Depletion of circulatory asparagine (Asn) by L-asparaginase (ASNase) has been used for clinical treatment of leukemia. Here this group develops core-shell structured cascade-responsive nanoparticles for sequential modulation of exogenous Asn supply and endogenous Asn production, thereby achieving the amino acid depletion therapy against solid tumors.
