Human granulocyte-macrophage colony-stimulating factor (hGM-CSF) stimulates primitive and definitive erythropoiesis in mouse embryos expressing hGM-CSF receptors but not erythropoietin receptors.
Although erythropoietin (EPO) and its receptor (EPOR) are crucial for the proliferation, survival, and terminal differentiation of erythroid progenitors, it remains to be elucidated whether EPOR-unique signaling is required for erythropoiesis. To address this issue, human granulocyte-macrophage colony-stimulating factor (hGM-CSF) receptor (hGMR)-transgenic mice and heterozygous EPOR mutant mice...
متن کاملIMPROVEMENT OF hGM-CSF EXPRESSION USING A FUSION SYSTEM BY DIRECTING PROTEIN TO THE PERIPLASMIC SPACE
Bacterial expression systems provide economic and logistic advantages in manufacturing proteins for human therapeutic purposes. However, most such proteins accumulate in insoluble biologicaIIy inactive form when overexpressed in bacterial cells. This is the case while attempting to produce recombinant human granulocyte-macrophage colony stimulating factor (hGM-CSF) in E. coli. In this repor...
متن کاملEstablishment and characterization of gastric carcinoma cell clones expressing LMP2A of Epstein-Barr virus.
Although Epstein-Barr virus (EBV) has been detected in 5-15% of gastric carcinoma (GC) cases, the mechanism by which EBV contributes to its tumorigenesis remains unclear. Only a subset of EBV latent proteins such as EBV nuclear antigen-1 and latent membrane protein 2A (LMP2A) are expressed in EBV-associated GC (EBVaGC) cases. In this study, to elucidate the role of LMP2A in the tumorigenesis of...
متن کاملG-CSF receptor positive neuroblastoma subpopulations are enriched in chemotherapy-resistant or relapsed tumors and are highly tumorigenic.
Neuroblastoma is a neural crest-derived embryonal malignancy, which accounts for 13% of all pediatric cancer mortality, primarily due to tumor recurrence. Therapy-resistant cancer stem cells are implicated in tumor relapse, but definitive phenotypic evidence of the existence of these cells has been lacking. In this study, we define a highly tumorigenic subpopulation in neuroblastoma with stem c...
متن کاملHuman granulocyte-macrophage colony-stimulating factor (hGM-CSF) induces inhibition of intrathymic T-cell development in hGM-CSF receptor transgenic mice.
Thymocytes show differential cytokine responses, depending on the stage of differentiation. Whether these responses are due to preferential cytokine receptor expression or due to downstream signaling mechanisms is unknown. In this study, we examined the relationship between receptor expression and T-cell proliferation or differentiation using thymocytes from transgenic mice constitutively expre...
