Photoperiod-induced central actions of thyroid hormone are essential for medullary bone formation

Butterfield Natalie , Miszkiewicz Justyna , Logan John , Leitch Victoria , Yoshimura Takashi , Bassett Duncan , Williams Graham

Seasonal reproduction enables animals outside tropical regions to rear offspring in a favourable environment. Increasing day length triggers a hypothalamic relay involving thyrotropin, the type 2 deiodinase enzyme and thyroid hormone, which activates the hypothalamic-pituitary-gonadal axis to induce reproductive competence. Photoperiod regulates calcium metabolism and the egg-laying cycle in the Japanese quail (Coturnix japonica), and we hypothesised that activity of ...

An essential physiological role for MCT8 in bone

T3 is an important regulator of skeletal development and adult bone maintenance. Thyroid hormone action requires efficient transport of T4 and T3 into target cells. We hypothesized that monocarboxylate transporter-8, encoded by Mct8 on the X-chromosome, is an essential thyroid hormone transporter in bone. To test this hypothesis, we determined the juvenile and adult skeletal phenotypes of male Mct8 knockout mice (Mct8KO) and Mct8D1D2KO compo...
