🔬 Epigenetic Rewiring and Metabolic Vulnerability

Single-cell transcriptomics revealed that phenotypic switching relies heavily on the histone demethylase LSD1 (KDM1A). In casting off androgen dependence, the transformed cells develop an acute metabolic addiction to mitochondrial OXPHOS Complex I.

The Michigan team deployed a synergistic duo: the clinical LSD1 inhibitor seclidemstat combined with an electron transport chain inhibitor. This dual strike collapsed mitochondrial membrane potential, sparking lethal reactive oxygen species accumulation inside malignant cells.
