Prostate cancer stem cell dynamics in the evolution of drug resistance

Area of Science:

• Oncology
• Cancer Stem Cell Biology
• Prostate Cancer Research

Background:

• Prostate cancer is a major cause of male mortality, complicated by tumor heterogeneity and therapy resistance.
• Androgen deprivation therapy (ADT) resistance often leads to castration-resistant prostate cancer (CRPC), potentially driven by prostate cancer stem cells (CSCs).
• Prostate CSCs contribute significantly to tumor heterogeneity, drug resistance, and disease recurrence.

Purpose of the Study:

• To synthesize current knowledge on the identity, regulation, and functional dynamics of prostate CSCs.
• To highlight the role of prostate CSCs in shaping the tumor ecosystem and driving therapeutic challenges.
• To discuss emerging strategies targeting CSC-specific vulnerabilities for improved prostate cancer treatment.

Main Methods:

• Review of current scientific literature on prostate cancer stem cells.
• Analysis of genetic, epigenetic, and microenvironmental factors influencing CSC behavior.
• Synthesis of information on therapeutic strategies targeting CSCs.

Main Results:

• Prostate CSCs exhibit adaptive self-renewal and regenerative capacities, contributing to heterogeneity and resistance.
• Genetic, epigenetic, and microenvironmental reprogramming enables CSC survival and adaptation under androgen deprivation.
• CSCs are pivotal in fostering clonal diversification and disease recurrence.

Conclusions:

• Prostate CSCs are critical drivers of advanced prostate cancer progression and therapeutic challenges.
• Targeting CSC-specific vulnerabilities, including stemness and plasticity drivers, is essential for novel therapies.
• Further unraveling prostate CSC biology is key to developing precision therapies against CSC-driven prostate diseases.
