Implication

Perspective review explores Wnt/beta-catenin pathway dynamics in cancer stem cells, highlighting therapeutic opportunities and safety challenges for targeted cancer eradication.

Key Points

  • Synthesize current knowledge on the role of Wnt/beta-catenin signaling in cancer stem cells and evaluate the therapeutic feasibility of targeting this pathway.
  • Reviewed evolutionary conservation and physiological functions of Wnt pathways across embryonic development and adult tissue homeostasis.
  • Evaluated the molecular overlaps between normal somatic stem cell niches and cancer stem cells in tissues such as skin, blood, intestine, and brain.
  • Wnt/beta-catenin signaling critically governs cell proliferation, morphology, motility, and cell fate decisions in both healthy tissues and neoplasms.
  • Extensive molecular similarities between normal adult stem cells and cancer stem cells pose significant challenges for selective therapeutic targeting without dose-limiting toxicities.
  • Outlined strategic avenues for developing selective therapeutics capable of disrupting Wnt-driven oncogenesis while preserving homeostatic tissue maintenance.
