GLI1-VENTX Expression Pattern as a Prognostic Value for Non-Metastatic Early Esophageal Squamous Cell Carcinoma

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Cell signaling pathways are crucial for biological processes, including tumorigenesis.
• Gene interactions within signaling pathways significantly influence cancer development and progression.
• Esophageal squamous cell carcinoma (ESCC) is a malignancy where such interactions are critical.

Purpose of the Study:

• To investigate the combined expression of GLI1 and VENTX genes in ESCC.
• To assess the relationship between GLI1 and VENTX expression and ESCC clinicopathological features.
• To explore the potential role of VENTX in activating GLI1 expression via the BMP pathway in ESCC.

Main Methods:

• Quantitative real-time reverse transcription polymerase chain reaction (RT-qPCR) was used to measure GLI1 and VENTX mRNA levels.
• Expression levels were compared between 50 ESCC tumor samples and adjacent normal tissues.
• Statistical analyses were performed to determine correlations between gene expression and clinicopathological features.

Main Results:

• A significant positive correlation was found between GLI1 and VENTX mRNA expression in ESCC patients (P < 0.05).
• GLI1 expression was notably higher in ESCC samples with elevated VENTX expression.
• The correlation between VENTX and GLI1 was significant in early-stage, non-metastatic ESCC (Stages I and II).

Conclusions:

• The concomitant expression of GLI1 and VENTX is significantly correlated in ESCC, especially in early stages.
• This suggests that combined GLI1 and VENTX expression may serve as a valuable biomarker for early ESCC detection.
• VENTX may activate GLI1 expression through the BMP pathway, potentially contributing to an aggressive ESCC phenotype.
