Targeting CAF-specific metabolic pathways in breast cancer

Area of Science:

• Oncology
• Cancer Metabolism
• Tumor Microenvironment

Background:

• Breast cancer (BC) cells exhibit metabolic plasticity to thrive in challenging tumor microenvironments (TME).
• Metabolic alterations in BC, such as the Warburg effect and modified oxidative phosphorylation, are linked to tumor-stroma signaling.
• Cancer-associated fibroblasts (CAFs) within the TME significantly impact cancer cell metabolism.

Purpose of the Study:

• To review and consolidate current knowledge on metabolic interactions between breast cancer cells and CAFs.
• To highlight the molecular mechanisms underlying these metabolic crosstalks.
• To identify potential therapeutic targets based on these interactions.

Main Methods:

• Literature review of recent research on breast cancer cell and CAF metabolic interplay.
• Analysis of molecular pathways involved in glucose, amino acid, and lipid metabolism.
• Synthesis of data on how these interactions influence tumor growth, invasion, and treatment resistance.

Main Results:

• Metabolic reprogramming is crucial for BC cell adaptation and survival in the TME.
• CAFs actively modulate BC cell metabolism, affecting key pathways.
• The metabolic crosstalk between BC cells and CAFs promotes tumor progression and confers resistance to therapies.

Conclusions:

• Metabolic interactions between BC cells and CAFs are critical drivers of breast cancer.
• Targeting these metabolic pathways presents a promising strategy for novel BC therapies.
• Further research into these interactions could lead to more effective treatment approaches.
