(Universidad Autónoma de Guerrero (México), 2019-01)
H. pylori infection is the main risk factor for the gastric carcinogenesis. H. pylori can modify the expression levels of miRNAs and of proteins. GKN1 is a protein specific tissue that is decreased when there H. pylori ...
Regulación de la expresión del receptor NMDA por el extracto de ajo envejecido y S-alilcisteína en un modelo de isquemia cerebral
(Universidad Autónoma de Guerrero (México), 2011-01)
Introduction. Cerebral ischemia (CI) induces the formation of reactive oxygen species (ROS). ROS can induces the activation of transcription factors that regulate expression of genes among wich the glutamate receptor ...
