Highly Adaptable Dendrimer Gel Nanoparticles with Dual Targeting of uPAR and Ribonucleotide Reductase R2 for Better Retention and Improved Therapeutic Outcomes in Triple-Negative Breast Cancer.
Article in ACS applied materials & interfaces, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Triple-negative breast cancer (TNBC) accounts for approximately 15% of breast cancers and lacks estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2), rendering it unresponsive to hormonal or anti-HER2 therapies. Due to its poor prognosis and limited treatment options, there is an urgent need for targeted therapies. In this study, we developed highly adaptable polyamidoamine (PAMAM) dendrimer-based gel nanoparticles with dual-targeting capabilities against urokinase-type plasminogen activator receptor (uPAR) and ribonucleotide reductase R2 (R2). These nanoparticles were designed to target both TNBC cells and cancer-associated stromal cells by leveraging uPA-uPAR interactions and delivering the antisense oligonucleotide GTI-2040 (GTI) against R2. The resulting dual-functional dendrimer gel nanoparticles, GDP-uPA/GTI, demonstrated good biocompatibility, with an average size of ∼16.45 nm. GDP-uPA/GTI enhanced GTI delivery by 3.4-fold in TNBC cells (MDA-MB-231) and by 4.8-fold in stromal cells (HCC2218) compared to GTI alone. It reduced R2 expression by 83.1% and induced ∼30% TNBC cell death. In a TNBC xenograft model, GDP-uPA/GTI significantly inhibited tumor growth by 50.5%. These findings highlight the unique design of the dual-functional dendrimer gel nanoparticles and their dual-targeting efficacy, demonstrating their potential as a promising therapeutic strategy for TNBC.
