• DPP3 is overexpressed in breast cancer tissues and correlates with poor patient survival, suggesting its potential as a prognostic biomarker.
• Knockout of DPP3 in breast cancer cell lines inhibits proliferation and migration while promoting apoptosis, indicating its oncogenic role.
• DPP3 stabilizes FASN, enhancing fatty acid synthesis and contributing to metabolic reprogramming in tumors.
• The DPP3-FASN interaction represents a novel therapeutic target for breast cancer treatment.
