Current antitumor monotherapy has many limitations, highlighting the need for novel synergistic anticancer strategies. Ferroptosis is an iron-dependent form of nonapoptotic cell death that plays a pivotal regulatory role in tumorigenesis and treatment. Photodynamic therapy (PDT) causes irreversible chemical damage to target lesions and is widely used in antitumor therapy. However, PDT's effectiveness is usually hindered by several obstacles, such as hypoxia, excess glutathione (GSH), and tumor resistance. Ferroptosis improves the anticancer efficacy of PDT by increasing oxygen and reactive oxygen species (ROS) or reducing GSH levels, and PDT also enhances ferroptosis induction due to the ROS effect in the tumor microenvironment (TME). Strategies based on nanoparticles (NPs) can subtly exploit the potential synergy of ferroptosis and PDT. This review explores recent advances and current challenges in the landscape of the underlying mechanisms regulating ferroptosis and PDT, as well as nano delivery system-mediated synergistic anticancer activity. These include polymers, biomimetic materials, metal organic frameworks (MOFs), inorganics, and carrier-free NPs. Finally, we highlight future perspectives of this novel emerging paradigm in targeted cancer therapies.

Activatable multifunctional nanoparticles present considerable advantages in cancer treatment by integrating both diagnostic and therapeutic functionalities into a single platform. These nanoparticles can be precisely engineered to selectively target cancer cells, thereby reducing the risk of damage to healthy tissues. Once localized at the target site, they can be activated by external stimuli such as light, pH changes, or specific enzymes, enabling precise control over the release of therapeutic agents or the initiation of therapeutic effects.

Breast cancer is the most common type of cancer in women worldwide. A common approach to cancer treatment in clinical practice is to use a combination of drugs to enhance the anticancer activity of drugs while reducing their side effects. In this regard, we evaluated the effectiveness of combined treatment with gemcitabine (GCB) and arsenic (ATO) and how they affect the cell death pathway in cancer cells.

The alternative splicing (AS) of pre-mRNA is an important process in controlling the expression of human genes, which can enrich the diversity of the proteome and regulate gene function. On the contrary, aberrant splicing contributes significantly to numerous human diseases progression, including tumors, neurological diseases, metabolic diseases, infections, and immune diseases. The PUF60, a protein related to RNA splicing, plays critical functions in RNA splicing and gene transcription regulation.

Chemodynamic therapy (CDT) is a promising and potent therapeutic strategy for the treatment of cancer. We developed a DNA origami-based enzymatic cascade nanoreactor (DOECN) containing spatially well-organized Au nanoparticles and ferric oxide (FeO) nanoclusters for targeted delivery and inhibition of tumor cell growth. The DOECN can synergistically promote the generation of hydrogen peroxide (HO), consumption of glutathione, and creation of an acidic environment, thereby amplifying the Fenton-type reaction and producing abundant reactive oxygen species, such as hydroxyl radicals (•OH), for augmenting the CDT outcome.

The stimulator of interferon genes (STING) pathway exhibits great potential in remodeling the immunosuppressive tumor microenvironment and initiating antitumor immunity. However, how to effectively activate STING and avoid undesired toxicity after systemic administration remains challenging. Herein, platinum(IV)-backboned polymer prodrug-coated manganese oxide nanoparticles (DHP/MnONP) with pH/redox dual responsive properties are developed to precisely release cisplatin and Mn in the tumor microenvironment and synergistically amplify STING activation.
