Evidence of intrauterine growth restriction and growth hormone deficiency in 49,XXXXY syndrome.

Am J Med Genet A 2020 Jul 2. Epub 2020 Jul 2.

Division of Research, The Focus Foundation, Davidsonville, Maryland, USA.

49,XXXXY is an X and Y chromosome variation that occurs in 1:85,000 to 1:100,000 live male births. Previous case studies have described boys with this disorder to be shorter than average when compared with boys with only one extra chromosome and with the mean stature in a small cohort reported to range from the seventh to 33rd percentile. The origin behind the possible differences in height between boys with 47,XXY and 49,XXXXY is currently unknown, however one study hypothesized that it was due to a difference in the expression of the SHOX gene.

Low bone mineral density due to secondary hyperparathyroidism in the mouse model of Fabry disease.

FASEB Bioadv 2020 Jun 10;2(6):365-381. Epub 2020 Jun 10.

Department of Matrix Medicine Faculty of Medicine Oita University Yufu Oita Japan.

Low bone mineral density (BMD)-diagnosed as osteoporosis or osteopenia-has been reported as a new characteristic feature of Fabry disease; however, the mechanism underlying the development of low BMD is unknown. We previously revealed that a mouse model of Fabry disease [] exhibits impaired functioning of medullary thick ascending limb (mTAL), leading to insufficient Ca reabsorption and hypercalciuria. Here, we investigated bone metabolism in mice without marked glomerular or proximal tubular damage. Read More

The Severity of Growth Hormone Deficiency Does Not Predict the Presence or Absence of Brain Magnetic Resonance Imaging Abnormalities - A Retrospective Review.

Eur Endocrinol 2020 Apr 5;16(1):60-64. Epub 2020 Feb 5.

Department of Endocrinology, Children's Mercy Hospital, University of Missouri-Kansas City (UMKC), Kansas City, MO, USA.

Background: The Growth Hormone Research Society recommends that all patients diagnosed with growth hormone deficiency (GHD) should undergo brain magnetic resonance imaging (MRI). This is still a point of controversy in patients with mild GHD, as the level of peak growth-hormone (GH) as a predictor of brain MRI abnormality has not yet been established. The objective of this study was to determine if peak GH level, determined by stimulation tests, can predict the presence or absence of brain MRI abnormality. Read More

Dual Role of Gibberellin in Perennial Shoot Branching: Inhibition and Activation.

Front Plant Sci 2020 5;11:736. Epub 2020 Jun 5.

Department of Plant Sciences, Norwegian University of Life Sciences, Ås, Norway.

Shoot branching from axillary buds (AXBs) is regulated by a network of inhibitory and promotive forces, which includes hormones. In perennials, the dwarfed stature of the embryonic shoot inside AXBs is indicative of gibberellin (GA) deficiency, suggesting that AXB activation and outgrowth require GA. Nonetheless, the role of GA in branching has remained obscure. Read More

Early versus late initiation of GH replacement in adult-onset hypopituitarism.

Endocr Connect 2020 Jun 1. Epub 2020 Jun 1.

A van Beek, Department of Endocrinology, University Medical Center Groningen, Groningen, Netherlands.

Introduction: Adult-onset growth hormone deficiency (AGHD) is usually the last deficiency to be substituted in hypopituitarism. In children with documented GH deficiency, treatment without delay is crucial for achieving optimal effects on growth and development. In adults, it is not known whether a delay in treatment initiation influences biochemical response and the favourable physiological effects resulting from GH replacement therapy (GHRT). Read More

Growth hormone therapy in children with partial growth hormone deficiency. Are we treating the right patients?

Pediatr Endocrinol Diabetes Metab 2020 ;26(2):65-72

Department of Paediatrics and Paediatric Endocrinology, School of Medicine in Katowice, Medical University of Silesia, Poland.

Introduction: Diagnosis of growth hormone deficiency (GHD) in children with short stature, whose height is below -2SD for the population norm, is based on the assessment of growth hormone (GH) peaks in stimulation tests. However, cut-off values for GH secretion are arbitrary and vary in different centres. Indications for recombinant GH therapy remain disputable in children with GH concentrations between 5 and 10 ng/ml (pGHD). Read More

National Institute of Plant Genome Research, Aruna Asaf Ali Marg, New Delhi, 110067, India. Electronic address:

Brassinosteroids (BRs) are well-characterized growth hormones that are critical for plant growth, development, and productivity. Genetic and molecular studies have revealed the key components of BR biosynthesis and signaling pathways. The membrane-localized BR signaling receptor, BRASSINOSTEROID INSENSITIVE1 (BRI1) binds directly to its ligand and initiates series of signaling events that led to the activation of BR transcriptional regulators, BRASSINAZOLE RESISTANT1 (BZR1) and BRI1-ETHYL METHANESULFONATE-SUPPRESSOR1 (BES1/BZR2) to regulate the cellular processes.

Do Phosphate and Cytokinin Interact to Regulate Strigolactone Biosynthesis or Act Independently?

