P38 mitogen-activated protein kinase inhibitor, FR167653, inhibits parathyroid hormone related protein-induced osteoclastogenesis and bone resorption. [PDF]

open access: yesPLoS ONE, 2011
p38 mitogen-activated protein kinase (MAPK) acts downstream in the signaling pathway that includes receptor activator of NF-κB (RANK), a powerful inducer of osteoclast formation and activation.

Nobiletin, a Polymethoxy Flavonoid, Suppresses Bone Resorption by Inhibiting NFκB-Dependent Prostaglandin E Synthesis in Osteoblasts and Prevents Bone Loss Due to Estrogen Deficiency

open access: yesJournal of Pharmacological Sciences, 2011
Nobiletin, a polymethoxy flavonoid, prevents cancer and inflammation, but the roles of nobiletin in bone are unclear. We examined the effects of nobiletin on bone resorption in vitro and on bone mass in ovariectomized (OVX) mice in vivo.

Bone Resorption by Osteocytes

open access: yesExperimental Biology and Medicine, 1968
SummaryOsteocyte lacunae were measured in normal rats and in rats in which periosteal hypertrophy had been induced at the adductor longus-pectineus insertion. Lacunae in the cortex beneath the periosteal hypertrophy were significantly larger than lacunae in the cortex of the opposite side of the femur from the hypertrophy.

ELMO1 Regulates RANKL-Stimulated Differentiation and Bone Resorption of Osteoclasts

open access: yesFrontiers in Cell and Developmental Biology, 2021
Bone homeostasis is a metabolic balance between the new bone formation by osteoblasts and old bone resorption by osteoclasts. Excessive osteoclastic bone resorption results in low bone mass, which is the major cause of bone diseases such as rheumatoid ...

The Role of Bone and Root Resorption on the Biomechanical Behavior of Mandibular Anterior Teeth Subjected to Orthodontic Forces: A Finite Element Approach

open access: yesBiomedicines
Aims: This study was conducted to systematically evaluate the biomechanical impact of varying degrees of root and bone resorption resulting from periodontitis and orthodontic tooth movement (OTM) on the mandibular anterior teeth.

Pharmacological Topics of Bone Metabolism: The Physiological Function of the Sympathetic Nervous System in Modulating Bone Resorption

open access: yesJournal of Pharmacological Sciences, 2008
The vertebrate skeleton is richly innervated with adrenergic and peptidergic nerve terminals, and these play important roles in bone remodeling. Recent studies have generally shown that increased sympathetic nervous activity causes bone loss via an ...

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Osteoclast biology in bone resorption: a review

open access: yesSTEMedicine, 2020
What we know about bone resorption has changed a lot in the last few decades. The osteoclast is the only cell to nibble and break down the bone, and in the formation and resorption of bone tissue, osteoclasts play an important role.

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...
