Abstract
An imbalanced system of angiogenesis-osteoblasts-osteoclasts is regarded as the main factor in bone remodeling dysfunction diseases or osseointegration loss. Osteoclast precursors are the key cells that accelerate bone-specific angiogenesis and maintain normal osteoblast and osteoclast function. Graphene oxide is an effective scaffold surface modification agent with broad application prospects in bone tissue engineering. However, the effect of graphene oxide on the interaction between osteoclasts and angiogenesis has not yet been elucidated. In this study, a rat calvarial defect model was established and treated with an electrochemically derived nanographene oxide (ENGO) hydrogel. Higher angiogenesis and platelet-derived growth factor (PDGF) B in preosteoclasts were observed in the ENGO group compared with that in the control group. Moreover, in vitro experiments demonstrate the efficacy of ENGO in substantially reducing the expression of the receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclast-associated markers and inhibiting bone resorption activity. Additionally, ENGO enhances the secretion of the osteoclast-derived coupling factor PDGF-BB and promotes angiogenesis. Our investigation revealed the crucial role of isocitrate dehydrogenase 1 (IDH1) in the ENGO-mediated regulation of osteoclast differentiation and PDGF-BB secretion. The decreased expression of IDH1 reduces the level of histone lysine demethylase 7A (KDM7A) and subsequently increases the H3K9me2 level in the cathepsin K promoter region. In summary, we found that ENGO promotes angiogenesis by inhibiting the maturity of RANKL-induced osteoclasts and enhancing PDGF-BB secretion. These results indicate that ENGO holds promise for the application in fostering osteoclast-endothelial cell crosstalk, providing an effective strategy for treating bone resorption and osteoclast-related bone loss diseases.

Recent advances of NFATc1 in rheumatoid arthritis-related bone destruction: mechanisms and potential therapeutic targets. Mol Med 2024; 30:20.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease characterized by inflammation of the synovial tissue and joint bone destruction, often leading to significant disability. The main pathological manifestation of joint deformity in RA patients is bone destruction, which occurs due to the differentiation and proliferation of osteoclasts. The transcription factor nuclear factor-activated T cell 1 (NFATc1) plays a crucial role in this process. The regulation of NFATc1 in osteoclast differentiation is influenced by three main factors. Firstly, NFATc1 is activated through the upstream nuclear factor kappa-B ligand (RANKL)/RANK signaling pathway. Secondly, the Ca2+-related co-stimulatory signaling pathway amplifies NFATc1 activity. Finally, negative regulation of NFATc1 occurs through the action of cytokines such as B-cell Lymphoma 6 (Bcl-6), interferon regulatory factor 8 (IRF8), MAF basic leucine zipper transcription factor B (MafB), and LIM homeobox 2 (Lhx2). These three phases collectively govern NFATc1 transcription and subsequently affect the expression of downstream target genes including TRAF6 and NF-κB. Ultimately, this intricate regulatory network mediates osteoclast differentiation, fusion, and the degradation of both organic and inorganic components of the bone matrix. This review provides a comprehensive summary of recent advances in understanding the mechanism of NFATc1 in the context of RA-related bone destruction and discusses potential therapeutic agents that target NFATc1, with the aim of offering valuable insights for future research in the field of RA. To assess their potential as therapeutic agents for RA, we conducted a drug-like analysis of potential drugs with precise structures.
