Mechanisms promoting physiological cells progression into tumorigenesis

Area of Science:

• Oncology
• Molecular Biology
• Drug Discovery

Background:

• Cancer remains a leading global cause of death, necessitating research into its underlying biology.
• Cancer stem cells (CSCs) are crucial for tumor maintenance and therapeutic resistance.
• The tumor microenvironment, including stromal cells and signaling pathways like WNT/β-catenin, significantly influences CSC behavior and epithelial-to-mesenchymal transition (EMT).

Purpose of the Study:

• To explore the role of CSCs and their niche in tumor development and therapy resistance.
• To investigate the link between WNT signaling, EMT, and CSCs.
• To propose a novel therapeutic strategy targeting CSCs and EMT.

Main Methods:

• Review of existing literature on cancer stem cells, WNT signaling, EMT, and the tumor microenvironment.
• Analysis of the interplay between CSCs, niche, and signaling pathways.
• Conceptualization of novel compound design integrating silanols and selenium.

Main Results:

• CSCs are central to tumor initiation, progression, and resistance.
• The WNT/β-catenin pathway and EMT are key processes in CSC maintenance and tumor growth.
• The tumor niche protects CSCs and promotes resistance to therapy.

Conclusions:

• A deeper understanding of CSCs, their niche, and associated pathways like WNT/EMT is vital for cancer treatment.
• Novel therapeutic approaches targeting CSCs and EMT are needed.
• Combining silanols (EMT inhibitors) with selenium agents (targeting CSCs) presents a promising direction for developing new anti-cancer drugs.
