Platinum nanoparticles have shown to have a remarkable antioxidant activity. Growing evidence between oxidative stress and bone loss suggests that platinum nanoparticle could protect bone loss via modulating oxidative stress. Intragastrical administration of platinum nanoparticle reduced ovariectomy (OVX)-induced bone loss with lowered level of in vivo bone resorption. Platinum nanoparticle inhibited osteoclast (OC) formation via an impaired receptor activator of nuclea...

Osterix (Osx) is an essential transcription factor for osteoblast differentiation and bone formation. Osx null mutants died perinatally with a complete absence of bone formation and Osx conditional knockouts in osteoblasts showed the osteopenic phenotype after birth. Even in Osx heterozygous mice with normal bone morphology, the reduced cortical thickness and osteoblast differentiation were observed by QCT and in vitro cell culture, respectively. This result exhibited t...

Aim: Patients with type 2 diabetes (T2DM) have increased risk of cardiovascular disease (CVD) including stroke. The risk of CVD is traditionally assessed using office blood pressure (BP) and lipid profile. Increased arterial stiffness predicts cardiovascular events in the general population. We investigated if arterial stiffness was associated with cerebrovascular disease in patients with T2DM and sex- and age-matched controls indepentl y of classical risk factors.<p class...

PTTG binding factor (PBF) is a poorly characterised 22 kDa protein that is implicated in the aetiology of pituitary and thyroid tumours. Our recent investigations have attempted to discern the function of PBF in vitro. In particular, we reported that PBF can inhibit the activity of the sodium iodide symporter (NIS), which is responsible for iodide uptake into thyroid cells. However, little is known about the precise role of PBF in vivo. We have now generated a mu...
