Engineering a bi-functional nanoplatform containing FH peptide for preferential cardiac delivery to counteract doxorubicin-induced cardiotoxicity.
Article in Journal of translational medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDOX, an anthracycline antibiotic, is extensively utilized in the treatment of various solid tumors and hematological malignancies but is constrained by its cumulative cardiotoxicity. PDA has emerged as a promising drug delivery platform owing to its superior biocompatibility, pH-responsive drug release capability, and multifunctional surface properties.The FH peptide, which specifically targets Tenascin-C overexpressed in DOX-injured myocardium, offers a promising strategy to enhance cardiac-specific drug accumulation.
methodsIn vitro experiments were performed using primary neonatal mouse cardiomyocytes. Cardioprotective efficacy was evaluated in an acute DOX-induced myocardial injury mouse model, and antitumor activity was assessed in a 4T1 tumor-bearing mouse model.
resultsOur comprehensive analysis, including spectroscopic methods and physicochemical characterization, confirmed the successful integration of Dex and FH onto the PDA platform. Both in vitro and in vivo studies demonstrated that PDA-Dex/FH effectively treats DOX-induced cardiotoxicity, with FH incorporation enhancing cardiac targeting while preserving DOX's antitumor efficacy.
conclusionswe demonstrated that, under the experimental conditions of this study, PDA-Dex/FH not only markedly mitigates myocardial injury with enhanced cardiac accumulation but also retains the chemotherapeutic efficacy of doxorubicin, thereby.
