PYGO2 regulates IL10 and plays immunosuppressive role through ESCC progression

Area of Science:

• Oncology
• Molecular Biology
• Gastroenterology

Background:

• Esophageal squamous cell carcinoma (ESCC) is an aggressive cancer with high mortality.
• The Wnt pathway is crucial for cell proliferation and differentiation.
• PYGO2 and IL10 are key players in the Wnt pathway.

Purpose of the Study:

• To investigate the correlation between PYGO2 and IL10 expression in ESCC.
• To analyze the relationship between gene expression and clinicopathological features.
• To explore the functional interaction between PYGO2 and IL10 in ESCC.

Main Methods:

• Real-time quantitative PCR (RT-qPCR) to assess PYGO2 and IL10 mRNA levels in ESCC tissues and cell lines.
• Induction of PYGO2 expression in ESCC cell lines (KYSE-30, YM1) to observe effects on IL10.
• Statistical analysis to correlate gene expression with tumor differentiation and invasion depth.

Main Results:

• Significant overexpression of PYGO2 (31.0%) and IL10 (51.7%) mRNA observed in ESCC.
• PYGO2 and IL10 overexpression showed a significant positive correlation (p=0.007).
• Concomitant overexpression linked to higher tumor grade and invasion depth (p<0.01, p<0.05).
• Induced PYGO2 expression altered IL10 levels in ESCC cells.

Conclusions:

• PYGO2 may regulate IL10 via the Wnt/β-catenin pathway, indicating a potential oncogenic role for the PYGO2/IL10 axis in ESCC.
• The interaction between PYGO2 and IL10 might promote invasion and malignancy in ESCC.
• Targeting the PYGO2/IL10 axis could offer new therapeutic strategies for ESCC.
