A molecule designed to activate iron locked up in organelles called lysosomes and thereby induce cell death might offer a way to tackle treatment-resistant cancer.
A technique called condense-seq has been developed to measure nucleosome condensability and used to show that mononucleosomes contain sufficient information to condense into large-scale compartments without requiring any external factors.
Some cancer cells exhibit high loads of reactive iron in lysosomes, and this feature is exploited by using fentomycin-1, a newly developed small molecule, to induce ferroptosis.
