Summary
Prostate-specific antigen (PSA) glycosylation offers potential as a biomarker for prostate cancer. Investigating PSA N-glycosylation profiles using separation-based methods is crucial for improving diagnostic accuracy.
Area of Science:
- Biochemistry
- Oncology
- Analytical Chemistry
Background:
- Prostate cancer is the most common cancer in men globally.
- Current prostate-specific antigen (PSA) tests have high false positive rates, necessitating improved diagnostic biomarkers.
- Altered PSA glycosylation may serve as a valuable marker for distinguishing malignant from benign prostate tumors.
Purpose of the Study:
- To review current bioanalytical strategies for investigating PSA N-glycosylation.
- To highlight challenges and trends in PSA glycobiomarker research.
- To focus on separation-based characterization methods for PSA glycosylation.
Main Methods:
- Critical review of existing literature on PSA glycosylation analysis.
