Pancreas-Bone-Testis Axis

Abstract

Bone which has movement and support functions, is the largest organ of the body. Bone is regulated by hormonal signal but it also acts as an endocrine organ. Many peptide hormones such asosteocalcin are secreted from bone. Osteocalcin which is an osteoblast derived hormone, has two forms: “carboxylated (inactive) osteocalcin and decarboxylated (active) osteocalcin”. While inactive osteocalcin is found in bone matrix, active osteocalcin is given to blood circulation and acts as a multifunctional hormone. In the past ten years, numerous epidemiological, genetic and biochemical studies have revealed hormonal links between bone and pancreas, adipose tissue, gonads via active osteocalcin. In this review, a newly defined pathwaycalled pancreas-bone-testis axis which stimulates testosterone synthesis independent of hypothalamic hypophyseal testicular axis, is discussed.
