In vitro inhibitory activity on RANKL-mediated osteoclastogenesis of Glossogyne tenuifolia extract

Wang Shih-Wei , Kuo Han-Chun , Hsu Hsia-Fen , Tu Yuan-Kun , Cheng Tien-Tsai , Houng Jer-Yiing

Receptor activator of nuclear factor kappa B ligand (RANKL)-induced activation of NF-κB and MAPKs signaling pathways is critical to osteoclastogenesis. Glossogyne tenuifolia has been used as an antipyretic, detoxication, and anti-inflammatory herb tea in Penghu Island, Taiwan. This study investigated the effects of G. tenuifolia ethanolic extract (GTE) on the formation of RANKL-activating osteoclasts and expression of signaling pathways using a RAW264.7 ...

Moderate hypothermia induces growth arrest in normal human osteoblast cells but retained mitochondrial metabolism in vitro

Ablation of osteosarcoma cells by sublethal hypothermia before radiation may increase sarcoma tissue sensitivity by inducing growth arrest. Normal cells that are not lethally damaged by hypothermia and radiation can undergo DNA repair thus promoting cell survival. Nevertheless, understanding of the response of normal bone forming osteoblast cells towards hypothermia is necessary before administering on osteosarcoma cells. In this study we evaluated the response of short-term m...

Background: We identified a family with early onset X-linked osteoporosis and fracturesMethods: We performed whole exome sequencing of the X chromosome in three affected members. After discovering a putative pathogenic variant we performed Sanger sequencing of all exons of this gene in other members of this family and in 95 unrelated men suspected of OI type I without COL1A1/2 mutations. We also genotyped a SNP in this gene (minor allele frequency 0.02) ...

Regulation of bone metastasis by the IKKβ/FoxO3a axis

Marino Silvia , Logan John G. , Sophocleous Antonia , Mollat Patrick , Mognetti Barbara , Ventura Luca , Sims Andrew H. , Rucci Nadia , Ralston Stuart H. , Idris Aymen I.

IκB Kinase β (IKKβ), a key component of NFκB signaling, plays an important role in bone disease and cancer. Genetic and pharmacological inhibition of IKKβ/NFκB signaling increase bone mass and protect against ovariectomy- and inflammation-induced bone loss. Here, we describe a previously unknown role of the IKKβ/FoxO3a axis in bone metastasis associated with breast cancer. We observed that IKKβ expression is prevalent in invasive breast ...

Infantile Blount's disease: histopathologic changes in the proximal tibial metaphysis -- comparison between medial and lateral specimens

Hollman Freek , Vroemen Pascal , Rompa Paul , Moh Prosper , van Rhijn Lodewijk , Weltink Tim , Staal Heleen

Only minor literature on histopathologic changes in Blount’s disease is available. This study presents the histologic findings of biopsies harvested from the medial and lateral part of the proximal tibia during the W/M serrated osteotomy in patients with infantile Blount’s disease, performed in Ghana. In this study it is hypothesized that the medial metaphyseal area in these children will present a different histological morphology compared to the lateral metaphyseal...

Stature and body weight more than age explain functionality level in children with Osteogenesis Imperfecta

Claudio de Castro Luiz , De David Ana , Coelho Giovana , Coccato Livia

Objective: The purpose of this study was to verify the influence of age, body mass and stature on the functionality level of children with Osteogenesis Imperfecta (OI). METHODS: Thirty-eight children (8.21±4.26 years, 19 girls and 52.6% OI type III) were evaluated during their hospitalization for Pamidronate intravenous infusion in the Brazilian Midwest reference hospital for OI treatment (University Hospital of Brasília). Body weight and stature were measured and ca...

Bone mineral density and trabecular bone score in ukrainian women with obesity

Povoroznyuk Vladyslav , Dzerovych Nataliia , Martynyuk Larysa , Kovtun Tetiana

The aim of this study was to evaluate the bone mineral density (BMD), trabecular bone score (TBS) in the Ukrainian women with obesity.Materials and methods: 1025 women aged 40–89 years (mean age – 62.7±9.7 yrs; mean height – 161.4±6.2 cm; mean weight – 73.9±13.8 kg, body mass index – 28.4±5.1 kg/m2) were examined. The women were divided into the following groups depending on their body mass index: A...

Are there gender differences in abdominal fat distribution in healthy teenagers?

Duboeuf Francois , Boutroy Stephanie , Ginhoux Tiphanie , Roux Jean-Paul , Chapurlat Roland , Bacchetta Justine

Background: While the relationship between visceral (VFAT) and subcutaneous (SFAT) fat mass with cardiometabolic risk has been demonstrated in adults, fat mass evolution during teenagehood remains poorly explored and usually assessed with irradiative (CT) or expensive (MRI) techniques. Our aim was to evaluate a novel technique derived from DXA to assess VFAT and SFAT in healthy teenagers.Subjects and methods: Healthy teenagers from the VITADOS study unde...

Normal human osteoblast cells exerts an adaptive effect towards moderate hypothermia by retaining bone metabolism and cellular function in vitro

Aisha Mohd Din , Nor-Ashikin Mohamed Noor Khan , Sharaniza Ab. Rahim , Nawawi Hapizah , Kapitonova Marina , Froemming Gabriele Ruth Anisah

Over the years, it has been demonstrated that the ability to maintain body core temperature in older adult’s declines with age. Temperature is a vital physical factor for cell growth and a downshift in core body temperature (<37 °C) might have a direct affect on maintaining bone density or repair fractures. Disruption in any of the cellular processes involved in bone remodelling leads to a net loss of bone mineral density and bone loss. Therefore our study looked...
