Alzheimer, cáncer, glucosa y serina.

from Cienciaes.com

Una difícil lección que los científicos dedicados al estudio de la biología de las moléculas deben aprender es que una misma molécula puede ejercer múltiples funciones, en diferentes tipos de células. Una de estas moléculas es el enzima llamado fosfoglicerato deshidrogenasa. El enzima fosfoglicerato deshidrogenasa es un enzima importante en el metabolismo de la glucosa y también en el del aminoácido serina, uno de los veinte aminoácidos necesarios para la fabricación de todas las proteínas de nuestro organismo. La cantidad de fosfoglicerato deshidrogenasa producida se ha visto asociada con la resistencia de las células tumorales de carcinoma hepático a un fármaco antitumoral. Por otro lado, en 2020, un equipo de investigadores franceses estableció una relación entre la progresión de la enfermedad de Alzheimer y el estado del metabolismo de la serina. Ahora, un nuevo estudio parece indicar lo contrario, por lo que se abre una controversia científica acerca de la conveniencia o no de consumir suplementos de serina como medio para frenar la enfermedad de Alzheimer.
