Therefore, liraglutide can activate PI3K/AKT and cAMP/PKA signals by binding to GLP-1 receptors, acting on osteoblasts, ColonBroom capsules thereby promoting osteogenic differentiation and bone formation (Wu et al., 2017). Furthermore, the role of the GLP-1R/PI3K/AKT signaling pathway was also demonstrated in BMSC experiments. Another study showed that GLP-1RA of liraglutide and exenatide can increase bone mass, structural parameters and connectivity in ovariectomized mice (Pereira et al., 2015). Montes Castillo et al. The activation of Wnt/β-catenin pathway can promote the proliferation and differentiation of mesenchymal stem cells and osteoblasts, increase cell activity and promote osteogenic differentiation (Deng et al., 2019; Molagoda et al., 2019). Activation of GLP-1R by exendin-4 could promot the osteogenic differentiation and inhibite adipogenic differentiation through regulating PKA/β-catenin signaling pathway (Meng et al., 2016). Liraglutide could increase intracellular cAMP levels and β-catenin levels, while increasing the nuclear β-catenin content and transcriptional activity. Wnt/β-catenin pathway is a vital pathway regulating in regulating cell proliferation, apoptosis and tissue repair. The GLP-1R is a G protein-coupled receptor that is dependent on glucose and GLP-1 is a peptide hormone that acts directly on the beta cell to stimulate insulin secretion by activating signal transduction when glucose is present.

Similar to other GLP-1 receptor agonist agents, the most common adverse events reported were gastrointestinal-related and occurred more often at higher doses. Examples of GLP-1 agonists include semaglutide, liraglutide and tirzepatide. Liraglutide could significantly increase the OPG/RANKL ratio, indicating that liraglutide could inhibit the formation of osteoclasts. Previous research in our team found that GLP-1RA (geniposide) could significantly increase the mRNA and protein expression of OPN, Runx2, and ColonBroom capsules Osterix in DEX-treated MC3T3-E1 cells by activating the ERK MAPK signaling pathway. This concern stems from rodent studies showing an increase in medullary thyroid cancer (MTC), which led to a Food and Drug Administration (FDA) warning against their use in patients with a personal or family history of MTC or multiple endocrine neoplasia, type 2 (MEN2). Appetite is a complex process that results from the integration of multiple signals at the hypothalamus. Because GLP-1 affects multiple systems, careful monitoring by a healthcare provider is essential. Muscle, especially axial muscle, is essential for posture, physical function and overall well-being. The combination of effective weight management strategies and hormone regulation could very well enhance your overall well-being. It has developed and commercialized novel biologics, biosimilars, and complex small molecule APIs in India and several key global markets, as well as generic formulations in the U.S.



Key data enabling the development of two GLP1RA for obesity therapy (liraglutide 3 mg daily and semaglutide 2.4 mg once weekly) are discussed. At present, there are evidences that GLP-1RAs and their analogs can enhance bone density and improve bone quality. There are almost 3,000 cases in federal multidistrict litigation (MDL) known as "GLP-1 Receptor Agonists Products Liability Litigation." It is being heard in the Eastern District of Pennsylvania. The tests above are most often prescribed (and covered by insurance) for people who already exhibit some symptoms of heart trouble. Good Laboratory Practice (GLP) is a quality system concerned with the organizational process and the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived and reported. The OPG/RANKL signaling system is critical in the pathogenesis of bone related diseases caused by increased bone resorption (Hofbauer and Schoppet, 2004; Yang et al., 2020). Nuche-Berenguer et al.



GLP-1RA of Exendin-4 mainly inhibited bone resorption by regulating OPG/RANKL ratio, and increases the expression of osteogenic related genes OC, COL1, Runx2, and ALP to promote bone formation (Ma et al., 2013). In addition, this study detected OPG and RANKL mRNA expression and serum concentration. The result observed that the ratio of OPG/RANKL in T2DM was 0.81 and that this value rose to a height of 1.25 after GLP-1 treatment. This strategy of using a bivalent GLP-1/Fc fusion protein as a therapeutic agent is a novel approach for the treatment of diabetes. Mitogen-activated protein kinase (MAPK) belongs to silk/threonine protein kinase, mainly including extracellular signal-regulated kinase (Erk1/2), Jun N-terminal kinase (JNK) subfamily, p38 mitogen-activated protein kinase and ERK5 (Wang, 2007; Wagner and Nebreda, 2009; Arthur and Ley, 2013). The extracellular ligand play a role in regulating bone formation and skeletal metabolism, at least in part, through signal MAPK pathways (Greenblatt et al., 2010). Studies have shown that GLP-1RA regulate MAPK signaling pathway through GLP-1R to play the anti-diabetes, anti-tumor and anti-atherosclerosis effects (Nomiyama et al., 2014; Tang et al., 2019; Yue et al., 2019). Studies have found that GLP-1RA have similar effects in alleviating osteoporosis and preventing fractures (Nuche-Berenguer et al., 2010; Feng et al., 2016). Feng et al.
