaging Characteristics, Zachary A Vesoulis, Nathalie M El Ters, Maja Herco, Halana V Whitehead, Amit M Mathur

Open Access Publications

Although the most common forms of brain injury in preterm infants have been associated with adverse neurodevelopmental outcomes, existing MRI scoring systems lack specificity, do not incorporate clinical factors, and are technically challenging to perform. The objective of this study was to develop a web-based, clinically-focused prediction system which differentiates severe neurodevelopmental outcomes from normal-moderate outcomes at two years. Infants were retrospectively identified as those who were born ≤30 weeks gestation and who had MRI imaging at term-equivalent age and neurodevelopmental testing at 18⁻24 months. Each MRI was scored on injury in three domains (intraventricular hemorrhage, white matter injury, and …

Dietary Protein Restriction Reduces Circulating Vldl Triglyceride Levels Via Crebh-Apoa5-Dependent And -Independent Mechanisms, J Humberto Treviño-Villarreal, Valeria Tosti, Nicola Veronese, Beatrice Bertozzi, Arnold D Bullock, Robert S Figenshau, Gerald L Andriole, Luigi Fontana, Et Al

Open Access Publications

Hypertriglyceridemia is an independent risk factor for cardiovascular disease. Dietary interventions based on protein restriction (PR) reduce circulating triglycerides (TGs), but underlying mechanisms and clinical relevance remain unclear. Here, we show that 1 week of a protein-free diet without enforced calorie restriction significantly lowered circulating TGs in both lean and diet-induced obese mice. Mechanistically, the TG-lowering effect of PR was due, in part, to changes in very low-density lipoprotein (VLDL) metabolism both in liver and peripheral tissues. In the periphery, PR stimulated VLDL-TG consumption by increasing VLDL-bound APOA5 expression and promoting VLDL-TG hydrolysis and clearance from circulation. The PR-mediated increase …

Timing And Mechanism Of Conceptus Demise In A Complement Regulatory Membrane Protein Deficient Mouse, Michael P Triebwasser, Xiaobo Wu, Paula Bertram, Dennis E Hourcade, Donald Michael Nelson, John P Atkinson

Open Access Publications

PROBLEM: Crry is a widely expressed type 1 transmembrane complement regulatory protein in rodents which protects self-tissue by downregulating C3 activation. Crry

METHOD OF STUDY: We investigated the basis of Crry

RESULTS: We narrowed the critical period of the complement effect from 6.5 to 8.5 days post-coitus (dpc), which is immediately after the conceptus is exposed to maternal blood. Deposition by 5.5 dpc of maternal C3b on the placental vasculature lacking Crry

CONCLUSION: Our data are most consistent with the deposition of C3b being responsible for the failure of the allantois to fuse to the chorion leading to subsequent conceptus …

During the last half-century, numerous antiinflammatory agents were tested in dozens of clinical trials and have proven ineffective for treating septic shock. The observation in multiple studies that cell-free hemoglobin (CFH) levels are elevated during clinical sepsis and that the degree of increase correlates with higher mortality suggests an alternative approach. Human haptoglobin binds CFH with high affinity and, therefore, can potentially reduce iron availability and oxidative activity. CFH levels are elevated over approximately 24-48 hours in our antibiotic-treated canine model of S. aureus pneumonia that simulates the cardiovascular abnormalities of human septic shock. In this 96-hour model, resuscitative treatments, …

Curriculum For Neurogastroenterology And Motility Training: A Report From The Joint Anms-Esnm Task Force, C P Gyawali, Et Al

Open Access Publications

Although neurogastroenterology and motility (NGM) disorders are some of the most frequent disorders encountered by practicing gastroenterologists, a structured competency-based training curriculum developed by NGM experts is lacking. The American Neurogastroenterology and Motility Society (ANMS) and the European Society of Neurogastroenterology and Motility (ESNM) jointly evaluated the components of NGM training in North America and Europe. Eleven training domains were identified within NGM, consisting of functional gastrointestinal disorders, visceral hypersensitivity and pain pathways, motor disorders within anatomic areas (esophagus, stomach, small bowel and colon, anorectum), mucosal disorders (gastro-esophageal reflux disease, other mucosal disorders), consequences of systemic disease, consequences of therapy …

Hepatic Tristetraprolin Promotes Insulin Resistance Through Rna Destabilization Of Fgf21, Konrad T. Sawicki, Hsiang-Chun Chang, Jason S. Shapiro, Marina Bayeva, Adam De Jesus, Brian N. Finck, Jason A. Wertheim, Perry J. Blackshear, Hossein Ardehali

Open Access Publications

The role of posttranscriptional metabolic gene regulatory programs in diabetes is not well understood. Here, we show that the RNA-binding protein tristetraprolin (TTP) is reduced in the livers of diabetic mice and humans and is transcriptionally induced in response to insulin treatment in murine livers in vitro and in vivo. Liver-specific Ttp-KO (lsTtp-KO) mice challenged with high-fat diet (HFD) have improved glucose tolerance and peripheral insulin sensitivity compared with littermate controls. Analysis of secreted hepatic factors demonstrated that fibroblast growth factor 21 (FGF21) is posttranscriptionally repressed by TTP. Consistent with increased FGF21, lsTtp-KO mice fed HFD have increased brown fat …

Epigenomics And Metabolomics Reveal The Mechanism Of The Apoa2-Saturated Fat Intake Interaction Affecting Obesity, Chao-Qiang Lai, Caren E Smith, Laurence D Parnell, Yu-Chi Lee, Dolores Corella, Paul Hopkins, Bertha A Hidalgo, Stella Aslibekyan, Michael A Province, Devin Absher, Donna K Arnett, Katherine L Tucker, Jose M Ordovas

Open Access Publications

Background: The putative functional variant -265T>C (rs5082) within the APOA2 promoter has shown consistent interactions with saturated fatty acid (SFA) intake to influence the risk of obesity.

