Background:
The forkhead box A (FOXA) family has been extensively studied in cancer research; however, the role of FOXA3 in malignant tumors, particularly esophageal squamous cell carcinoma (ESCC), is not well understood. This study explores the expression and function of FOXA3 in ESCC, assessing its potential as a prognostic marker and therapeutic target.
Methods:
This study analyzed FOXA3 expression in ESCC tissues and its correlation with patient prognosis. The effects of FOXA3 overexpression on ESCC cell proliferation, migration, and invasion were examined in ESCC cell lines in vitro. Additionally, an in vivo tumorigenesis assay was performed using subcutaneous injection to assess the impact of FOXA3 overexpression on tumor growth. Statistical analyses were conducted to determine the significance of the results.
Results:
FOXA3 expression was significantly reduced in ESCC tissues compared with it in paired adjacent normal tissues, and low FOXA3 expression was significantly associated with poor prognosis in ESCC patients. FOXA3 overexpression markedly inhibited ESCC cell proliferation, migration, and invasion. In addition, overexpression of FOXA3 repressed tumor growth in mice.
Conclusions:
These findings indicate that FOXA3 acts as a tumor suppressor in ESCC, and its low expression is linked to poor outcomes. FOXA3 may serve as a potential diagnostic and therapeutic target for ESCC.
Insights
Forkhead box A3 (FOXA3) acts as a tumor suppressor in esophageal squamous cell carcinoma (ESCC). Low FOXA3 expression correlates with poor prognosis, suggesting its potential as a diagnostic and therapeutic target for ESCC.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- The role of the forkhead box A (FOXA) family in cancer is well-established, but FOXA3's specific function in esophageal squamous cell carcinoma (ESCC) remains unclear.
- This study investigates FOXA3 expression and its functional significance in ESCC development and progression.
Purpose of the Study:
- To determine the expression levels of FOXA3 in ESCC tissues.
- To evaluate the correlation between FOXA3 expression and patient prognosis.
- To elucidate the functional role of FOXA3 in ESCC cell behavior and tumor growth.
Main Methods:
- Analysis of FOXA3 expression in ESCC tissues and adjacent normal tissues.
- In vitro studies assessing the impact of FOXA3 overexpression on ESCC cell proliferation, migration, and invasion.
- In vivo tumorigenesis assay to evaluate FOXA3's effect on tumor growth.
Main Results:
- FOXA3 expression was significantly downregulated in ESCC tissues compared to normal tissues.
- Low FOXA3 expression was significantly associated with poorer patient prognosis.
- Overexpression of FOXA3 suppressed ESCC cell proliferation, migration, invasion, and in vivo tumor growth.
Conclusions:
- FOXA3 functions as a tumor suppressor in ESCC.
- Reduced FOXA3 expression is a marker of poor prognosis in ESCC patients.
- FOXA3 represents a potential diagnostic biomarker and therapeutic target for ESCC.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
