Metal-organic framework nanoparticles activate cGAS-STING pathway to improve radiotherapy sensitivity.
Article in Journal of nanobiotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Tumor immunotherapy aims to harness the immune system to identify and eliminate cancer cells. However, its full potential is hindered by the immunosuppressive nature of tumors. Radiotherapy remains a key treatment modality for local tumor control and immunomodulation within the tumor microenvironment. Yet, the efficacy of radiotherapy is often limited by tumor radiosensitivity, and traditional radiosensitizers have shown limited effectiveness in hepatocellular carcinoma (HCC). To address these challenges, we developed a novel multifunctional nanoparticle system, ZIF-8@MnCO@DOX (ZMD), designed to enhance drug delivery to tumor tissues. In the tumor microenvironment, Zn²⁺ and Mn²⁺ ions released from ZMD participate in a Fenton-like reaction, generating reactive oxygen species (ROS) that promote tumor cell death and improve radiosensitivity. Additionally, the release of doxorubicin (DOX)-an anthracycline chemotherapeutic agent-induces DNA damage and apoptosis in cancer cells. The combined action of metal ions and double-stranded DNA (dsDNA) from damaged tumor cells synergistically activates the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, thereby initiating a robust anti-tumor immune response. Both in vitro and in vivo experiments demonstrated that ZMD effectively activates the cGAS-STING pathway, promotes anti-tumor immune responses, and exerts a potent tumor-killing effect in combination with radiotherapy, leading to regression of both primary tumors and distant metastases. Our work provides a straightforward, safe, and effective strategy for combining immunotherapy with radiotherapy to treat advanced cancer.
