Abstract:
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.
Insights
Tumor necrosis factor receptor-associated factor 4 (TRAF4) is overexpressed in esophageal squamous cell carcinoma (ESCC), correlating with poor prognosis. This finding suggests TRAF4 may be a potential therapeutic target for ESCC treatment.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Esophageal squamous cell carcinoma (ESCC) lacks effective targeted therapies, necessitating novel treatment targets.
- Tumor necrosis factor receptor-associated factor 4 (TRAF4) is implicated in various cancers but its role in ESCC remains understudied.
- Understanding TRAF4 expression and its prognostic significance in ESCC is crucial.
Purpose of the Study:
- To investigate the expression levels of TRAF4 in ESCC tissues compared to normal esophageal epithelium.
- To determine the correlation between TRAF4 expression and clinicopathological features, including proliferation markers (ki-67) and tumor suppressor protein (p53).
- To evaluate the prognostic value of TRAF4 expression in patients with ESCC.
Main Methods:
- Immunohistochemical analysis was performed to detect TRAF4, ki-67, and p53 expression in 100 ESCC and 80 adjacent normal esophageal tissues.
- Statistical analyses were employed to assess the relationships between TRAF4 expression and clinicopathological parameters, as well as patient overall survival (OS).
Main Results:
- TRAF4 was significantly overexpressed in ESCC tissues, predominantly in the cytoplasm.
- High TRAF4 expression correlated with increased ki-67 and p53 levels in ESCC.
- Patients with high TRAF4 expression exhibited significantly poorer overall survival (OS) compared to those with low expression.
- TRAF4 overexpression was identified as an independent risk factor for poor prognosis in ESCC.
Conclusions:
- TRAF4 is highly expressed in ESCC and its overexpression is linked to poor patient prognosis.
- TRAF4 may serve as a potential novel therapeutic target for esophageal squamous cell carcinoma.
- Further research into TRAF4's role could lead to targeted treatment strategies for ESCC.
