Target Background

Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. This CSF induces granulocytes.
Gene References into Functions
  1. G-CSF and IL-6 concentrations may be predictive of the onset of neonatal Leukemoid reaction. PMID: 29459579
  2. we described the construction and characterization of three G-CSF dimeric proteins generated using different linker peptides. GCSF-Lalpha had the best performance in terms of purity and in vitro activity PMID: 28721592
  3. this study shows that cortisol inhibits CSF3 via DNA methylation and inhibits invasion in first-trimester trophoblast cells PMID: 28846166
  4. We propose that in aggressive pancreatic ductal adenocarcinoma , elevated G-CSF contributes to tumor progression through promoting increases in infiltration of neutrophil-like cells with high immunosuppressive activity. Such a mechanism provides an avenue for a neoadjuvant therapeutic approach for this devastating disease PMID: 28775207
  5. conclusion, there was an elevated lipolysis condition within the FF of Polycystic Ovary Syndrome (PCOS) with metabolic syndrome (MS) patients and the TNF-alpha and G-CSF levels in FF were associated with top-quality embryo percentage. PMID: 28082237
  6. a set of IL-17A-regulated genes in keratinocytes, which recapitulate typical psoriasis genes exemplified by DEFB4A, S100A7, IL19 and CSF3, based on the differences in the expression profiles of cells stimulated with six cytokines versus cells stimulated with only five cytokines lacking IL-17A. PMID: 26944069
  7. The results showed that the addition of recombinant IL-1 markedly increased G-CSF expression in fibroblasts; however, IL-1 receptor antagonist only partially abrogated KCM-stimulated G-CSF expression, indicating the role of additional keratinocyte-releasable factors PMID: 27340768
  8. Data reviewed establish that any damage to brain tissue tends to cause an increase in G-CSF and/or GM-CSF (G(M)-CSF) synthesized by the brain. Glioblastoma cells themselves also synthesize G(M)-CSF. G(M)-CSF synthesized by brain due to damage by a growing tumor and by the tumor itself stimulates bone marrow to shift hematopoiesis toward granulocytic lineages away from lymphocytic lineages. PMID: 28459367

  14. Cancer cells can produce IL-18, which is involved in the process of angiogenesis, stimulates invasion and metastasis.

  15. G-CSF showed favorable effects only on the migration of HUVECs, and no direct influence was found on Osteoblasts. PMID: 27006951
  16. tumor G-CSF expression is an indicator of an extremely poor prognosis in cervical cancer patients that are treated with chemotherapy. PMID: 26666576
  17. G-CSF stimulates beta1 integrin expression and Swan 71 cell migration by activating PI3K and MAPK signaling pathways. PMID: 26992288
  18. these data suggest that G-CSF may contribute to tumor growth and decrease the antitumor effect of radiotherapy, possibly by promoting vascularization in cancer lesions. PMID: 25976379
  19. in vitro chemotaxis assays and an in vivo transplantation model for chemoattraction confirmed that UCX((R)) are chemotactic to CD34(-)/CD45(-) BM-MSCs via a cell-specific mobilization mechanism mediated by G-CSF. PMID: 24480602
  20. Case Report: undifferentiated colon carcinoma producing G-CSF. PMID: 25400792

  28. The results demonstrated that 3DHSA-G-CSF has the ability to increase the peripheral white blood cell (WBC) counts of neutropenia model mice, and the half-life of 3DHSA-G-CSF is longer than that of native G-CSF. PMID: 24151579
