Association of the Δ Mutant Genotype with Sickle Cell Disease in Egyptian Patients.

Sickle cell disease is considered the most common single base mutation in the world, with >250,000 new patients being discovered each year. It consists of a wide spectrum of clinical presentations and complications. The is the mutant genotype of C-C chemokine receptor 5 (CCR5).

Role of Granulocyte-Macrophage Colony-Stimulating Factor in Acute Myeloid Leukemia/Myelodysplastic Syndromes.

Purpose: Granulocyte-macrophage colony-stimulating factor (GM-CSF) cytokine stimulates growth, differentiation, and function of myeloid progenitors. We aimed to study the role of GM-CSF gene expression, its protein, and antibodies in patients with acute myeloid leukemia/myelodysplastic syndromes (AML/MDS) and their correlation to disease behavior and treatment outcome. The study included 50 Egyptian patients with AML/MDS in addition to 20 healthy volunteers as control subjects.
