          Abstract

          El presente artículo de revisión tuvo como objetivo actualizar conceptos sobre el metabolismo de las hormonas tiroideas y su relación con la reproducción en el cerdo. Fue analizada la literatura disponible de los últimos 25 años en las bases de datos BBCS-LILACS, Fuente Académica, IB-PsycINFO, IB-SSCI, IB-Scielo, Scopus y Scirus, al igual que artículos históricos, textos y referencias citadas en trabajos públicos. Se adquirió información pertinente relacionada con los objetivos propuestos, destacando las múltiples funcionalidades y la relación que tienen las hormonas tiroideas con los diferentes tejidos del organismo, clasificándose en cuatro secciones a saber: síntesis, transporte y metabolismo; receptores y mecanismos de acción; efectos de las hormonas tiroideas; hormonas tiroideas y reproducción. Puede concluirse que las hormonas tiroideas tienen acciones importantes en el ovario y el testículo, y juegan un papel crucial en el desarrollo de las células responsables de la reproducción. Alteraciones en estas hormonas pueden desencadenar infertilidad, pues un nivel adecuado de las mismas es necesario para la ovulación y la espermatogénesis.

          Translated abstract

          This review article aimed to update concepts on the metabolism of thyroid hormones and their relationship with boar reproduction. The available literature of the past 25 years in the BBCS- LILACS, Academic source, IB-PsycINFO, SSCI IB-, IB-SciELO, Scopus and Scirus databases as well as historical articles, texts and references cited work public, were analyzed. Relevant information to the objectives was gotten, highlighting the multiple functionality and the relationship thyroid hormones have with the different tissues in the organism, thus being classified in four sections as follows: synthesis, transport and metabolism; receptors and mechanisms of action; effects of thyroid hormones; thyroid hormones and reproduction. It can be concluded that thyroid hormones have important roles in ovaries and testicles, and play a crucial role in the development of reproduction cells. Changes in these hormones can produce infertility, as an adequate level of these hormones is necessary for ovulation and spermatogenesis.

          Physiological and molecular basis of thyroid hormone action.

          P M Yen (2001)
          Thyroid hormones (THs) play critical roles in the differentiation, growth, metabolism, and physiological function of virtually all tissues. TH binds to receptors that are ligand-regulatable transcription factors belonging to the nuclear hormone receptor superfamily. Tremendous progress has been made recently in our understanding of the molecular mechanisms that underlie TH action. In this review, we present the major advances in our knowledge of the molecular mechanisms of TH action and their implications for TH action in specific tissues, resistance to thyroid hormone syndrome, and genetically engineered mouse models.

            Mechanisms of thyroid hormone action.

            Our understanding of thyroid hormone action has been substantially altered by recent clinical observations of thyroid signaling defects in syndromes of hormone resistance and in a broad range of conditions, including profound mental retardation, obesity, metabolic disorders, and a number of cancers. The mechanism of thyroid hormone action has been informed by these clinical observations as well as by animal models and has influenced the way we view the role of local ligand availability; tissue and cell-specific thyroid hormone transporters, corepressors, and coactivators; thyroid hormone receptor (TR) isoform-specific action; and cross-talk in metabolic regulation and neural development. In some cases, our new understanding has already been translated into therapeutic strategies, especially for treating hyperlipidemia and obesity, and other drugs are in development to treat cardiac disease and cancer and to improve cognitive function.
