Metabostemness: a new cancer hallmark

Area of Science:

• Oncology
• Metabolic Regulation
• Epigenetics

Background:

• Cancer stemness is crucial for tumor initiation and progression.
• Genetic factors alone do not fully explain the acquisition of stemness.
• The cellular metabotype plays a key role in establishing cancer stemness traits.

Purpose of the Study:

• To introduce and define the concept of 'metabostemness'.
• To explore the role of metabolic parameters in cancer stem cell (CSC) acquisition.
• To propose metabostemness as a new framework for cancer drug discovery.

Main Methods:

• Conceptual framework development.
• Analysis of metabolic and epigenetic reprogramming in cancer.
• Literature review on cancer stem cell biology and metabolism.

Main Results:

• Metabostemness describes metabolic control over epigenetic reprogramming towards CSC states.
• Metabolic alterations can lower barriers to epigenetic rewiring, facilitating dedifferentiation.
• Metabostemness provides a targetable hallmark for cancer stemness.

Conclusions:

• Metabolism is a critical regulator of cancer stemness, alongside genetics.
• Targeting metabostemness offers a novel strategy for precision cancer medicine.
• This concept shifts oncology theory towards metabolo-epigenetic approaches.