Objective: The aim of this study was to implement an integrative approach to characterize the molecular basis of this interaction.

Design: We conducted an epigenome-wide scan on 80 participants carrying either the rs5082 CC or TT genotypes and consuming either a low-SFA (<22 g/d) or high-SFA diet (≥22 g/d), matched for age, sex, BMI, and diabetes status in the Boston Puerto Rican Health Study (BPRHS). We then validated the findings in selected participants in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) Study (n = 379) and the Framingham Heart Study (FHS) (n = 243). Transcription and metabolomics analyses were conducted to determine the relation between epigenetic status, APOA2 mRNA expression, and blood metabolites.

Results: In the BPRHS, we identified methylation site cg04436964 as exhibiting significant differences between CC and TT participants consuming a high-SFA diet, but not among those consuming low-SFA. Similar …

Validation Of A Novel Scoring System For Changes In Skeletal Manifestations Of Hypophosphatasia In Newborns, Infants, And Children: The Radiographic Global Impression Of Change Scale, Michael P Whyte, Kenji P Fujita, Scott Moseley, David D Thompson, William H Mcalister

Open Access Publications

Hypophosphatasia (HPP) is the heritable metabolic disease characterized by impaired skeletal mineralization due to low activity of the tissue-nonspecific isoenzyme of alkaline phosphatase. Although HPP during growth often manifests with distinctive radiographic skeletal features, no validated method was available to quantify them, including changes over time. We created the Radiographic Global Impression of Change (RGI-C) scale to assess changes in the skeletal burden of pediatric HPP. Site-specific pairs of radiographs of newborns, infants, and children with HPP from three clinical studies of asfotase alfa, an enzyme replacement therapy for HPP, were obtained at baseline and during treatment. Each pair was …

Building Capacity For Evidence-Based Public Health: Reconciling The Pulls Of Practice And The Push Of Research, Ross C Brownson, Jonathan E Fielding, Lawrence W Green

Open Access Publications

Timely implementation of principles of evidence-based public health (EBPH) is critical for bridging the gap between discovery of new knowledge and its application. Public health organizations need sufficient capacity (the availability of resources, structures, and workforce to plan, deliver, and evaluate the preventive dose of an evidence-based intervention) to move science to practice. We review principles of EBPH, the importance of capacity building to advance evidence-based approaches, promising approaches for capacity building, and future areas for research and practice. Although there is general agreement among practitioners and scientists on the importance of EBPH, there is less clarity on the definition …

Physiological Mechanisms Of Sustained Fumagillin-Induced Weight Loss, Jie An, Michael L Patnode, Vanessa K Ridaura, Jeffrey I Gordon, Et Al

Open Access Publications

Current obesity interventions suffer from lack of durable effects and undesirable complications. Fumagillin, an inhibitor of methionine aminopeptidase-2, causes weight loss by reducing food intake, but with effects on weight that are superior to pair-feeding. Here, we show that feeding of rats on a high-fat diet supplemented with fumagillin (HF/FG) suppresses the aggressive feeding observed in pair-fed controls (HF/PF) and alters expression of circadian genes relative to the HF/PF group. Multiple indices of reduced energy expenditure are observed in HF/FG but not HF/PF rats. HF/FG rats also exhibit changes in gut hormones linked to food intake, increased energy harvest by …

Results Of Asertaa, A Randomized Prospective Crossover Pharmacogenetic Study Of Immediate-Release Versus Extended-Release Tacrolimus In African American Kidney Transplant Recipients, Jennifer Trofe-Clark, Daniel C Brennan, Patricia West-Thielke, Michael C Milone, Mary Ann Lim, Robin Neubauer, Vincenza Nigro, Roy D Bloom

Open Access Publications

BACKGROUND: Differences in tacrolimus dosing across ancestries is partly attributable to polymorphisms in CYP3A5 genes that encode tacrolimus-metabolizing cytochrome P450 3A5 enzymes. The CYP3A5*1 allele, preponderant in African Americans, is associated with rapid metabolism, subtherapeutic concentrations, and higher dose requirements for tacrolimus, all contributing to worse outcomes. Little is known about the relationship between CYP3A5 genotype and the tacrolimus pharmacokinetic area under the curve (AUC) profile in African Americans or whether pharmacogenetic differences exist between conventional twice-daily, rapidly absorbed, immediate-release tacrolimus (IR-Tac) and once-daily extended-release tacrolimus (LifeCycle Pharma Tac [LCPT]) with a delayed absorption profile.

STUDY DESIGN: Randomized prospective crossover …
