Description

The study shows GLP-1R/ABCA1 mediates geniposide’s protective effects against cholesterol accumulation and differentiation inhibition, but the molecular mechanisms connecting cholesterol efflux to osteoblast function remain unexplained. Understanding this pathway could reveal new therapeutic targets for glucocorticoid-induced osteoporosis.
