Endothelin-1, a potent vasoconstrictor, plays an important role in pulmonary hypertension (PH) in sickle cell disease (SCD). Our previous studies show that higher levels of placenta growth factor (PlGF), secreted by erythroid precursor cells, correlate with increased plasma levels of endothelin-1 (ET-1) and other functional markers of PH in SCD.(More)
Placental growth factor (PlGF) plays an important role in various pathological conditions and diseases such as inflammation, cancer, atherosclerosis and sickle cell disease (SCD). Abnormally high PlGF levels in SCD patients are associated with increased inflammation and pulmonary hypertension (PHT) and reactive airway disease; however, the transcriptional(More)
Beta protein 1 (BP1), a human homeotic transcription factor, is expressed during hematopoeisis in the erythroid lineage. To determine the in vivo role of BP1 in erythropoiesis, we have undertaken two complementary approaches using enforced BP1 expression in both transgenic mice and embryonic stem (ES) cells. Despite repeated attempts, only one adult(More)
The β-hemoglobinopathies and thalassemias are serious genetic blood disorders affecting the β-globin chain of hemoglobin A (α(2)β(Α)(2)). Their clinical severity can be reduced by enhancing expression of fetal hemoglobin (γ-globin), producing HbF (α(2)γ(2,)). In studies reported here, γ-globin induction by 23 novel, structurally-unrelated compounds, which(More)
