Impaired bone homeostasis in amyotrophic lateral sclerosis mice with muscle atrophy

Abstract

Background: The effects of ALS on bone homeostasis are poorly understood. Results: ALS mice with muscle atrophy have reduced bone mass associated with multiple impairments of osteoblast properties and striking acceleration of osteoclast formation in bone. Conclusion: Abnormal bone remodeling results in dramatic bone loss during the progression of muscle atrophy in ALS mice. Significance: This study may help to define therapeutic targets for ALS patients.
