Expression of semaphorin-3A in the joint and role in osteoarthritis (2024)
Journal Article
Li, X., Martinez-Ramos, S., Heedge, F., Pitsillides, A., Bou-Gharios, G., Poulet, B., & Chenu, C. (2024). Expression of semaphorin-3A in the joint and role in osteoarthritis. Cell Biochemistry and Function, 42(3), https://doi.org/10.1002/cbf.4012

Osteoarthritis (OA) is characterised by the deterioration of cartilage in the joints and pain. We hypothesise that semaphorin-3A (sema-3A), a chemorepellent for sensory nerves, plays a role in joint degradation and pain. We used the mechanical joint...

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

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., Poulet, B., Fowkes, R. C., Wood, J. N., & 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

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)
