Gene transfer improves erythroid development in ribosomal protein S19-deficient Diamond-Blackfan anemia.
(2002) In Blood 100(8). p.2724-2731- Abstract
- Diamond-Blackfan anemia (DBA) is a congenital bone marrow failure syndrome characterized by a specific deficiency in erythroid progenitors. Forty percent of the patients are blood transfusion-dependent. Recent reports show that the ribosomal protein S19 (RPS19) gene is mutated in 25% of all patients with DBA. We constructed oncoretroviral vectors containing the RPS19 gene to develop gene therapy for RPS19-deficient DBA. These vectors were used to introduce the RPS19 gene into CD34(+) bone marrow (BM) cells from 4 patients with DBA with RPS19 gene mutations. Overexpression of the RPS19 transgene increased the number of erythroid colonies by almost 3-fold. High expression levels of the RPS19 transgene improved erythroid colony-forming... (More)

Overexpression of the RPS19 transgene increased the number of erythroid colonies by almost 3-fold. High expression levels of the RPS19 transgene improved erythroid colony-forming ability substantially whereas low expression levels had no effect. Overexpression of RPS19 had no detrimental effect on granulocyte-macrophage colony formation. Therefore, these findings suggest that gene therapy for RPS19-deficient patients with DBA using viral vectors that express the RPS19 gene is feasible. (Blood. 2002;100:2724-2731) (Less)
