Coupling Metabolic Niche Normalization with Reinstatement of the NR2F1 Dormancy Program: A Mechanistic Hypothesis for Durable Non-Chemotherapeutic Control of Breast Cancer Metastasis
A mechanistic hypothesis for durable, non-chemotherapeutic control of breast cancer metastasis, combining two complementary strategies: metabolic niche normalization through inhibition of the monocarboxylate transporters MCT1 and MCT4, and pharmacological reactivation of the NR2F1 dormancy program. The work proposes that metastatic outgrowth is governed by a metabolic–epigenetic switch, and that normalizing the acidic, lactate-rich tumor microenvironment while reinstating NR2F1-mediated dormancy may stabilize disseminated tumor cells in long-term quiescence. It integrates published evidence into a unified framework and sets out falsifiable predictions for testing in cell lines, organoids, and animal models.
