Selenium supplementation fails to improve thyroid hormone metabolism in subjects with SBP2 gene mutations

Selenium (Se) is an essential trace element needed for the biosynthesis of selenoproteins. Biosynthesis of such proteins depends on the selenocysteine incorporation sequence binding protein 2 (SBP2), which represents a key trans-acting factor during the translation process. We recently described children with mutations in SBP2 gene who displayed an abnormal thyroid function test(s) and reduced selenoprotein concentrations. Now we aimed to improve selenoprotein biosynthesis and...

During the last decade induced overexpression of defined transcription factors has been shown to have a driving effect on the differentiation of embryonic stem cells (ESCs) into many specific cell types. Nevertheless, the generation of protocols promoting a coordinate self-assembly of differentiated cells into distinct morphological units with also functional properties reminiscent of organs and tissues in vivo are still very sparse. Recently, we have reported the gen...

Background: Oral glucose tolerance test (OGTT) is a step in the evaluation of children and adolescents with tall stature for documenting a possible autonomous GH secretion.Aim: Assessment of GH dynamics in OGTT in children and adolescents with tall stature in various stages of pubertal development for documenting a possible autonomous GH secretion.Method: Our study included 44 subjects, 18 girls and 26 boys, with age between 6.5 an...

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...
