A new route to thyrotoxicosis?Thyroidal extracellular glutathione peroxidase: a potential regulator of thyroid-hormone synthesis AF Howie, SW Walker, B Akesson, JR Arthur, GJ Beckett. Biochemical Journal 1995; 308: 713-717Department of Histopathology, University of Cambridge, UK Human thyrocytes were found to synthesise and secrete the selenoenzyme extracellular glutathione peroxidase (E-GPX), a process which was controlled by the Ca2+/phosphoinositol second messenger cas cade. The potential involvement of thyroidal E-GPX in the regulation of thyroid hormone synthesis and in the protection of the thyrocyte from peroxidative damage is discussed.
