The GD3 ganglioside promotes cell growth, plasticity and chemotherapy resistance of human glioblastoma cancer stem cells.
Article in Cancer cell international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundGlioblastoma is the most aggressive primary brain tumour with no curative treatment and inevitable relapse. Therapeutic resistance is, at least, related to the presence of cancer stem-like cells in these tumours. Here, we aimed to demonstrate that the GD3 ganglioside was a relevant marker and actionable target for glioblastoma cancer stem-like cells.
methodsTo this end, we used commercial glioblastoma cell lines, human glioblastoma samples, organotypic culture and xenografted mouse models to study GD3 antigen expression and consequences of its downregulation through a shRNA strategy targeting the ST8SIA1 mRNA which encodes the key enzyme for GD3 synthesis. We performed mono-dimensional Thin Layer Chromatography to analyse ganglioside composition of the glioblastoma samples and RNA-seq analyses to reveal oncogenic pathways and more specifically transcripts affected by ST8SIA1 silencing. Besides, we evaluated GD3 role in stemness of glioblastoma cancer cell, phenotype, microenvironment interaction, and invasion abilities.
resultsWe showed that GD3 is the main ganglioside in glioblastoma and that patient-derived cancer stem-like cell lines strongly expressed GD3. This GD3 + population decreased significantly after cell differentiation. GD3
conclusionsTaken together, our results suggest that GD3 ganglioside is essential for glioblastoma cancer stem-like cell properties, opening promising targeted therapeutic development.
