Gold Nanoparticles Enhance Radiosensitivity in Glioblastoma Cells.
Article in ACS omega, 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
backgroundGlioblastoma multiforme (GBM) is a highly aggressive primary brain tumor with a poor patient prognosis. Standard of care treatment includes maximal surgical resection, followed by radiotherapy and temozolomide administration. Despite this multimodal strategy, patients fail to achieve an effective response due to resistance to radio-treatment, allowing the tumor to recur. Therefore, there is a compelling need to discover new radiosensitizer approaches to overcome radioresistance and improve the response and survival of patients affected by glioblastoma. A novel approach is represented by nanoradiosensitizers, such as gold nanoparticles (AuNPs), able to enhance the effectiveness of radiotherapy.
methodsIn this study, we assessed the biological interaction of AuNPs with ionizing radiation (IR) in both immortalized and primary patient-derived glioblastoma cell lines.
resultswe observed that the combinatory effect of AuNPs with IR decreased cell viability and increased necrosis and apoptosis compared to cells treated only with IR or untreated cells. Additionally, our results showed an increase in the sensitization enhancement ratio (SER) of cells treated with AuNPs and IR. Furthermore, AuNPs showed a tumor-specific effect, since it did not seem to support the effects of radiation on the normal human astrocyte (NHA) cell line.
conclusionsOur results suggest that the use of AuNPrs can improve radiotherapy efficacy by increasing the radiosensitivity of the targeted cells.
