| dc.description.abstract | Vanadate, one of the most relevant forms of vanadium in solution, has been associated with the regulation of various enzyme activities (e.g. phosphatases, ribonucleases, ATPases, etc.) and shown to exhibit important biological effects. Several in vivo and in vitro studies have clearly demonstrated that any deficiency or excess of vanadium can seriously affect bone formation and its metabolism. Bone-related effects result largely from vanadium insulino-mimetic capabilities mediated by specific inhibition of protein tyrosine phosphatases (PTPases) and consequent activation of tyrosine kinase receptors (e.g. insulin receptor). Although mammals have been repetitively shown to be appropriate models to study vanadate mechanisms of action, fish have recently emerged as alternative models. Fish has been recognized as suitable model to study vertebrate bone formation and the natural presence of high quantities of vanadium in water makes it even more suitable to investigate vanadium effect on bone formation. Recent data obtained using fish bone-derived cells revealed that micromolar concentrations (5 mM) of monomeric and decameric vanadate slightly stimulate growth performances while strongly inhibiting extracellular matrix mineralization through mechanisms involving both alkaline phosphatase and MAPK pathways. Recent data obtained in fish cells will be discussed here and further compared to results obtained in mammalian systems. | por |
