Mitochondria-Targeting Virus-Like Gold Nanoparticles Enhance Chemophototherapeutic Efficacy Against Pancreatic Cancer in a Xenograft Mouse Model.
Article in International journal of nanomedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Background: The dense and fibrotic nature of the pancreatic tumor microenvironment significantly contributes to tumor invasion and metastasis. This challenging environment acts as a formidable barrier, hindering effective drug penetration and delivery, which ultimately limits the efficacy of conventional cancer treatments. Gold nanoparticles (AuNPs) have emerged as promising nanocarriers to overcome the extracellular matrix barrier; however, their limited targeting precision, poor delivery efficiency, and insufficient photothermal conversion present challenges. Methods: We developed triphenyl phosphonium-functionalized high-branch gold nanoparticles, denoted as Dox@TPAu, to enhance drug delivery and targeting capabilities. The targeted penetration, biopharmaceutical and pharmacokinetic properties of Dox@TPAu were characterized, and the synergistic therapeutic effect was evaluated by the BxPC-3 xenograft tumor mouse model. Results: Dox@TPAu exhibits superior photothermal conversion efficiency (91.0%) alongside a high drug loading efficiency (26%) and effective photo-triggered drug-release potential. This Dox@TPAu drug delivery system adeptly accumulates at tumor sites due to its unique properties, enabling targeted localization within cancer cells and the mitochondria of stromal fibroblasts. This localization disrupts mitochondrial function and transfer-processes crucial for energy production, metabolism, and cell signaling within the tumor microenvironment. Pharmacokinetic analyses revealed an optimal spatiotemporal distribution of Dox@TPAu at the tumor site. This strategic accumulation enables precise disruption of both the physical barrier and cancer cells, enhancing treatment efficacy through near-infrared light-triggered local chemo-photothermal synergistic therapy. Conclusion: Our findings demonstrate that this innovative strategy effectively leverages the unique properties of mitochondria-targeting, virus-like AuNPs for precise and efficient stromal depletion, presenting a promising approach to enhance the efficacy of pancreatic cancer treatment.
