Hemoglobinopathies such as sickle cell anemia and b-thalassemia result from among the most common single gene defects worldwide. A promising approach for the treatment of these conditions is through the induction of increased fetal hemoglobin (HbF) expression. Hydroxyurea, which is currently part of the standard treatment of sickle cell anemia, causes increased expression of HbF. However, the l...
RNA polymerase II (RNAPII) transcription has been proposed to occur at transcription factories; nuclear focal accumulations of the active, phosphorylated forms of RNAPII. The low ratio of transcription factories to active genes and transcription units suggests that genes must share factories. Our previous analyses using light microscopy have indicated that multiple genes could share the same fa...
The molecular mechanisms governing γ-globin expression in a subset of fetal hemoglobin (α2γ2: HbF) expressing red blood cells (F-cells) and the mechanisms underlying the variability of response to hydroxyurea induced γ-globin expression in the treatment of sickle cell disease are not completely understood. Here we analyzed intra-person clonal populations of basophilic erythroblasts (baso-Es) de...
The level of fetal hemoglobin (HbF) modifies the severity of the common β-globin disorders. Knowledge of the normal mechanisms that repress HbF in the adult stage has remained limited until recently despite nearly 3 decades of molecular investigation, in part because of imperfect model systems. Recent studies have provided new insights into the developmental regulation of globin genes and ident...
Genetic polymorphisms in Quantitative Trait Loci (QTL) genes such as BCL11A, HBS1L-MYB and KLF1 have been reported to influence fetal hemoglobin (HbF) levels. This prospective study was planned evaluate the role of genetic QTL determinant HbF levels beta thalassemia major patients. The carried out on 100 Blood samples were collected EDTA plain vials for biochemical molecular evaluation. genotyp...
The Ufm1 conjugation system is an ubiquitin-like modification system that consists of Ufm1, Uba5 (E1), Ufc1 (E2), and less defined E3 ligase(s) and targets. The biological importance of this system is highlighted by its essential role in embryogenesis and erythroid development, but the underlying mechanism is poorly understood. UFBP1 (Ufm1 binding protein 1, also known as DDRGK1, Dashurin and C...
