Role of non-classical actions of androgens in musculoskeletal physiology

点击翻译按钮获取中文摘要

Androgens (male sex hormones) are important for growth-maintenance of muscle and bone. The classical action of androgens is to bind the androgen receptor (AR) and regulate target genes. They can also act via non-classical AR mechanisms through other cellular pathways. To understand the role of non-classical actions in the musculoskeletal system we will study mice in which androgens can only act via this pathway. This knowledge is important for the treatment of osteoporosis and muscle wasting.
