Revolutionizing Heart Failure Therapy: Harnessing IVT mRNA and Fusion Protein Technology to Prolong rhBNP Half-Life.
Article in Pharmaceutical research, 2025. 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
purposeRecombinant human B-type natriuretic peptide (rhBNP) has been extensively proven to be an effective mean of heart failure (HF) therapy, but its clinical application is limited by its very short half-life. This study aims to combine in vitro transcribed mRNA (IVT mRNA) and fusion protein technology to develop a rhBNP-Fc mRNA drug with long half-life, high efficiency and few side effects to treat HF.
methodsThe rhBNP-Fc fusion mRNA with IgG4-Fc sequence was produced by IVT technology. rhBNP-Fc mRNA was transfected into HEK293T cells to examine the expression in vitro. rhBNP-Fc mRNA encapsulated in LNP was injected into normal mice to detect the translation efficiency, half-life and negative effects in vivo. Finally, it was injected into doxorubicin-induced HF mice to screen the cardiac protective effect.
resultsThe rhBNP-Fc fusion mRNA extended the half-life of rhBNP, showing sustained expression in cell line for at least one day. rhBNP-Fc mRNA translation showed dose-dependent levels, and was still detectable 5 d after injection in vivo. In the HF mouse model, a single administration of rhBNP-Fc mRNA-LNP improved cardiac function, including improving heart ejection and reducing HF biomarkers expression. Additionally, rhBNP-Fc mRNA-LNP treatment mitigated myocardial damage, normalized cardiomyocyte structure, and reduced the levels of pro-inflammatory cytokines.
conclusionThe rhBNP-Fc mRNA has the potential to serve as an alternative to traditional protein therapies, thereby reducing clinical dosages, injection frequencies, and treatment costs. Our findings offer new insights into the development and application of mRNA drugs, emphasizing their therapeutic potential in long-acting drugs.
