A synthetic DNA-binding inhibitor of SOX2 guides human induced pluripotent stem cells to differentiate into mesoderm.

abstract：:The -175 T greater than C mutation in the promoter of the A gamma- or G gamma-globin gene causes a 50-100 fold increase of the expression of the respective gene in adult erythroid cells (Hereditary Persistence of Fetal Hemoglobin). We show here that this mutation increases 3-9 fold the expression of a gamma-CAT report...
