{"doi":"10.3389/fphar.2023.1194875","title":"Editorial: Bone and Cartilage Diseases – The Role and Potential of Natural Products, Volume II","abstract":"As a bone and cartilage disease, osteoporosis, resulting from an imbalance in remodeling between bone formation and resorption, has become a major global public concern, often resulting in fracture and seriously impacting activities of daily living [Hernlund et al., 2013]. Evidence shows that osteoporosis increases the severity of cartilage damage via subchondral bone [Calvo et al., 2007;Wada et al., 2023]; thus, the treatment of osteoporosis also benefits cartilage health. Due to sex differences, females have a higher risk of developing osteoporosis than males [Patel et al., 2023]. Common anti-osteoporotic pharmaceuticals are effective in the prophylaxis and treatment of osteoporosis; however, various side effects resulting from western medicines drive many women to seek botanicals as an alternative therapy [Słupski et al., 2021]. Traditional Chinese medicine (TCM) is an excellent candidate for effective treatment with fewer side effects. In this work, five articles are included to discuss kidney-tonifying TCM (review), kidney-tonifying Chinese herbs (review), genistein (review), natural alkaloids (review), and dehydromiltirone (original study) for potential treatment of osteochondral diseases, particularly for osteoporosis.Based on the TCM theory that \"kidney governs bone,\" kidneys can be a target for the treatment of bone diseases using \"kidney-tonifying Chinese herbs\" and \"kidney-tonifying TCM (KTTCM).\" In a review paper by Duan and coworkers, they summarized KTTCM's ability to regulate estrogen expression, promote osteoblasts, inhibit osteoclasts, and restrain adipogenesis, as well as related molecular mechanisms including but not limited to osteoprotegerin (OPG)/receptor activator of nuclear factor kappa B (RANK)/RANK ligand (RANKL), bone morphogenetic protein (BMP)/suppressor of mothers against decapentaplegic (Smad), mitogen-activated protein kinases (MAPKs), and wingless/integrated (Wnt) signaling pathways. Furthermore, Jiao and colleagues reviewed the mechanisms by which kidney-tonifying Chinese herbs prevent osteoclastogenesis, emphasizing their immune effect.Genistein, a polyphenolic isoflavone, is found in varying dietary vegetables, such as soy beans and leguminous plants; it exhibits biological effects, such as anti-cancer, anti-inflammation, anti-oxidation, and bone/cartilage protection. The similarity in structure to estrogen provides genistein with estrogen-like activity in defending against osteoporosis and osteoarthritis. Wu and Liu summarized what is known about genistein in the treatment of bone and cartilage diseases, including intervertebral discs, osteoporosis, osteoarthritis, and rheumatoid arthritis. The involved molecular pathways were also discussed in each section to provide in-depth insights for future treatment. Ultimately, the authors also discussed clinical perspectives and limitations, such as low water solubility and the poor bioavailability of genistein, which need to be further investigated to improve genistein's curative effect.Natural alkaloids, a class of naturally occurring organic nitrogen-carrying bases, have diverse and crucial physiological effects on humans; this class includes strychnine, morphine, quinine, ephedrine, and nicotine. Additional evidence shows that alkaloids play a role in bone and cartilage diseases. Lin and colleagues reviewed the effect of natural alkaloids on mesenchymal stem cells, osteoblasts, osteoclasts, and related signaling pathways; their evidence supported the beneficial effects of alkaloids in promoting osteoblast proliferation and inhibiting osteoclast formation. Current efforts indicate that alkaloids could be a novel solution for the treatment of osteoporosis. Dehydromiltirone (DHT), a diterpenoid quinone originating in TCM, salvia miltiorrhiza Bge, and Salvia przewalskii Maxim, have been widely used to treat some diseases, such as liver diseases [Yue et al., 2014].
