Resumen
El movimiento como agente epigenético. En morfología comparada implicamos movimiento cuando el animal o cualquiera de sus partes se mueve para realizar funciones vitales. En los tetrápodos, este movimiento se realiza a través de las extremidades. En nuestro laboratorio trabajamos la diversidad, desarrollo e influencia de los factores epigenéticos, del aparato locomotor de los tetrápodos, particularmente de los anfibios. Identificamos como factores epigenéticos aquellos que modifican la expresión de genes de un organismo sin alterar su secuencia de agentes. En este contexto, surgen algunas preguntas: ¿puede un tetrápodo moverse en exceso para generar patologías en sus tejidos constituyentes? ¿Este movimiento excesivo tendrá las mismas consecuencias para el desarrollo o la edad adulta? Por el contrario, ¿Cuáles son las consecuencias de la inmovilidad para el rendimiento locomotor? Nuestro grupo aborda estos temas complementando herramientas de anatomía tradicional, histología, experimentación, para analizar la diversidad y desarrollo del sistema tendo-musculoesquelético del aparato locomotor de Anura, haciendo énfasis en elementos poco estudiados, como tendones y sesamoideos. Esto nos ha permitido contrastar como el fenotipo "normal" se ve modificado por la falta o exceso de movimiento, mostrando que este último es un factor epigenético importante para la correcta formación, diferenciación y función de los órganos y tejidos del sistema musculoesquelético.
The movement as epgenetic agent. In comparative morphology we imply movement when the animal or any of their parts moves to perform vital functions. In tetrapods, this movement is made through limbs. In our laboratory, we work on diversity, development and influence of epigenetic factors, of the locomotor system of tetrapod, particularly amphibians. We identify as epigenetic factors those that modify the expression of genes of an organism without altering its sequence agents. In this context, some questions are arising: can a tetrapod move excessively to generate pathologies in their constituent tissues? Is this excessive movement will have the same consequences for the development or adulthood? By contrast, what are the consequences of the immobility for locomotor performance? Our group addresses these issues complementing tools from anatomy traditional, histology, experimentation, to analyze the diversity and development of tendo-musculoskeletal system of the locomotor aparatus of Anura, emphasizing inscarcely studied elements, such as tendons and sesamoid. This has allowed us to contrast as the "normal" phenotype is modified by the lack or excess movement, showing that the latter is a major epigenetic factor for the correct formation, differentiation and function of organs and tissues of the musculoskeletal system.
