Correlation between FOXP3 expression and gastric cancer

Area of Science:

• Oncology
• Molecular Biology
• Gastroenterology

Background:

• Gastric cancer remains a significant global health challenge.
• Understanding the molecular mechanisms underlying gastric cancer pathogenesis is crucial for developing effective therapies.
• Forkhead box protein 3 (FOXP3) is a key regulator of immune responses and has been implicated in various cancers.

Purpose of the Study:

• To investigate the expression and functional role of FOXP3 in gastric cancer using a chemically induced rat model.
• To determine the correlation between FOXP3 expression levels and the grade of gastric lesions.

Main Methods:

• Gastric cancer was induced in Wistar rats using sarcosine ethyl ester hydrochloride and sodium nitrite.
• FOXP3 expression was analyzed using reverse transcription-polymerase chain reaction, immunoblotting, immunohistochemistry, and western blotting.
• Expression levels were compared between experimental (cancer) and control (normal) groups and correlated with lesion grades.

Main Results:

• FOXP3 transcription and expression were significantly higher in gastric cancer tissues compared to normal tissues (P<0.05).
• A positive correlation was observed between higher gastric lesion grades and increased FOXP3 expression levels (P<0.05).
• FOXP3 protein was primarily localized in the nuclei of tumor cells, with positive staining observed in 62.50% of gastric cancer tissues.

Conclusions:

• FOXP3 expression is upregulated in gastric cancer and positively correlates with disease progression and severity.
• FOXP3 may play a significant role in the occurrence and development of gastric cancer.
• Targeting FOXP3 could be a potential therapeutic strategy for gastric cancer.
