Abstract (original English)
Selective serotonin reuptake inhibitors are the most commonly prescribed antidepressants worldwide, which have been reported to exert potential detrimental effects on bone mineral density and increase the risk of developing fractures. The present study aimed to investigate the pathways underlying the negative effects of fluoxetine on bone using mesenchymal stem cells (MSCs) derived from rat adipose tissue as a source of osteoprogenitor cells. MSCs were harvested from adipose tissue using a collagenase enzyme digestion method and were allowed to differentiate into osteoprogenitor cells. Various concentrations of fluoxetine were added to the cells, which were harvested and analyzed by flow cytometry to detect apoptotic markers Annexin V and caspase‑3, in order to assess the levels of apoptosis. The levels of endogenous serotonin released in the extracellular matrix were measured using a serotonin ELISA kit. The underlying molecular pathways associated with the effects of fluoxetine on bone were investigated with reverse transcription‑quantitative polymerase chain reaction. The results of the present study revealed a significant dose‑dependent increase in apoptosis in response to increasing doses of fluoxetine, which was independent of serotonin levels in the culture supernatant. These findings indicated that fluoxetine exerted a direct inhibitory effect on bone cells via an apopt
