Description

The study demonstrates that dexamethasone-induced cholesterol accumulation reduces osteoblast activity, but the cellular mechanisms by which excess cholesterol disrupts bone cell function are not elucidated. This knowledge gap limits understanding of lipid-bone interactions in metabolic bone diseases.
