An FDA-Approved Drug Screen for Compounds Influencing Craniofacial Skeletal Development and Craniosynostosis.

Mol Syndromol 2019 Feb 21;10(1-2):98-114. Epub 2018 Jul 21.

Genetics and Genomic Medicine, UCL Institute of Child Health, London, UK.

Neural crest stem/progenitor cells (NCSCs) populate a variety of tissues, and their dysregulation is implicated in several human diseases including craniosynostosis and neuroblastoma. We hypothesised that small molecules that inhibit NCSC induction or differentiation may represent potential therapeutically relevant drugs in these disorders. We screened 640 FDA-approved compounds currently in clinical use for other conditions to identify those which disrupt development of NCSC-derived skeletal elements that form the zebrafish jaw.

Medial unicompartmental knee arthroplasty: increasingly uniform patient demographics despite differences in surgical volume and usage-a descriptive study of 8,501 cases from the Danish Knee Arthroplasty Registry.

Acta Orthop 2019 Apr 11:1-10. Epub 2019 Apr 11.

a Department of Orthopaedic Surgery, Clinical Orthopaedic Research Hvidovre (CORH) , Copenhagen University Hospital Hvidovre , Denmark ;

Background and purpose - Using contemporary indications, up to 50% of patients undergoing knee arthroplasty are eligible for unicompartmental knee arthroplasty (UKA), and lower UKA use likely reflects a restrictive approach to patient selection. Since broader indications have been successfully introduced, and low surgical volume and UKA percentage (usage) are associated with higher revision rates, it is of interest whether the actual use of UKA has changed accordingly. We explored this by assessing time trends in patient demographics and whether these are associated with center UKA volume and usage. Read More

Exogenous Delivery of Link N mRNA into Chondrocytes and MSCs-The Potential Role in Increasing Anabolic Response.

Int J Mol Sci 2019 Apr 6;20(7). Epub 2019 Apr 6.

Department of Thoracic and Cardiovascular Surgery, University Hospital Tübingen, Calwerstraße 7/1, 72076 Tübingen, Germany.

Musculoskeletal disorders, such as osteoarthritis and intervertebral disc degeneration are causes of morbidity, which concomitantly burdens the health and social care systems worldwide, with massive costs. Link N peptide has recently been described as a novel anabolic stimulator for intervertebral disc repair. In this study, we analyzed the influence on anabolic response, by delivering synthetic Link N encoding mRNA into primary human chondrocytes and mesenchymal stromal cells (SCP1 cells), Furthermore, both cell types were seeded on knitted titanium scaffolds, and the influence of Link N peptide mRNA for possible tissue engineering applications was investigated.

MicroRNA-15a-5p Regulates the Development of Osteoarthritis by Targeting PTHrP in Chondrocytes.

Biomed Res Int 2019 5;2019:3904923. Epub 2019 Mar 5.

Department of Orthopedics, The Second Xiangya Hospital, Central South University, 139 Renmin Road, Changsha 410011, China.

Background And Aims: A growing body of research has demonstrated that the degeneration of chondrocytes is the primary cause of osteoarthritis (OA). Parathyroid hormone-related protein (PTHrP) can alleviate the degeneration of chondrocytes via promotion of chondrocyte proliferation and inhibition of terminal differentiation, but the underlying mechanism remains unknown. This study aimed to identify the microRNAs (miRNAs) that may target PTHrP and regulate the proliferation and terminal differentiation of chondrocytes. Read More

Senescence cell-associated extracellular vesicles serve as osteoarthritis disease and therapeutic markers.

JCI Insight 2019 Apr 4;4(7). Epub 2019 Apr 4.

Translational Tissue Engineering Center, Wilmer Eye Institute, and Department of Biomedical Engineering, Johns Hopkins University, Baltimore, Maryland, USA.

Senescent cells (SnCs) are increasingly recognized as central effector cells in age-related pathologies. Extracellular vesicles (EVs) are potential cellular communication tools through which SnCs exert central effector functions in the local tissue environment. To test this hypothesis in a medical indication that could be validated clinically, we evaluated EV production from SnCs enriched from chondrocytes isolated from human arthritic cartilage. Read More

Lixisenatide attenuates advanced glycation end products (AGEs)-induced degradation of extracellular matrix in human primary chondrocytes.

Artif Cells Nanomed Biotechnol 2019 Dec;47(1):1256-1264

a Department of Orthopaedics , The Second Hospital of Jilin University , Changchun , Jilin , China.

Osteoarthritis (OA) poses a growing threat to the health of the global population. Accumulation of advanced glycation end-products (AGEs) has been shown to upregulate expression of degradative enzymes such as matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) in chondrocytes, which leads to excessive degradation of type II collagen and aggrecan in the articular extracellular matrix (ECM). In the present study we investigated the effects of the GLP-1 agonist lixisenatide, a widely used type II diabetes medication, on AGEs-induced decreased mitochondrial membrane potential (MMP), degradation of ECM, oxidative stress, expression of cytokines including interleukin (IL)-1β and IL-6, and activation of nuclear factor kappa B (NF-κB).

Formononetin Antagonizes the Interleukin-1β-Induced Catabolic Effects Through Suppressing Inflammation in Primary Rat Chondrocytes.

Inflammation 2019 Apr 1. Epub 2019 Apr 1.

Oral Biology Research Institute, School of Dentistry, Chosun University, 309 Philmun-daero, Dong-gu, Gwangju, 61452, Republic of Korea.

In the present study, we demonstrated the anti-catabolic effects of formononetin, a phytoestrogen derived from herbal plants, against interleukin-1β (IL-1β)-induced severe catabolic effects in primary rat chondrocytes and articular cartilage. Formononetin did not affect the viability of primary rat chondrocytes in both short- (24 h) and long-term (21 days) treatment periods. Furthermore, formononetin effectively antagonized the IL-1β-induced catabolic effects including the decrease in proteoglycan content, suppression of pericellular matrix formation, and loss of proteoglycan through the decreased expression of cartilage-degrading enzymes like matrix metalloproteinase (MMP)-13, MMP-1, and MMP-3 in primary rat chondrocytes.
