Understanding of the mechanisms involved in gamma- to beta-globin switching may be important for development of treatment options for b-thalassemia. Such studies require the availability of relevant cellular model systems. One such cell type is Hu11, a mouse erythroleukemia [MEL] cell line containing the human b-locus. MEL and Hu11 cells differentiate in the presence of the chemical dimethyl sulfoxide [DMSO]. Nevertheless, levels of gamma-globin induction in Hu11 cells after DMSO treatment have not been determined. In the present study, we determined gamma-globin levels in Hu11 cells after treatment with various DMSO concentrations. Materials andmethods:
Hu11 cells were cultivated in various DMSO concentrations and the levels of gamma-globin were determined by real-time PCR.Results:
Our study showed that hemoglobin in Hu11 cells treated with 1% and 2% DMSO was increased by approximately 5 and 10 folds. Moreover real-time PCR results showed that g-globin levels using the indicated DMSO levels were increased by 66 and 298 folds, respectively. Hu11 cells differentiate in the presence of DMSO, and in doing so, their gamma-globin levels are increased. Therefore these cells can be used to study the mechanisms of gamma-globin induction. Such studies may be beneficial for the treatment of beta-thalassemia
