Targeting cancer stem cells for reversing therapy resistance: mechanism, signaling, and prospective agents

Area of Science:

• Oncology
• Cancer Biology
• Translational Medicine

Background:

• Cancer stem cells (CSCs) possess self-renewal and differentiation capabilities, driving tumor progression and therapeutic resistance.
• The precise mechanisms underlying CSC behavior and treatment failure remain incompletely understood.
• Identifying CSC hallmarks and resistance pathways is vital for refining treatment strategies and reducing cancer recurrence.

Purpose of the Study:

• To review the identification and characteristics of CSCs.
• To elucidate the intrinsic and extrinsic mechanisms of therapy resistance in CSCs.
• To explore CSC signaling pathways involved in treatment failure and discuss potential CSC-targeting agents.

Main Methods:

• Literature review of CSC identification and resistance mechanisms.
• Analysis of signaling pathways mediating CSC-driven treatment failure.
• Clinical perspective on CSC-targeting agents in various cancers.

Main Results:

• CSCs play a critical role in tumor progression and resistance to conventional therapies.
• Various intrinsic and extrinsic factors contribute to CSC therapy resistance.
• Specific signaling pathways are implicated in CSC-mediated treatment failure.

Conclusions:

• Targeting CSCs and their associated mechanisms offers a promising strategy for improving cancer therapy.
• Further research into CSC biology may lead to novel drug discovery and improved therapeutic regimens.
• Understanding CSCs is key to overcoming treatment resistance and reducing cancer relapse.
