Assessment of TSPO Gene Expression Levels in Colorectal Cancer Tumors: A Paired Sample Study

Area of Science:

• Oncology
• Molecular Biology
• Biomarker Discovery

Background:

• Colorectal cancer (CRC) is a leading cause of cancer mortality, with advanced stages often presenting metastatic challenges.
• Early detection via screening is vital for improving CRC patient outcomes.
• Investigating novel biomarkers for CRC diagnosis and prognosis is critical.

Purpose of the Study:

• To evaluate Translocator Protein (TSPO) gene expression in colorectal cancer tissues.
• To determine if TSPO expression correlates with invasive behavior, diagnosis, or prognosis in CRC patients.
• To explore TSPO as a potential biomarker for colorectal cancer.

Main Methods:

• A case-control study involving 25 colorectal tumor tissues and 25 adjacent non-tumor tissues.
• RNA extraction followed by Real-Time Polymerase Chain Reaction (RT-PCR) to quantify TSPO gene expression.
• Statistical analysis using Relative Expression Software Tool (REST) and SPSS version 24.

Main Results:

• TSPO gene expression was significantly higher in colorectal tumor tissues compared to normal tissues (p < 0.001).
• Elevated TSPO expression showed a significant association with higher tumor grade (p < 0.05).
• No significant differences in TSPO expression were observed based on sex or age.

Conclusions:

• TSPO gene expression is upregulated in colorectal tumor tissues and correlates with tumor grade.
• These findings indicate a potential role for TSPO in colorectal cancer development and progression.
• TSPO may serve as a valuable biomarker for CRC diagnosis and prognosis, particularly in clinical research.
