The granulocyte macrophage colony-stimulating factor (GM-CSF) is known to play a protective role in intestinal inflammation. However, the effects of GM-CSF on the progression of colitis to colorectal carcinoma have long remained unclear. We have recently demonstrated that GM-CSF produced by colonic epithelial cells promotes colorectal tumorigenesis by stimulating the secretion of vascular endot...

Suramin and suramin analogues strongly inhibit both nucleotide interaction with the nucleotide-binding site of granulocyte-macrophage colony-stimulating factor (GM-CSF) and bioactivity of the molecule as assessed by competition photoaffinity labeling and cell proliferation assay, respectively. The half-maximal inhibition of cell proliferation by suramin occurs at 68 +/- 2.5 microM; three surami...

We assessed the capacity of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) and multilineage (Multi)-CSF to induce release of granulocyte-CSF (G-CSF) by highly purified peripheral blood monocyte (Mo) preparations. Our results reveal that GM-CSF and Multi-CSF, either alone or in a synergistic concert, activate Mo to transcribe G-CSF messenger (m) RNA and release biolo...

The crystal structure of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) has been refined against data extending to a resolution of approximately 2.4 A along a* and approximately 1.9 A along b* and c*. Anisotropic scale factors of B11 = -20.8 A2, B22 = 7.4 A2, B33 = 13.3 A2 corrected for the more rapid fall of diffraction in the a* direction. The anisotropy correla...

Therapy combining dinutuximab with granulocyte macrophage colony stimulating factor, interleukin 2, and isotretinoin has significant side effects; however, these complications are generally predictable and can be managed proactively.

The effect of a panel of recombinant human (rh) cytokines on the generation of human eosinophil precursors was assessed using a two-step culture technique. Normal human bone marrow was preincubated with different cytokine combinations in liquid culture before assessment of the number of eosinophil progenitors, which give rise to eosinophil colony-forming units (CFU-Eo) on secondary semi-solid c...
