Copper depletion boosts CNS leukemia therapy by inhibiting nucleotide synthesis through impairment of mitochondrial complex IV activity.

Depleting copper in leukemia cells weakens their energy production and makes them respond better to treatment in early laboratory studies.

This Nature Cancer preclinical study demonstrates that copper depletion potentiates CNS leukemia therapy by impairing mitochondrial complex IV activity, which restricts nucleotide synthesis in leukemia cells and sensitizes them to treatment. While mechanistically compelling in mouse models, translation to human CNS leukemia requires Phase 1 investigation.

Why it surfaced

Nat Cancer (high-impact), deferred from 2026-05-28 run. Preclinical only; non-human cap applied (max 5/10). Copper depletion mechanism is novel and CNS leukemia has high unmet need. Score capped at 5 per non-human scoring rule.
