Mechanisms controlling cell specification and differentiation in hematopoiesis. Molecular control of erythropoiesis: -mechanisms of Hereditary Persistence of Fetal Hemoglobin: research on globin gene activity and function (mRNA translation, inherited structural and regulatory defects, transcriptional control). -transcriptional control of the expression of genes encoding erythroid transcription factors, in particular GATA 1 (and its transcriptional and post-transcriptional regulation) and Sox6. -study of the transcriptional regulation of the “stem cell” gene c-Kit -identification and functional analysis of genes differentially expressed during erythropoiesis -signal transduction mechanisms controlling cell commitment and differentiation in normal and pathological (leukemias, myelodysplastic syndromes) erythropoiesis In vitro biochemical assays, cell culture, transfections, and mouse models are employed in these studies.
