1 · What the graph read from it

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.

2 · The registry

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

mRNA nanotherapeutics hold immense potential for treating a wide range of diseases, but their widespread clinical adoption is limited by current lipid nanoparticle (LNP) delivery platforms, which frequently face challenges such as limited biocompatibility, immunogenic response, insufficient mRNA delivery efficacy and stringent cold-chain requirements. In this study, we systematically screened a 20-member lipid mixture library by substituting ionizable lipids and sterol components to identify formulations with improved physicochemical and biological profiles. A lead candidate combining γ-oryzanol and DLin-KC2-DMA as LNPs, termed OryKL (or KO 12 LNPs), was identified, exhibiting spherical bleb-type and core-shell nanostructures (∼150 nm), high mRNA encapsulation, and significantly enhanced in vitro transfection efficiency compared to cholesterol-based controls. Intravenous administration of OryKL delivered Cre recombinase mRNA effectively across multiple organs in Ai9 reporter mice, resulting in distinct cell-level tropism, and no detectable toxicity or inflammation, as confirmed via qPCR, organ histology, hematological assessment and liver function tests. Additionally, OryKL retained transfection potency for at least 60 days in lyophilized form with 20% (w/v) sucrose, supporting ambient-stable storage. These findings establish γ-oryzanol as a promising sterol alternative and position OryKL as a biocompatible, effective, and storage-stable platform for next-generation mRNA therapeutics.
