Target Background

(From Uniprot)
May promote proliferation of pancreatic cancer cells by favoring the transition from the S to G2/M phase. In myeloid leukemic cell lines, inhibits cell growth and induces cell differentiation and apoptosis. May play a role in the inhibition of EIF4EBP1 phosphorylation/deactivation. Facilitates cell adhesion, most probably through interaction with cell surface lectins and cadherin.
Gene References into Functions
  1. Study results suggest that OLFM4, LY6D and S100A7 immunoreactivity are associated with an aggressive phenotype of estrogen receptor (ER)-positive breast carcinoma, and these are potent markers for distant metastasis of ER-positive breast cancer patients. PMID: 30137688
  2. these data propose that hCG is not a key regulator of cellular alterations within peripheral blood dendritic cells PMID: 29488661
  3. discovered that OLFM4, CD11b, and ITGA2 are proteins that are overexpressed in both primary colon tumors and liver metastasis. These are colon cancer biomarkers with autoantigenic properties. PMID: 28669815
  4. MiR-103 acts as an oncogene miRNA to promote triple-negative breast cancer cells migration and invasion through targeting OLFM4. PMID: 28320108
  5. OLFM4 has an important role in the regulation of intestinal inflammation and tumorigenesis, and could be a potential therapeutic target for intestinal malignant tumors. Unlike the human colonic epithelium, the mouse colonic epithelium does not express OLFM4, but nevertheless, systemic OLFM4 deletion promotes colon tumorigenesis and that loss from mucosal neutrophils may have a role to play. PMID: 26973250
  6. Olfactomedin-4 identifies a subpopulation of neutrophils in patients with septic shock, and those with a high percentage of olfactomedin-4+ neutrophils are at higher risk for greater organ failure burden and death. Olfactomedin-4 might serve as a marker of a pathogenic neutrophil subset in patients with septic shock PMID: 27635771
  7. OLFM4 is proved to as a functional target for miR-590. PMID: 28012926
  8. Olfactomedin 4 is a novel tumor marker for triple-negative breast cancer for predicting and prognosis. PMID: 27939521
  9. OLFM4 is downregulated by miR-486-5p, which contributes to ovarian cancer tumorigenesis. Conversely, estrogen receptor signaling downregulates miR-486-5p and upregulates OLFM4 expression, slowing the development and progression of ovarian cancer. PMID: 26871282
  10. Data show that olfactomedin 4 (OLFM4) is highly expressed in proliferating benign epithelial cells and in some carcinoma cells. PMID: 26416558
  11. olfactomedin 4 appears to play a critical role in regulating progression of prostate cancer, and has potential as a new biomarker for prostate cancer. PMID: 26581960
  12. Study demonstrates that epigenetic silencing of OLFM4 enhances gastric cancer cell invasion via activation of FAK signaling. PMID: 26303970
  13. suppression of OLFM4 expression may be a promising strategy in the development of novel cancer therapeutic drugs PMID: 26398045
  14. Patients with an OLFM4 gene expression level above -7.5 were 6 times more likely to develop severe disease, after correction for age at hospitalization and gestational age. PMID: 26162090
  15. Using a human vaginal epithelial cell line, the expression of mucin 5 subtype B and olfactomedin-4 were down-regulated in response to N9, suggesting these markers could apply to humans PMID: 25333937
  16. findings suggest that OLFM4 is not only involved in early stages of gastric carcinogenesis but also a useful prognostic marker for advanced gastric cancer PMID: 26070873
  17. OLM4 expression is increased in the early stages of gastric, colorectal, and pancreatic cancer initiation. PMID: 25400027
  18. High expression of GW112 in colorectal cancer tissues and reduced expression of GRIM-19 in colorectal cancer tissues may be associated with abnormal proliferation of cancer cells. PMID: 26011333
  19. although low OLFM4 expression is not an independent prognostic biomarker, it might indicate worse prognosis for smoking patients with non-small cell lung cancer PMID: 25771901
  20. Impairment of ERalpha signal-mediated OLFM4 expression promoted the malignant progression of endometrioid adenocarcinoma. PMID: 24495253
  21. OLFM4 is a novel candidate tumor-suppressor gene for chromosome 13q and may shed new light on strategies that could be used for the diagnosis, prognosis, and treatment of prostate cancer patients. PMID: 24070418
  22. Reduced expression of olfactomedin 4 and ectopic expression of claudin-18 might be useful markers in the differential diagnosis of serrated polyps. PMID: 23570326
  23. OLFM4 is overexpressed in active IBD and secreted into mucus. OLFM4 seems to be of functional relevance in IBD as a mucus component, possibly by binding defensins. PMID: 22398066
  24. OLFM4 regulates host defense against a broad range of bacteria including Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli in an OLFM4-deficient mouse model. PMID: 22844115
  25. depletion of OLFM4 significantly inhibits tumorigenicity of the gastric cancer SGC-7901 and MKN45 cells. Blocking OLFM4 expression can sensitize gastric cancer cells to H2O2 or TNF alpha treatment by increasing caspase-3 dependent apoptosis. PMID: 22471589
