Adapt and shape: metabolic features within the metastatic niche

Area of Science:

• Oncology
• Cancer Biology
• Metabolism

Background:

• Metabolic factors significantly influence the success of disseminating cancer cells (DTCs) at specific metastatic sites.
• The primary tumor can metabolically condition distant organs, creating a premetastatic niche before DTCs arrive.
• DTCs also adapt their metabolism to survive the metastatic journey and colonize target organs.

Purpose of the Study:

• To review how cancer cells interact with the metabolic environment of target organs.
• To explore the dual strategies cancer cells employ to shape or adapt to tissue metabolism for metastasis.
• To highlight the underestimated role of target organ metabolism in metastatic fate.

Main Methods:

• Literature review of existing studies on cancer cell metabolism and metastasis.
• Analysis of metabolic interplay between primary tumors, DTCs, and metastatic microenvironments.
• Synthesis of findings on cancer cell strategies for metabolic adaptation and tissue shaping.

Main Results:

• Cancer cells utilize distinct metabolic strategies to colonize target tissues.
• These strategies involve both altering the host tissue's metabolism and adapting their own metabolic pathways.
• Successful colonization relies on creating a metabolically favorable environment for tumor growth.

Conclusions:

• Metabolic reprogramming is crucial at multiple stages of cancer metastasis.
• Both the origin (primary tumor) and the destination (target organ) play significant metabolic roles.
• Understanding these metabolic dynamics offers potential therapeutic targets for preventing or treating metastasis.
