Functional Enrichment Analysis of Tumor Microenvironment-Driven Molecular Alterations That Facilitate...

Area of Science:

• Oncology
• Molecular Biology
• Cancer Research

Background:

• Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality worldwide.
• Tumor invasion and metastasis are critical processes in HCC progression, driven by complex interactions within the tumor microenvironment.
• Epithelial-to-mesenchymal transition (EMT) is a key phenomenon facilitating tumor cell invasion and metastasis.

Purpose of the Study:

• To investigate molecular differences in Epithelial-to-mesenchymal transition (EMT) gene expression between tumor border and core cells in Hepatocellular Carcinoma (HCC).
• To identify specific genes associated with tumor invasion and metastasis in HCC.
• To explore potential therapeutic targets for preventing distant metastasis in HCC patients.

Main Methods:

• Comparative analysis of gene expression profiles between HCC tumor border cells and internal tumor cells.
• Focus on key genes involved in the Epithelial-to-mesenchymal transition (EMT) pathway.
• Statistical analysis to determine significant differences in gene expression levels.

Main Results:

• Significant upregulation of NOTCH1, ID1, and LST1 gene expression was observed at the tumor border of HCC.
• These genes are implicated in promoting tumor cell invasion and the metastatic process.
• The findings highlight distinct molecular characteristics at the invasive front of HCC tumors.

Conclusions:

• NOTCH1, ID1, and LST1 are identified as key molecular players at the invasive edge of HCC.
• Targeting these upregulated genes presents a promising therapeutic strategy to inhibit HCC metastasis.
• This research contributes to understanding HCC progression and developing novel treatment approaches for improved patient outcomes.
