Targeting Cancer Stem Cells: A Strategy for Effective Eradication of Cancer.

Area of Science:

• Oncology
• Cancer Biology
• Molecular Therapeutics

Background:

• Cancer stem cells (CSCs) drive tumor heterogeneity, recurrence, and metastasis.
• CSCs exhibit resistance to conventional chemotherapy, posing a significant therapeutic challenge.
• Targeting CSC-regulating pathways alongside conventional therapy is a promising strategy.

Purpose of the Study:

• To review therapeutic strategies for targeting cancer stem cells (CSCs) in various cancers.
• To discuss the role of YAP1 in regulating CSC phenotypes and its therapeutic potential.
• To explore the challenges and opportunities in developing CSC-targeting therapies.

Main Methods:

• Literature review of therapeutic strategies for CSCs.
• Analysis of preclinical and clinical data on CSC pathway inhibitors.
• Examination of YAP1's role in CSC regulation using cell lines and xenograft models.

Main Results:

• YAP1 plays a critical role in regulating CSC phenotypes in bladder cancer and lung adenocarcinoma.
• Inhibition of YAP1 enhances conventional therapy efficacy by reducing CSC stemness.
• Targeting CSC pathways shows potential in preclinical studies, with several inhibitors in clinical trials.

Conclusions:

• Targeting CSCs, particularly through YAP1 inhibition, can overcome drug resistance and improve conventional therapy outcomes.
• Combined therapeutic approaches targeting CSCs and their regulatory pathways offer a promising avenue for cancer treatment.
• Further research and clinical trials are needed to fully realize the potential of CSC-targeting therapies.
