Adiponectin (AdipoQ), a hormone abundantly secreted by adipose tissues, has multiple beneficial functions, including insulin sensitization as well as lipid and glucose metabolism. It has been reported that bone controls energy metabolism through an endocrine-based mechanism. In this study, we observed that bone also acts as an important endocrine source for AdipoQ, and its capacity in osteoblasts is controlled by the forkhead box P1 (FOXP1) transcriptional factor. Deletion of the Foxp1 gene in osteoblasts led to augmentation of AdipoQ levels accompanied by fueled energy expenditure in adipose tissues. In contrast, overexpression of Foxp1 in bones impaired AdipoQ secretion and restrained energy consumption. Chromatin immunoprecipitation sequencing (ChIP-seq) analysis revealed that AdipoQ expression, which increases as a function of bone age, is directly controlled by FOXP1. Our results indicate that bones, especially aged bones, provide an important source of a set of endocrine factors, including AdipoQ, that control body metabolism. © 2021 American Society for Bone and Mineral Research (ASBMR).
