A deficit in bone formation is a major factor in diabetes-related osteopenia. We examined here whether diabetes-associated changes in osteoblast phenotype might in part result from a decrease in PTH-related protein (PTHrP). We used a bone marrow ablation model in diabetic mice by multiple streptozotocin injections. PTHrP (1-36) (100 microg/kg, every other(More)
Parathyroid hormone-related protein (PTHrP) (107-139), in contrast to the N-terminal fragment PTHrP (1-36), has been shown to interact with the vascular endothelial growth factor (VEGF) system to modulate human osteoblast differentiation. In this study, we evaluated whether this interaction might affect human osteoblastic cell survival. Pre-incubation with(More)
The Notch signalling pathway plays an essential role in the intricate control of cell proliferation and pattern formation in many organs during animal development. In addition, mutations in most members of this pathway are well characterized and frequently lead to tumour formation. The Drosophila imaginal wing discs have provided a suitable model system for(More)
One of the major issues in developmental biology is about having a better understanding of the mechanisms that regulate organ growth. Identifying these mechanisms is essential to understand the development processes that occur both in physiological and pathological conditions, such as cancer. The E protein family of basic helix-loop helix (bHLH)(More)
