WebThe regulation of HIF-1 is a complex process and involves a number of molecules and pathways. Among these mechanisms a direct regulatory role of reactive oxygen species (ROS) on HIF-1 alpha subunit has received a great deal of attention and the existing body of literature includes many contradictory findings. Web26 de nov. de 2012 · HIF1 regulates the expression of Glut1 by direct binding to the Glut1 promoter. Similarly, HIF1-regulated glycolytic enzymes are direct HIF1 target genes. This raises the question of whether or not HIF1 regulation of perforin gene expression is direct or indirect.
