Progress in bone fracture repair research has been made possible due to the development of reproducible models of fracture in rodents with more clinically relevant fracture fixation, where there is considerably better assessment of the factors that a...

Fracture-induced pain-like behaviours in a femoral fracture mouse model (2021)
Journal Article

This study is the first comprehensive characterisation of the pain phenotype after fracture using both evoked and naturalistic behaviours in adult male and ovariectomised female mice. It also shows that an anti-nerve growth factor (NGF) therapy could... Read More about Fracture-induced pain-like behaviours in a femoral fracture mouse model.

Applied mechanical loading to mouse hindlimb acutely increases skeletal perfusion and chronically enhanced vascular porosity (2020)
Journal Article
Gohin, S., Javaheri, B., Hopkinson, M., Pitsillides, A. A., Arnett, T. R., & Chenu, C. (2020). Applied mechanical loading to mouse hindlimb acutely increases skeletal perfusion and chronically enhanced vascular porosity. Journal of Applied Physiology,

Blood supply is essential for osteogenesis, yet its relationship to load-related increases in bone mass is poorly defined. Herein, we aim to investigate the link between load-induced osteogenesis and the blood supply (bone perfusion and vascular poro...

Osteoarthritis-related nociceptive behaviour following mechanical joint loading correlates with cartilage damage (2020)
Journal Article
Ter Heegde, F., Luiz, A. P., Santana-Varela, S., Magnusdottir, R., Hopkinson, M., Chang, Y. M., …Chenu, C. (2020). Osteoarthritis-related nociceptive behaviour following mechanical joint loading correlates with cartilage damage. Osteoarthritis and Cartilage, 28(3), 383-395. https://doi.org/10.1016/j.joca.2019.12.004

In osteoarthritis (OA), the pain-structure relationship remains complex and poorly understood. Here, we used the mechanical joint loading (MJL) model of OA to investigate both knee pathology and nociceptive behaviour.

Bidirectional regulation of bone formation by exogenous and osteosarcoma-derived Sema3A (2018)
Journal Article
De Ridder, D., Marino, S., Bishop, R. T., Renema, N., Chenu, C., Heymann, D., & Idris, A. I. (2018). Bidirectional regulation of bone formation by exogenous and osteosarcoma-derived Sema3A. https://doi.org/10.1038/s41598-018-25290-2

Semaphorin 3A (Sema3A), a secreted member of the Semaphorin family, increases osteoblast differentiation, stimulates bone formation and enhances fracture healing. Here, we report a previously unknown role of Sema3A in the regulation of ectopic bone f... Read More about Bidirectional regulation of bone formation by exogenous and osteosarcoma-derived Sema3A.

Novel skeletal effects of glucagon-like peptide-1 (GLP-1) receptor agonists (2018)
Journal Article

Type 2 diabetes mellitus (T2DM) leads to bone fragility and predisposes to increased risk of fracture, poor bone healing and other skeletal complications. In addition, some anti-diabetic therapies for T2DM can have notable detrimental skeletal effect... Read More about Novel skeletal effects of glucagon-like peptide-1 (GLP-1) receptor agonists.

Exenatide Improves Bone Quality in a Murine Model of Genetically Inherited Type 2 Diabetes Mellitus (2017)
Journal Article

Type 2 diabetes mellitus (T2DM) is associated with skeletal complications, including an increased risk of fractures. Reduced blood supply and bone strength may contribute to this skeletal fragility. We hypothesized that long-term administration of... Read More about Exenatide Improves Bone Quality in a Murine Model of Genetically Inherited Type 2 Diabetes Mellitus.
