骨质疏松症是一种常见的骨骼疾病,其特征是骨量减少以及骨微结构退化,从而导致骨脆性增加和骨折风险升高。近几十年来,关于病因机制的研究强调,炎症、氧化应激以及骨细胞衰老都对骨质疏松症的发展有促进作用。研究表明,血红素加氧酶1(HO - 1)是一种催化血红素降解的诱导酶,具有抗炎、抗氧化应激和抗凋亡的特性。新出现的证据显示,HO - 1在维持骨稳态中至关重要,这使HO - 1成为骨质疏松症治疗的一个潜在靶点。在这篇综述中,我们旨在介绍目前关于HO - 1生物学及其调控的知识,特别关注其在骨稳态和骨质疏松症中的作用。我们还探讨了基于HO - 1的药物疗法在骨质疏松症治疗中的潜力以及临床转化过程中面临的问题。
Osteoporosis is a prevalent bone disorder characterized by bone mass reduction and deterioration of bone microarchitecture leading to bone fragility and fracture risk. In recent decades, knowledge regarding the etiological mechanisms emphasizes that inflammation, oxidative stress and senescence of bone cells contribute to the development of osteoporosis. Studies have demonstrated that heme oxygenase 1 (HO-1), an inducible enzyme catalyzing heme degradation, exhibits anti-inflammatory, anti-oxidative stress and anti-apoptosis properties. Emerging evidence has revealed that HO-1 is critical in the maintenance of bone homeostasis, making HO-1 a potential target for osteoporosis treatment. In this Review, we aim to provide an introduction to current knowledge of HO-1 biology and its regulation, focusing specifically on its roles in bone homeostasis and osteoporosis. We also examine the potential of HO-1-based pharmacological therapeutics for osteoporosis and issues faced during clinical translation.
