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

Background: Triple-negative breast cancer (TNBC) is prone to immune escape, and the synergistic mechanism of kynurenine, AhR, and EMT remains unclear. Methods: TNBC cell lines and 4T1 orthotopic breast cancer mice were used for molecular, cellular, and in vivo intervention experiments. Results: Kynurenine induced EMT in an AhR-dependent way, promoted cell migration and invasion, upregulated CCL2/CCL22, and inhibited the function of CD8⁺GrB⁺ T cells. Snail overexpression promotes H3K4me3 histone modification at IDO1 and TDO2 promoters to epigenetically amplify tryptophan metabolic enzyme expression. The AhR antagonist CH-223191 blocked the loop and reversed tumor immune escape. Conclusion: This study demonstrates that the kynurenine-AhR-EMT positive feedback loop drives immune escape in TNBC, providing a rationale for combined targeted therapy.
