Thyroid hormone analog 3,5-diiodothyropropionic acid promotes healthy vasculature in the adult myocardium independent of thyroid effects on cardiac function

Yingheng Liu, Dajun Wang, Rebecca A. Redetzke, Benjamin A. Sherer, and A. Martin Gerdes Abstract:  Liu Y, Wang D, Redetzke RA, Sherer BA, Gerdes AM. Thyroid hormone analog 3,5-diiodothyropropionic acid promotes healthy vasculature in the adult myocardium independent of thyroid effects on cardiac function. Am J Physiol Heart Circ Physiol 296: H1551–H1557, 2009. First published […]

The tricyclic antidepressant desipramine inhibits T3 import into primary neurons

Stephan Roth, Anita Kinne, Ulrich Schweizer Abstract:  Transport of thyroid hormones across the plasma membrane is required for binding to their nuclear receptors. Monocarboxylate transporter 8 (MCT8) is a plasma membrane thyroid hormone transport protein, which has recently gained much attention, since mutations in MCT8 are associated with severe mental retardation in patients afflicted with […]

Characterization of thyroid hormone transporter expression during tissue-specific metamorphic events in Xenopus tropicalis

Kristin A. Connors, Joe J. Korte, Grant W. Anderson, Sigmund J. Degitz Abstract:  Thyroid hormone (TH) induces the dramatic morphological and physiological changes that together comprise amphibian metamorphosis. TH-responsive tissues vary widely with developmental timing of TH-induced changes. How larval tadpole tissues are able to employ distinct metamorphic programs in a developmental stage- and TH-dependent […]

Thyroid hormone action during brain development: More questions than answers

Sigrun Horn, Heike Heuer Abstract:  Thyroid hormone is essential for proper brain development since it acts on processes such as neuronal migration and differentiation, myelination and synaptogenesis. In this review, we summarize the consequences of thyroid hormone deficiency for brain development with special focus on the cerebellum, an important target of thyroid action. In addition, […]

Essential molecular determinants for thyroid hormone transport and first structural implications for monocarboxylate transporter 8

Anita Kinne, Gunnar Kleinau, Carolin S. Hoefig, Annette Grüters, Josef Köhrle, Gerd Krause, Ulrich Schweizer Abstract:  Monocarboxylate transporter 8 (MCT8, SLC16A2) is a thyroid hormone (TH) transmembrane transport protein mutated in Allan-Herndon-Dudley syndrome, a severe Xlinked psychomotor retardation. The neurological and endocrine phenotypes of patients deficient in MCT8 function underscore the physiological significance of carriermediated […]

Retinoic Acid Induces Expression of the Thyroid Hormone Transporter, Monocarboxylate Transporter 8 (Mct8)

Takahiko Kogai, Yan-Yun Liu, Laura L. Richter, Kaizeen Mody, Hiroyuki Kagechika, and Gregory A. Brent Abstract:  Retinoic acid (RA) and thyroid hormone are critical for differentiation and organogenesis in the embryo. Mct8 (monocarboxylate transporter 8), expressed predominantly in the brain and placenta, mediates thyroid hormone uptake from the circulation and is required for normal neural […]

Lack of Action of Exogenously Administered T3 on the Fetal Rat Brain Despite Expression of the Monocarboxylate Transporter 8

Carmen Grijota-Martínez, Diego Díez, Gabriella Morreale de Escobar, Juan Bernal, and Beatriz Morte Abstract:  Mutations of the monocarboxylate transporter 8 gene (MCT8, SLC16A2) cause the Allan-Herndon- Dudley syndrome, an X-linked syndrome of severe intellectual deficit and neurological impairment. Mct8 transports thyroid hormones (T4 and T3), and the Allan-Herndon-Dudley syndrome is likely caused by lack of […]

Zebrafish as a model for monocarboxyl transporter 8-deficiency

Gad David Vatine, David Zada, Tali Lerer-Goldshtein, Adi Tovin, Guy Malkinson, Karina Yaniv and Lior Appelbaum Abstract:  Allan Herndon Dudley syndrome (AHDS) is a severe psychomotor retardation characterized by neurological impairment and abnormal thyroid hormone (TH) levels. Mutations in the TH transporter, monocarboxylate transporter 8 (MCT8), are associated with AHDS. MCT8-knockout mice exhibit impaired TH […]
