Enhancing the Pharmacokinetics of Aptamers: Targeting AXL In Vivo Using a Bottlebrush Polymer-Conjugated Aptamer.
Article in Advanced healthcare materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 overexpression of receptor tyrosine kinase AXL receptor tyrosine kinase (AXL) is linked to acquired drug resistance in cancer treatments. Aptamers, acting as antibody surrogates, have been envisioned as potential inhibitors for AXL. However, aptamers face difficult pharmacological challenges including rapid degradation and clearance. Herein, a phosphodiester-backboned bottlebrush polymer is reported as a carrier for conjugated aptamers. Termed polymer-augmented conjugates of DNA (pacDNA), the conjugate improves aptamer specificity in vivo, prolongs blood retention, and enhances overall aptamer bioactivity. Treatment with pacDNA in AXL-overexpressing cell lines significantly inhibits AXL phosphorylation, resulting in reduced cancer cell migration and invasion. In a non-small cell lung cancer xenograft model (NCI-H1299), pacDNA treatment leads to single-agent reduction in tumor growth. These results highlight the potential of bottlebrush polymers in the field of aptamer therapeutics.