Front Plant Sci 2020 20;11:438. Epub 2020 May 20.

Center for Bioscience Research and Education, Utsunomiya University, Utsunomiya, Japan.

Strigolactones (SLs) are essential host recognition signals for both root-parasitic plants and arbuscular mycorrhizal (AM) fungi in the rhizosphere, and SLs or their metabolites function as a novel class of plant hormones that regulate various aspects of plant growth through crosstalk with other hormones. Although nutrient availability is one of the important factors influencing SL production and exudation, and phosphate (Pi) deficiency significantly promotes SL production and exudation in host plants of AM fungi, how nutrient availability modulates SL production and exudation remains elusive. Cytokinin (CK), a canonical plant hormone, has extensively been studied as a shoot branching promoter and its biosynthesis is also influenced by mineral nutrients, especially nitrate, indicating that CK might be another key factor that affect SL production and exudation.

Besides its effects on longitudinal growth in childhood and its metabolic effects with consequences on body composition and lipid levels, growth hormone (GH) has important roles on maintaining the structure and function of the normal adult heart. GH/insulin like growth factor-I (IGF-I) also interacts with the vascular system and plays a role in the regulation of vascular tone. GH deficiency (GHD) in adulthood is associated with increased fat mass (particularly visceral) and abnormal lipid profile, which may contribute to the excess cardiovascular mortality observed in patients with panhypopituitarism.

Male Gonadal Function after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood: A Cross-Sectional, Population-Based Study.

Biol Blood Marrow Transplant 2020 May 21. Epub 2020 May 21.

Division of Hematology-Oncology and Stem Cell Transplantation, Children's Hospital, University of Helsinki and Helsinki University Hospital, Helsinki, Finland; Pediatric Endocrinology Unit, Department of Women's and Children's Health, Karolinska Institute and University Hospital, Stockholm, Sweden. Electronic address:

Male gonadal dysfunction is a frequent late effect after pediatric hematopoietic stem cell transplantation (HSCT), but detailed insight into patterns of male gonadal function at long-term is limited by retrospective studies without semen sample data. In this study, we investigated the risk of azoospermia and testosterone deficiency, the diagnostic value of markers of spermatogenesis, and paternity at long-term follow-up after pediatric allogeneic HSCT. All male HSCT survivors age ≥18 years, transplanted in Denmark or Finland between 1980 and 2010, were invited to participate in this cross-sectional study. Read More

Motivation for and adherence to growth hormone replacement therapy in adults with hypopituitarism: the patients' perspective.

Pituitary 2020 May 21. Epub 2020 May 21.

Department of Endocrinology, Diabetes and Nutritional Medicine, Campus Charité Mitte, Charité Universitaetsmedizin, Charitéplatz 1, 10117, Berlin, Germany.

Introduction: While reasons for non-adherence in children requiring growth hormone (GH) replacement (GH-Rx) are well researched, few studies have investigated adherence in adult GH deficient patients. Against the background of the adverse medical sequelae of untreated severe GH deficiency (GHD) in adults, we explored adherence to GH-Rx and associated factors in this patient group.

Method: Cross-sectional analysis including 107 adult patients with severe GHD on GH-Rx, 15 untreated GDH patients and 19 who had discontinued therapy. Read More

Sex-biased genetic programs in liver metabolism and liver fibrosis are controlled by EZH1 and EZH2.

PLoS Genet 2020 May 19;16(5):e1008796. Epub 2020 May 19.

Department of Biology and Bioinformatics Program, Boston University, Boston, Massachusetts, United States of America.

Sex differences in the incidence and progression of many liver diseases, including liver fibrosis and hepatocellular carcinoma, are associated with sex-biased hepatic expression of hundreds of genes. This sexual dimorphism is largely determined by the sex-specific pattern of pituitary growth hormone secretion, which controls a transcriptional regulatory network operative in the context of sex-biased and growth hormone-regulated chromatin states. Histone H3K27-trimethylation yields a major sex-biased repressive chromatin mark deposited at many strongly female-biased genes in male mouse liver, but not at male-biased genes in female liver, and is catalyzed by polycomb repressive complex-2 through its homologous catalytic subunits, Ezh1 and Ezh2.

Physiological and metabolic features of mice with CRISPR/Cas9-mediated loss-of-function in growth hormone-releasing hormone.

Aging (Albany NY) 2020 May 18;12(10):9761-9780. Epub 2020 May 18.

Department of Biology, University of Alabama at Birmingham, Birmingham, AL 35233, USA.

Our previous study demonstrated that the loss of growth hormone releasing hormone (GHRH) results in increased lifespan and improved metabolic homeostasis in the mouse model generated by classical embryonic stem cell-based gene-targeting method. In this study, we targeted the GHRH gene using the CRISPR/Cas9 technology to avoid passenger alleles/mutations and performed in-depth physiological and metabolic characterization. In agreement with our previous observations, male and female GHRH mice have significantly reduced body weight and enhanced insulin sensitivity when compared to wild type littermates. Read More
