Effects of glucagon-like peptide-1 receptor agonists on bone blow flow and architecture in diabetic mice

Pereira Marie , Gohin Stephanie , Cleasby Mark , Chenu Chantal

Type 2 diabetes mellitus prevalence increases with age and the disease predisposes to increased risk of fractures and skeletal complications. One possible contributor to skeletal weakening in diabetes is a decline in blood supply. We hypothesised that bone blood flow is impaired in diabetic mice and that chronic administration of glucagon-like peptide-1 receptor agonists (GLP-1RA) can increase blood flow to bone, thereby stimulating bone formation and improving bone architectu...

Effect of melatonin on in vitro bone remodelling and blood supply

Gohin Stephanie , Pereira Marie , Belgrave Naomi Weekes , Lee Ji Sun , Tompkins Hayley , Orriss Isabel , Chenu Chantal

Melatonin is a neuro-hormone released primarily from the pineal gland, which has been shown to have bone anabolic effect, although it is still unclear whether its skeletal action is directly mediated by receptors expressed on bone cells or is indirect. In this study, we examined melatonin’s effects on bone cellular activities in vitro and tested whether it modifies angiogenesis and blood flow to bone, which are both essential for bone formation.<p class="abst...
