Golpe de calor a la epigenética de la obesidad.

from Cienciaes.com

Un grupo de investigadores del Instituto de Alimentos, Nutrición y Salud de Zúrich, Suiza, ha sometido a ratones a temperaturas frías o cálidas antes de la concepción. Lo que han encontrado es que los padres, pero no de las madres, sometidos a bajas temperaturas antes de la concepción de sus hijos, generan una descendencia con un metabolismo mucho más resistente al desarrollo de la obesidad en la edad adulta. Los estudios revelan también que estos cambios se deben a modificaciones químicas, es decir, epigenéticas en ciertos grupos de genes, de los que ya era conocido influyen sobre el desarrollo del tejido adiposo marrón. Parece lógico pensar, aunque no está demostrado, que la localización más externa de los testículos, pero no de los ovarios, puede ser un factor que explique la diferencia entre padres y madres.
