The development of cellular systems for the screening of molecules able to induce the production of fetal or adult hemoglobin in erythroid cells isolated from b-thalassemia patients is very important for the identification of molecules of interest for pharmacological therapy of thalassemia. This article reports the development of a cellular system for the identification of inducers of fetal hemoglobin preferentially acting on the human g-globin gene promoter. To achieve this aim, green and red fluorescence protein genes were cloned under the control of g-globin and b-globin promoters, respectively. The developed K562 clones were tested for the increase of fluorescence after treatment with sodium butyrate and hydroxyurea, two well-known inducers of fetal hemoglobin.
