Metabolomic Profiling Reveals Key Metabolic Alterations in MCF7 Tamoxifen-Resistant Cells Following EPAS1 Inhibition

Tamoxifen (TAM) is a frontline therapy for luminal A breast cancer, yet acquired resistance poses a significant clinical challenge. This study investigates the molecular and metabolic basis of TAM resistance in MCF7/Tam1 cells, focusing on EPAS1 (HIF-2α)-driven hypoxia-induced metabolic reprogrammin...
