TRIM29 prevents hepatocellular carcinoma progression by inhibiting Wnt/β-catenin signaling pathway

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Tripartite motif-containing protein 29 (TRIM29) is implicated in various cancers.
• Its specific role and mechanism in hepatocellular carcinoma (HCC) require further elucidation.

Purpose of the Study:

• To investigate the expression and function of TRIM29 in HCC.
• To explore the underlying molecular mechanisms of TRIM29's action in liver cancer.

Main Methods:

• Western blot and quantitative polymerase chain reaction (qPCR) to detect TRIM29 expression in HCC tissues and cell lines.
• Construction of TRIM29-knockdown and overexpression HCC cell models.
• In vitro assays to assess cell proliferation, clone formation, migration, and invasion.

Main Results:

• TRIM29 expression was significantly down-regulated in HCC samples and cell lines.
• Reduced TRIM29 levels correlated with lower HCC differentiation.
• TRIM29 depletion enhanced HCC cell proliferation, colony formation, migration, and invasion.
• These effects were associated with the Wnt/β-catenin signaling pathway.

Conclusions:

• TRIM29 functions as a tumor suppressor in HCC.
• Down-regulation of TRIM29 promotes HCC progression, potentially through the Wnt/β-catenin pathway.
• TRIM29 may serve as a potential therapeutic target for HCC.
