Acceleration of tooth movement during orthodontic treatment is challenging, with osteoclast-mediated bone resorption on the compressive side being the rate-limiting step. Recent studies have demonstrated that mechanoreceptors on the surface of monocytes/macrophages, especially adhesion G protein-coupled receptors (aGPCRs), play important roles in force ***, its role in the regulation of osteoclast differentiation remains unclear. Herein, through single-cell analysis, we revealed that CD97, a novel mechanosensitive aGPCR, was expressed in macrophages. Compression upregulated CD97 expression and inhibited osteoclast differentiation;while knockdown of CD97 partially rescued osteoclast differentiation. It suggests that CD97 may be an important mechanosensitive receptor during osteoclast differentiation. RNA sequencing analysis showed that the Rap1a/ERK signalling pathway mediates the effects of CD97 on osteoclast differentiation under compression. Consistently, we clarified that administration of the Rap1a inhibitor GGTI298 increased osteoclast activity, thereby accelerating tooth movement. In conclusion,our results indicate that CD97 suppresses osteoclast differentiation through the Rap1a/ERK signalling pathway under orthodontic compressive force.

Alcoholic liver disease (ALD) is one of the major global public health problems. Yeast extract (YE)， a product prepared from yeast， has been proven to have antioxidant and anti-inflammatory properties. However， the potential role of YE in the prevention of ALD remains unclear. The present study aimed to investigate the protective effects of YE on ALD and explore the underlying mechanism based on gut microbiota. The result showed that YE supplementation significantly ameliorated chronic alcohol exposure-induced liver injury in mice. In addition， YE counteracted alcohol-induced gut dysbiosis， intestinal barrier dysfunction， lipopolysaccharide (LPS) leakage-induced inflammatory response in the liver. Moreover， microbiota depletion by a broad-spectrum antibiotic was sufficient to block the protective effect of YE on ALD， indicating the contribution of gut dysbiosis modulation to the hepatoprotective role of YE. Furthermore， we demonstrated the causal relationship between gut microbiota and hepatoprotective effects of YE with the fecal microbiota transplantation (FMT) experiment. Compared with the ALD-FMT mice， gut dysbiosis， intestinal barrier dysfunction， LPS/TLR4 signaling pathway activation， and liver inflammatory response were significantly improved in the YE-FMT mice. Together， our findings highlight that dietary YE protects against ALD through gut dysbiosis correction.

DNA methyltransferase(MTase) activity detection has received increasing attention as a promising biomarker and therapeutic target. However, most of these detection methods rely on endonuclease digestion and signal groups ***, we present a novel platform for sensing DNA MTase activity that overcomes these limitations. Our approach is both endonuclease-free and label-free, utilizing a combination of a high-affinity streptavidin-methyl-CpG-binding domain(SA-MBD) protein and surface plasmon resonance(SPR) technology. The SA-MBD protein specifically recognizes a hairpin probe containing methylated CpG sites, which is treated with *** MTase. This recognition event generates a corresponding SPR response signal. The limit of detection is as low as 0.016 U/mL, owing to the high-a ffinity of the SA-MBD ***, we have demonstrated the feasibility of our method for *** MTase activity analysis in serum and inhibitor screening, which implies the potential prospects for biomedical research.
