The general aim of this proposal is to analyse the gene expression of erythroid progenitor cells from beta−thalassemia patients, for the identification of approaches enhabling the induction of fetal hemoglobin (HbF) and production of adult hemoglobin (HbA), of possible interest for the therapy of beta−thalassemia. The objective of Task 1 is the recruitment and genetic characterization of the beta−thalassemia patients involved in this study. The objective of Task 2 is the characterization of the molecular mechanisms of action of novel HbF inducers and their use in combination with gene therapy employing lentiviral vectors. The objective of Task 3 is the study of gene expression in HPFH patients and in beta−thalassemia patients producing very high levels of HbF. The objective of Task 4 is the analysis of micro RNA network in HPFH cells and in erythroid progenitors induced to HbF production. The objective of Task 5 is the application of the read−through approach on HbA production by beta°39 thalassemic cells and transgenic animals. The objective of Task 6 is the study of the effects of siRNAs or antisense DNA or DNA−PNA chimeras on target mRNA sequences. Task 7 is dedicated to exploitation, for the identification of Biotech companies interested in the developed protocols and patents.

Abstract

The general aim of this proposal is to analyse the gene expression of erythroid progenitor cells from beta−thalassemia patients, for the identification of approaches enhabling the induction of fetal hemoglobin (HbF) and production of adult hemoglobin (HbA), of possible interest for the therapy of beta−thalassemia. The objective of Task 1 is the recruitment and genetic characterization of the beta−thalassemia patients involved in this study. The objective of Task 2 is the characterization of the molecular mechanisms of action of novel HbF inducers and their use in combination with gene therapy employing lentiviral vectors. The objective of Task 3 is the study of gene expression in HPFH patients and in beta−thalassemia patients producing very high levels of HbF. The objective of Task 4 is the analysis of micro RNA network in HPFH cells and in erythroid progenitors induced to HbF production. The objective of Task 5 is the application of the read−through approach on HbA production by beta°39 thalassemic cells and transgenic animals. The objective of Task 6 is the study of the effects of siRNAs or antisense DNA or DNA−PNA chimeras on target mRNA sequences. Task 7 is dedicated to exploitation, for the identification of Biotech companies interested in the developed protocols and patents.
