Heme oxygenase-1 (HO-1) has long been considered to be an endogenous antioxidant. However, the role of HO-1 is highly controversial in developing metabolic diseases. We hypothesized that HO-1 plays a role in maintaining bone mass by alleviating a redox imbalance. We investigated its role in bone remodeling. The absence of HO-1 in mice led to decreased bone(More)
Blood clotting is initiated by the two-subunit enzyme consisting of the plasma protease, factor VIIa (the catalytic subunit), bound to the integral membrane protein, tissue factor (the regulatory subunit). Molecular dynamics simulations have predicted that certain residues in the tissue factor ectodomain interact with phosphatidylserine headgroups to ensure(More)
BACKGROUND Cilostazol has been reported to alleviate the metabolic syndrome induced by increased intracellular adenosine 3',5'-cyclic monophosphate (cAMP) levels, which is also associated with osteoclast (OC) differentiation. We hypothesized that bone loss might be attenuated via an action on OC by cilostazol. METHODOLOGY AND PRINCIPAL FINDINGS To test(More)
Loss of ovarian function causes oxidative stress as well as bone loss. We hypothesized that reactive oxygen species (ROS) induced by the failure of ovarian function are responsible for the bone loss by increasing the number of osteoclasts (OC). We found that ROS enhanced OC survival via Src homology 2 domain-containing phosphatase-1 (SHP-1), c-Src, Akt, and(More)
BACKGROUND Tranilast (N-(3',4'-dimethoxycinnamonyl) anthranilic acid) has been shown to be therapeutically effective, exerting anti-inflammatory and anti-oxidative effects via acting on macrophage. We hypothesized that Tranilast may protect against oxidative stress-induced bone loss via action in osteoclasts (OCs) that shares precursors with macrophage. (More)
Web services choreography describes the global model of service interactions among a set of participants. In order to achieve a common business goal, the protocols for interactions must be correct. Experiences show that it is difficult to check choreography manually, even it is not very complex. A scenario describes a sequence of interactions among the(More)
