1 · What the graph read from it

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.

2 · The registry

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

Glioblastoma (GBM) is a highly aggressive and lethal form of brain tumor that resists immunotherapy. Here we show that neuropeptide galanin (GAL) drives immunosuppression and immunotherapy resistance in GBM. Mechanistically, GBM cell-secreted GAL interacts with its receptor GALR3 on monocytic myeloid-derived suppressor cells (mMDSCs), triggering USP51-mediated deubiquitination of estrogen receptor-α, thereby engaging membrane-bound O-acyltransferase domain-containing 1 signaling. This signaling cascade, in turn, promotes the infiltration of immunosuppressive mMDSCs and confers ferroptosis resistance to them in the tumor microenvironment. Targeting mMDSCs through GALR3 inhibition and ferroptosis induction impairs tumor progression and activates antitumor immunity in GBM mouse models. Remarkably, combining this approach with anti-PD1 therapy achieves durable and complete tumor regression in approximately 60% of tumor-bearing mice. Our study elucidates the molecular mechanism underlying GBM immunosuppression and highlights a promising therapeutic strategy to enhance GBM response to immunotherapy.
