Bone Abstracts

Introduction: For the very first time were assessed in vivo the metabolic and lipid profiles of osteocytes. During menopause period the appearance of an osteoporotic condition can be associated with an overall metabolic decline in bone cells, as well an increase of reactive oxygen species (ROS), and we hypothesized that it is mainly attributed to osteocytes metabolic and lipid changes, which could be apparently attenuated after raising blood estradiol (E2) levels. To ...

Introduction: Osteocytes play a major role in the bone remodelling unit (BRU). Thus, we hypothesize that mitochondrial bioenergetics impairment and mitochondrial/peroxisomal fatty acid β-oxidation unbalance is a cause of osteocytes metabolic decline during 17β-estradiol (E2) reduction. E2 and a phytochemical substitute, coumestrol (COU) were used (30 mg/kg during 24 h in ovariectomized rats in order to compare bone loss with sham-operated animal...
