ER Stress, the Unfolded Protein Response and Osteoclastogenesis: A Review

Biomolecules, 2023
Endoplasmic reticulum (ER) stress and its adaptive mechanism, the unfolded protein response (UPR), are triggered by the accumulation of unfolded and misfolded proteins. During osteoclastogenesis, a large number of active proteins are synthesized. When an

Porphyromonas gingivalis-derived extracellular vesicles aggravate bone destruction in rheumatoid arthritis by promoting Syk-dependent osteoclastogenesis [PDF]

International Journal of Oral Science
Rheumatoid arthritis (RA) is an autoimmune disorder that triggers progressive joint destruction by inducing excessive osteoclastogenesis. Porphyromonas gingivalis (Pg), the main pathogenic bacterium involved in periodontitis (PD), is closely related to ...

Semaphorin 4D Promotes Skeletal Metastasis in Breast Cancer. [PDF]

, 2016
Bone density is controlled by interactions between osteoclasts, which resorb bone, and osteoblasts, which deposit it. The semaphorins and their receptors, the plexins, originally shown to function in the immune system and to provide chemotactic cues for ...

Nox4 Promotes RANKL-Induced Autophagy and Osteoclastogenesis via Activating ROS/PERK/eIF-2α/ATF4 Pathway

Frontiers in Pharmacology, 2021
Receptor activator of nuclear factor-κB ligand (RANKL) has been found to induce osteoclastogenesis and bone resorption. However, the underlying molecular mechanisms remain unclear.

Hepatocyte growth factor overexpression promotes osteoclastogenesis and exacerbates bone loss in CIA mice

Journal of Orthopaedic Translation, 2021
Background: Hepatocyte growth factor (HGF) is a multifunctional growth factor that promotes various biological processes. However, the effect of HGF on bone metabolism in rheumatoid arthritis (RA) remains unknown. Here, we investigated the role of HGF in

Dencichine prevents ovariectomy-induced bone loss and inhibits osteoclastogenesis by inhibiting RANKL-associated NF-κB and MAPK signaling pathways

Journal of Pharmacological Sciences, 2021
Aims: To investigate the effect of dencichine on osteoclastogenesis in vivo and in vitro. Methods: RANKL-induced osteoclastogenesis were treated with different concentrations of dencichine.

Infection of RANKL-primed RAW-D macrophages with Porphyromonas gingivalis promotes osteoclastogenesis in a TNF-α-independent manner. [PDF]

PLoS ONE, 2012
Infection of macrophages with bacteria induces the production of pro-inflammatory cytokines including TNF-α. TNF-α directly stimulates osteoclast differentiation from bone marrow macrophages in vitro as well as indirectly via osteoblasts.

Insulin-like growth factor 2 promotes osteoclastogenesis increasing inflammatory cytokine levels under hypoxia

Journal of Pharmacological Sciences, 2022
Osteoporosis is caused by an imbalance in bone remodeling due to abnormal osteoclast (OC) formation and activation. Hypoxia at the site of inflammation promotes OC formation and activation in various species, including humans. We previously reported that

The crosstalk between MYC and mTORC1 during osteoclastogenesis

Frontiers in Cell and Developmental Biology, 2022
Osteoclasts are bone-resorbing cells that undergo extensive changes in morphology throughout their differentiation. Altered osteoclast differentiation and activity lead to changes in pathological bone resorption.
