Metabolic reprogramming of the tumour microenvironment

Area of Science:

• Oncology
• Cancer Metabolism
• Tumour Microenvironment

Background:

• The tumour microenvironment comprises tumour cells, stromal cells, and the stroma.
• Metabolic reprogramming occurs in tumour cells and stromal cells like cancer-associated fibroblasts and tumour-associated macrophages.
• Stromal cells contribute to tumour progression and metastasis via secreted factors and metabolites.

Purpose of the Study:

• To summarize recent findings on metabolic reprogramming mechanisms.
• To elucidate the roles of metabolic reprogramming in cancer cells, cancer-associated fibroblasts, and tumour-associated macrophages.
• To highlight the impact of these metabolic changes on tumour progression and metastasis.

Main Methods:

• Literature review of current studies on cancer metabolism.
• Analysis of metabolic reprogramming mechanisms in various tumour cell types.
• Investigation of the role of intermediate metabolites and secreted factors.

Main Results:

• Metabolic reprogramming is a key feature of tumour cells and stromal components.
• Cancer-associated fibroblasts and tumour-associated macrophages exhibit altered metabolism.
• Stromal cell-derived metabolites and cytokines promote tumour growth and spread.

Conclusions:

• Metabolic reprogramming in the tumour microenvironment is integral to cancer progression.
• Targeting metabolic pathways in both tumour and stromal cells offers therapeutic potential.
• Further research into these mechanisms can lead to novel anti-cancer strategies.
