Abstract
Ferroptosis-related cancer therapy is limited by insufficient Fe2+ /Fe3+ redox pair and hydrogen peroxide (H2 O2 ) for producing lethal hydroxyl radicals (·OH). Although exogenous iron or ROS-producing drugs can enhance ferroptosis, exploiting endogenous iron (labile iron pool, LIP) stored in ferritin and promoting ROS generation may be safer. Herein, a metal/drug-free nanomedicine is developed for responsive LIP release and H2 O2 generation on the mitochondria membranes, amplifying hydroxyl radical production to enhance ferroptosis-mediated antitumor effects. A glutathione(GSH)/pH dual activatable fluorinated and cross-linked polyethyleneimine (PEI) with dialdehyde polyethylene glycol layer nanocomplex loaded with MTS-KR-SOD (Mitochondria-targeting-sequence-KillerRed-Superoxide Dismutase) and CRISPR/Cas9-CA IX (Carbonic anhydrase IX (CA IX)) plasmids (FP@MC) are developed for enhanced ferroptosis through endogenous iron de-hijacking and in situ ROS amplification. Two plasmids are constructed to knockdown CA IX and translate KillerRed-SOD recombinant protein specifically on mitochondria membranes, respectively. The CA IX knockdown acidifies the intracellular environment, leading the release of LIP from ferritin as a "flare" to initiate endogenous chemodynamic therapy. Meanwhile, MTS-KR-SOD generates H2 O2 when irradiated by a 590 nm laser to assist chemodynamic therapy, leading to ROS amplification for mitochondria damage and lipid peroxide accumulation. The combined therapeutic effects aggravate cancer ferroptosis and suppress tumor growth, providing a new paradigm for amplifying ROS and iron ions to promote ferroptosis-related cancer therapy.

Nat Commun 2023; 14:4429. [PMID: 37481653 PMCID: PMC10363139 DOI: 10.1038/s41467-023-40168-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 07/14/2023] [Indexed: 07/24/2023] Open
Abstract
Organic nonlinear optical materials have potential in applications such as lightings and bioimaging, but tend to have low photoluminescent quantum yields and are prone to lose the nonlinear optical activity. Herein, we demonstrate to weave large-area, flexible organic nonlinear optical membranes composed of 4-N,N-dimethylamino-4'-N'-methyl-stilbazolium tosylate@cyclodextrin host-guest supramolecular complex. These membranes exhibited a record high photoluminescence quantum yield of 73.5%, and could continuously emit orange luminescence even being heated at 300 °C, thus enabling the fabrication of thermotolerant light-emitting diodes. The nonlinear optical property of these membranes can be well-preserved even in polar environment. The supramolecular assemblies with multiphoton absorption characteristics were used for in vivo real-time imaging of Escherichia coli at 1000 nm excitation. These findings demonstrate to achieve scalable fabrication of organic nonlinear optical materials with high photoluminescence quantum yields, and good stability against thermal stress and polar environment for high-performance, durable optoelectronic devices and humanized multiphoton bio-probes.

Abstract
Although photodynamic therapy (PDT) is a promising antitumor strategy for tumor treatment, the short half-life and the limited diffusion distance of reactive oxygen species (ROS) greatly hamper its antitumor efficacy. Moreover, tumor cells develop antioxidative microenvironments to weaken the oxidative damage caused by PDT. Herein, a plasma membrane-targeted photooxidant (designated as SCPP) is prepared by the self-assembly of a chimeric peptide (Pal-K(PpIX)-R4) and sorafenib. Plasma membrane-targeted SCPP could enhance lipid peroxidation (LPO) through in situ PDT upon light irradiation. Moreover, sorafenib-mediated chemotherapy could block cystine/glutamate antiporter xCT (SLC7A11) to inhibit the syntheses of intracellular GSH and glutathione peroxidase 4 (GPX4), which would destroy the antioxidant defense system of tumors. As a consequence, SCPP achieves a highly efficient tumor inhibition through enhanced PDT and ferroptosis therapy. This study might provide guidance for multisynergistic tumor therapy with a sophisticated mechanism under unfavorable conditions.
