Metabolic Adaptations in Cancer Stem Cells.

Area of Science:

• Oncology
• Cancer Metabolism
• Cell Biology

Background:

• Cancer stem cells (CSCs) are a rare subpopulation responsible for tumor initiation, progression, and metastasis.
• CSCs exhibit inherent resistance to conventional therapies, leading to disease relapse.
• CSCs are found in various solid tumors, including melanoma, sarcoma, and colon cancer.

Purpose of the Study:

• To review the distinct metabolic pathways utilized by CSCs from different tumor types.
• To explore how metabolic reprogramming enables CSC survival under harsh conditions.
• To identify potential molecular targets within CSC metabolism for therapeutic intervention.

Main Methods:

• This review synthesizes current research on CSC metabolism.
• It analyzes diverse metabolic strategies, including aerobic glycolysis, oxidative phosphorylation, and fatty acid oxidation.
• The review discusses CSC adaptability to microenvironmental stresses like hypoxia and acidosis.

Main Results:

• CSCs display heterogeneous metabolic profiles, differing across tumor types.
• Fatty acid oxidation and ketone bodies are common energy sources for CSCs.
• CSCs can dynamically alter their metabolism to survive adverse conditions.

Conclusions:

• Targeting CSC-specific metabolic vulnerabilities presents a promising therapeutic strategy.
• Exploiting metabolic differences could lead to novel treatments for metastatic disease.
• Understanding CSC metabolism is crucial for overcoming therapeutic resistance and preventing cancer recurrence.
