Abstract:

Osteoporosis is a chronic disease whose symptoms include a reduction in bone strength, osteopenia, and damage to the bone microstructure. Ferulic acids are natural polyphenols present in various fruits that suppress the fusion and apoptosis of mature osteoclasts. Rats were divided into sham, control (osteoporosis), 10 mg/kg body weight ferulic acid, 20 mg/kg body weight ferulic acid, and 30 mg/kg body weight ferulic acid treatment groups. Osteoporosis was induced in neonatal by administration of dexamethasone (glucocorticoids). Bone mineral density (BMD), osteocalcin and alkaline phosphatase (ALP) levels,bone mechanical parameters, and mRNA and protein levels of sirtuin1 (SIRT1) and nuclear factor kappa-B (NF-κB) in the osteoporotic neonatal rats were assessed. Histopathological analysis was also conducted. Treatment with 20 and 30 mg/kg body weight ferulic acid increased BMD by 25% and 141.7%, respectively, but reduced ALP and osteocalcin levels. Furthermore, treatment with 20 or 30 mg/kg body weight ferulic acid significantly reduced the pixel intensity and significantly increased the peak load and ultimate stiffness. Ferulic acid significantly increased the mRNA and protein levels of SIRT1 and reduced those of NF-κB. Finally, the histopathological analysis showed that ferulic acid increased BMD. In summary, ferulic acid exhibited protective effects against osteoporosis in neonatal rats.
