The neuro-hypophiseal hormone oxytocin (OT) is a novel anabolic regulator of bone mass (Tamma et al. PNAS, 2009), upregulating expression of critical osteoblast transcription factors. These effects are mediated by oxytocin receptor, a GPCR expressed by osteoblasts. Recently an increasing number of reports indicates that GPCRs could be targeted to the nuclear membrane; prostaglandin receptors, endothelin receptors and β-adrenergic receptors among others (...

Multiple myeloma (MM)-bone disease occurs in 70 to 80% of patients at MM diagnosis, and up to 90% at relapse; skeletal related events cause high morbidity and mortality. MM-bone disease consists of lytic lesions arising as a consequence of an unbalanced bone remodelling due to osteoclast (OC) activation, and osteoblast inactivation. Osteoclastogenesis may be under immune cell regulation through the production of numerous cytokines, such as LIGHT/TNFSF14, a newly identified mem...
