Examining the effect of lipid nanoparticle elasticity on endocytosis and mRNA delivery to cancer cells.
Article in Med-X, 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
Lipid nanoparticles (LNPs) have emerged as modular and potent vehicles for nucleic acid delivery, offering a potentially promising new strategy for cancer therapy. This study investigates how LNP elasticity, modulated through variations in sterol lipid structure and sterol lipid molar ratio, affects LNP endocytosis and mRNA transfection in liver (HepG2), ovarian (OVCAR8), and lung (H1299) cancer cell lines. All LNP formulations were characterized for size, polydispersity index, and mRNA encapsulation efficiency and subsequently assessed for mRNA transfection in HepG2, OVCAR8, and H1299 cancer cells. In vitro screening showed that LNP elasticity influences mRNA transfection across all three cell types. Specifically, LNPs of intermediate stiffness enhanced mRNA transfection in HepG2 and OVCAR8 cells whereas LNPs with low stiffness improved mRNA transfection in H1299 cells. Mechanistic endocytosis studies showed that clathrin-mediated and lipid raft-mediated endocytosis pathways contribute to LNP uptake in all three cell lines. These findings highlight the promise of tuning LNP elasticity to enhance mRNA delivery to cancer cells and potentially improve the therapeutic efficacy of LNPs for cancer therapy applications.
