Ubiquitin B, Ubiquitin C, and β-Catenin as Promising Diagnostic and Prognostic Tools in Prostate Cancer

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Prostate cancer (PC) is a significant global health issue, ranking as the second most common malignancy.
• Ubiquitination is a key cellular process implicated in cancer development and progression.
• Understanding the roles of specific ubiquitin proteins and associated molecules is crucial for PC research.

Purpose of the Study:

• To investigate the expression profiles and clinical significance of ubiquitin B (UBB), ubiquitin C (UBC), and β-Catenin in prostate cancer.
• To determine the association of UBB, UBC, and β-Catenin expression with clinical and histopathological data in PC patients.
• To evaluate the potential of these molecules as prognostic markers for patient survival.

Main Methods:

• Analysis of UBB, UBC, and β-Catenin expression in PC tissues and lymph node metastases.
• Correlation of expression levels with clinical and histopathological data.
• Kaplan-Meier survival analysis to assess the impact on overall survival.

Main Results:

• UBB and UBC expression were upregulated in PC tissues, with higher levels in lymph node metastases.
• High UBB and UBC levels correlated with diminished overall survival in PC patients.
• Reduced membranous β-Catenin expression was observed in PC tissues and associated with shorter survival, acting as an independent prognostic factor.

Conclusions:

• UBB, UBC, and β-Catenin play significant roles in prostate cancer progression and patient outcomes.
• Simultaneous high UBB/UBC expression and aberrant β-Catenin expression indicate the poorest overall survival.
• Evaluating UBB, UBC, and β-Catenin collectively offers potential as robust prognostic markers for PC.
