A comparative investigation of catecholamines and glucocorticoids impact on glioblastoma invasive behavior via 2D and 3D cell culture.
Article in PloS one, 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
Prolonged or intense stress can contribute to the progression of various pathological conditions, including cancer. To explore how stress affects glioblastoma invasiveness, U87-MG cells with reduced proliferation were treated for four days with epinephrine or hydrocortisone (low/high doses) in 2D and 3D cultures. Migration, cell stiffness, and vimentin expression were assessed. In 2D scratch assays, the scratch closure rate was 46.4% in the control group. Treatment with epinephrine increased this rate up to 97.0%, while hydrocortisone reduced it to 13.3%. In 3D cultures, both treatments inhibited spheroid elongation; however, only epinephrine significantly enhanced cell dispersion. Compared to the control group (9.00 kPa), mean stiffness decreased down to 1.92 kPa with epinephrine and increased up to 26.28 kPa with hydrocortisone. Vimentin expression was significantly upregulated under all treatment conditions. Overall, epinephrine promotes glioblastoma invasiveness, while hydrocortisone limits migration. Although cell stiffness changes align with migratory results, vimentin is possibly involved in different mechanisms affected by these compounds.
