Rutin, a glycoside of flavonol, inhibits osteoclast formation induced by receptor activator of NF-kappaB ligand (RANKL) in bone marrow-derived macrophages. It reduces reactive oxygen species produced by RANKL and its inhibitory effect results from reduced levels of TNF-alpha. Rutin also lowers NF-kappaB activation in response to RANKL.

Introduction: is a medicinal plant that produces silymarin, which has been demonstrated to possess antiviral, anti-neurodegenerative, and anticancer activities. Silybin (A+B) are two major hepatoprotective flavonolignans produced predominantly in fruits. Several attempts have been made to increase the synthesis of silymarin, or its primary components, silybin (A+B).

Reproductive hormones associated with the hypothalamic-pituitary-gonadal (HPG) axis are closely linked to bone homeostasis. In this study, we demonstrate that Gonadotropin inhibitory hormone (GnIH, one of the key reproductive hormones upstream of the HPG axis) plays an indispensable role in regulating bone homeostasis and maintaining bone mass. We find that deficiency of GnIH or its receptor Gpr147 leads to a significant reduction in bone mineral density (BMD) in mice primarily by enhancement of osteoclast activation in vivo and in vitro.

BDE-209 has a causal relationship with adverse health outcomes. However, research on its effect on bone homeostasis is relatively lacking. This study examined the relationship between BDE-209 exposure and bone health, as well as the underlying mechanisms, using both in vitro and in vivo models.

Tooth eruption as a crucial part in tooth development and regeneration is accompanied by ongoing osteogenesis and osteoclast activity. The dental follicle (DF) surrounding the developing tooth harbors dental follicle stem cells (DFSCs) which play a crucial role in maintaining bone remodeling. However, the mechanisms through which they regulate the balance between osteogenesis and osteoclast activity during tooth eruption remain poorly understood.

Objective: Relapse after orthodontic treatment remains a crucial problem. Pulsed electromagnetic fields (PEMFs) accelerate osteoblastogenesis and inhibit osteoclastogenesis. However, their effect on tooth movement during the retention phase of orthodontic treatment has not been studied.
