Summary of "Expression and Association of Tumor Necrosis Factor Receptor Associated Factor 4 (TRAF4) in Esophageal Squamous Cell Carcinoma."

BACKGROUND At present, there is no effective targeted therapy for esophageal squamous cell carcinoma (ESCC), and it is urgent to find new targets for the treatment of ESCC. TRAF4 has been regarded as a cause of carcinogenesis due to overexpression in many cancer types and participation in multiple signaling pathways. However, there are few studies on TRAF4 in ESCC worldwide. Its expression in ESCC and whether it affects the prognosis of patients still remain unclear. MATERIAL AND METHODS We detected the expressions of TRAF4, ki-67, and p53 in 100 cases of ESCC and 80 cases of adjacent normal esophageal squamous epithelium tissues by immunohistochemical technique. We further explored the relationship between TRAF4 and ESCC and its prognosis through statistical analysis. RESULTS TRAF4 was highly expressed in ESCC tissues and was mainly expressed in the cytoplasm. Overexpression of TRAF4 in ESCC was also associated with high expression of ki-67 and p53 (P<0.05). We also found that patients with high expression of TRAF4 had significantly lower OS than in patients with low TRAF4 expression (P<0.05). Overexpression of TRAF4 was an independent risk factor affecting the prognosis of patients (P<0.05). CONCLUSIONS We found that TRAF4 was highly expressed in ESCC tissues and was mainly expressed in the cytoplasm of cancer cells. Overexpression of TRAF4 was an independent risk factor affecting the overall prognosis of patients. The results indicated that TRAF4 may become a new target for the treatment of ESCC in the future.

Medical and Biotech [MESH] Definitions

A novel member of the tumor-necrosis factor receptor family that can also mediate HERPES SIMPLEX VIRUS TYPE 1 entry into cells. It has specificity for TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 14 and the homotrimeric form of LYMPHOTOXIN-ALPHA. The receptor is abundantly expressed on T-LYMPHOCYTES and may play a role in regulating lymphocyte activation. Signaling by the activated receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.

A tumor necrosis factor receptor subtype that has specificity for TUMOR NECROSIS FACTOR ALPHA and LYMPHOTOXIN ALPHA. It is constitutively expressed in most tissues and is a key mediator of tumor necrosis factor signaling in the vast majority of cells. The activated receptor signals via a conserved death domain that associates with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM.

A member of the tumor necrosis factor receptor superfamily found on mature B-LYMPHOCYTES. It has specificity for B CELL ACTIVATING FACTOR and TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 13. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.

A secreted tumor necrosis factor receptor family member that has specificity FAS LIGAND and TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 14. It plays a modulating role in tumor necrosis factor signaling pathway.

A tumor necrosis factor receptor subtype with specificity for TUMOR NECROSIS FACTOR LIGAND SUPERFAMILY MEMBER 15. It is found in tissues containing LYMPHOCYTES and may play a role in regulating lymphocyte homeostasis and APOPTOSIS. The activated receptor signals via a conserved death domain that associates with specific TNF RECEPTOR-ASSOCIATED FACTORS in the CYTOPLASM.
