Emerging Proteins in CRPC: Functional Roles and Clinical Implications.

Area of Science:

• Oncology
• Biochemistry
• Molecular Biology

Background:

• Prostate cancer (PCa) is a prevalent malignancy in men, often leading to overtreatment due to a lack of specific diagnostic markers.
• Progression to castration-resistant prostate cancer (CRPC) presents significant clinical challenges.
• Identifying novel biomarkers is crucial for accurate diagnosis and effective management of CRPC.

Purpose of the Study:

• To systematically review emerging protein markers associated with the progression of prostate cancer from castration-sensitive (CSPC) to castration-resistant (CRPC).
• To analyze the role of these proteins in CRPC growth, invasion, metastasis, metabolism, and the immune microenvironment.
• To summarize the molecular regulatory mechanisms and clinical applications of these novel protein markers.

Main Methods:

• Systematic review of scientific literature.
• Analysis of protein expression patterns in tissue, cell lines, and serum during CSPC to CRPC transition.
• Evaluation of molecular mechanisms and clinical utility of identified protein markers.

Main Results:

• Emerging proteins exhibit altered expression patterns during prostate cancer progression to CRPC.
• These proteins are implicated in key CRPC pathobiological processes, including growth, invasion, and immune modulation.
• Understanding their regulatory mechanisms provides insights into CRPC development.

Conclusions:

• Novel protein markers hold significant potential for diagnosing and managing CRPC.
• These markers can serve as diagnostic, prognostic, predictive, and therapeutic targets.
• Further research into these proteins may lead to improved clinical outcomes for prostate cancer patients.
