骨是由细胞、细胞外基质和矿化部分组成的动态组织。成骨细胞负责适当的骨形成和重塑以及功能。这些过程是吸能的,需要三磷酸腺苷 (ATP) 形式的细胞能量,三磷酸腺苷来自多种来源,如葡萄糖、脂肪酸和氨基酸。然而,其他脂质(例如胆固醇)也被发现在骨稳态中发挥着关键作用,并且也有助于成骨细胞的整体生物能能力。此外,一些流行病学研究发现,癌症患者胆固醇升高、心血管疾病、骨质疏松风险增加和骨转移增加之间存在联系。本综述重点关注胆固醇、其衍生物和降胆固醇药物(他汀类药物)如何调节成骨细胞功能和骨形成。它还强调了胆固醇与成骨细胞相互作用的分子机制。
Bone is a dynamic tissue composed of cells, an extracellular matrix, and mineralized portion. Osteoblasts are responsible for proper bone formation and remodeling, and function. These processes are endergonic and require cellular energy in the form of adenosine triphosphate (ATP), which is derived from various sources such as glucose, fatty acids, and amino acids. However, other lipids such as cholesterol have also been found to play a critical role in bone homeostasis and can also contribute to the overall bioenergetic capacity of osteoblasts. In addition, several epidemiological studies have found a link between elevated cholesterol, cardiovascular disease, an enhanced risk of osteoporosis, and increased bone metastasis in cancer patients. This review focuses on how cholesterol, its derivatives, and cholesterol-lowering medications (statins) regulate osteoblast function and bone formation. It also highlights the molecular mechanisms underlying the cholesterol–osteoblast crosstalk.
