Abstract (original English)
Increased fructose consumption has been elucidated to contribute to metabolic diseases. Bone is a dynamic organ that undergoes constant remodeling. However, the effects of fructose on bone health are still in dispute. Here, we identified fructose deteriorated bone mineral density while promoting the abundance of bone marrow adipose tissue. Fructose remarkably promoted the bone marrow mesenchymal stem cells' (BMMSCs) adipogenic commitment at the expense of osteogenic commitment. Fructose boosted the glycolysis of BMMSCs and inhibited phosphorylation of adenosine 5'-monophosphate-activated protein kinase (AMPK), which played a crucial role in bone-fat alteration. Our results suggested that fructose potentiated bone loss and marrow adipose tissue accumulation by suppressing AMPK activation in BMMSCs. Understanding fructose which affected bone metabolism was thus of primary importance in order to establish preventative measures or treatments for this condition.
