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
Mabilleau, G., Pereira, M., & Chenu, C. (2018). Novel skeletal effects of glucagon-like peptide-1 (GLP-1) receptor agonists. Journal of Endocrinology, 236, R29-R42. https://doi.org/10.1530/JOE-17-0278

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
Pereira, M., Gohin, S., Roux, J., Fisher, A., Cleasby, M. E., Mabilleau, G., & Chenu, C. (2017). Exenatide Improves Bone Quality in a Murine Model of Genetically Inherited Type 2 Diabetes Mellitus. Frontiers in Endocrinology, 8(327), https://doi.org/10.3389/fendo.2017.00327

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.

Chronic administration of Glucagon-like peptide-1 receptor agonists improves trabecular bone mass and architecture in ovariectomised mice (2015)
Journal Article
Pereira, M., Jeyabalan, J., Jorgensen, C. S., Hopkinson, M., Al-Jazzar, A., Roux, J. P., …Chenu, C. (2015). Chronic administration of Glucagon-like peptide-1 receptor agonists improves trabecular bone mass and architecture in ovariectomised mice. BONE, 81, 459-67. https://doi.org/10.1016/j.bone.2015.08.006

Some anti-diabetic therapies can have adverse effects on bone health and increase fracture risk. In this study, we tested the skeletal effects of chronic administration of two Glucagon-like peptide-1 receptor agonists (GLP-1RA), increasingly used for...

Excessive growth hormone expression in male GH transgenic mice adversely alters bone architecture and mechanical strength (2015)
Journal Article
Lim, S., Marenzana, M., Hopkinson, M., List, E., Kopchick, J., Pereira, M., …Chenu, C. (2015). Excessive growth hormone expression in male GH transgenic mice adversely alters bone architecture and mechanical strength. Endocrinology, 156(4), 1362-1371. https://doi.org/10.1210/en.2014-1572

Patients with acromegaly have a higher prevalence of vertebral fractures despite normal bone mineral density (BMD), suggesting that GH overexpression has adverse effects on skeletal architecture and strength. We used giant bovine GH (bGH) transgenic... Read More about Excessive growth hormone expression in male GH transgenic mice adversely alters bone architecture and mechanical strength.

Low Dose of Propranolol Does Not Affect Rat Osteotomy Healing and Callus Strength (2014)
Journal Article
Smitham, P., Crossfield, L., Hughes, G., Goodship, A., Blunn, G., & Chenu, C. (2014). Low Dose of Propranolol Does Not Affect Rat Osteotomy Healing and Callus Strength. Journal of Orthopaedic Research, 32(7), 887-893. https://doi.org/10.1002/jor.22619

Experimental studies suggest that the β‐blocker propranolol stimulates bone formation but little work has investigated its effect on fracture healing. In this study, we examined if a low dose of propranolol, previously shown to be preventive against...
