Kemik Yetmezliğinde Hidrojen Sülfürün Terapötik Potansiyeli

Özet (abstract)

H2S, recognized as the third gaseous signaling molecule following NO and CO, holds significant potential for therapeutic applications in diseases characterized by bone deficiency. Considerable advancements have been achieved in the development of bone scaffold materials incorporating H2S donors, as well as in the creation of innovative H2S-releasing pharmacological agents. Exogenous supplementation of H2S has exhibited pronounced bone-protective effects in animal models of osteoporosis, fractures, and periodontitis. These therapeutic effects are mediated through various mechanisms, including anti-inflammatory and antioxidant activities, alongside the bidirectional regulation of bone metabolic balance. Mechanistically, H2S plays a critical role throughout the entire bone remodeling process—encompassing the resorption, reversal, and formation phases—by modulating osteoclast generation and activation, osteoblast differentiation and maturation, and maintaining mesenchymal stem cell function. This modulation occurs via key signaling pathways, such as the RANKL/OPG, the Wnt/β-catenin, and the p38-MAPK signaling pathway. A deeper understanding of the role of H2S in bone deficiency can lead to the discovery of new therapeutic targets, while innovative H2S donors offer highly promising new treatments for patients with bone deficiency.
