Synergistic Effect of Guanidinium and Tertiary Amine Groups on Boosting Gene Delivery.
Article in JACS Au, 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
The lack of safe and efficient delivery vectors remains a major bottleneck in nucleic acid therapeutics, limiting clinical translation. In this study, by incorporating the synergistic effects of guanidinium and tertiary amine functional groups, a new versatile branched poly-(β-amino ester) (PAE)-based delivery system was designed and developed, resulting in enhanced nucleic acid (DNA/mRNA) delivery. The synergistic interactions between these functional groups were systematically analyzed using 2D-NMR, AFM, TEM, and photophysical characterization. The results show that self-assembly occurs when polymers containing different functional groups are mixed, which changes the interactions between molecules and significantly affects the structure of the polyplex. This synergy was found to significantly enhance cellular uptake, contributing to improved transfection efficiency. Compared to the leading commercial reagents (Lipofectamine 3000, jetPEI, Xfect, and Lipofectamine MessengerMAX), the optimized polymeric vector formulations demonstrated superior transfection efficiency
