PYGO1 drives gastric cancer progression via the ITGB1/CD47 axis and is therapeutically targeted by pentagalloylglucose.

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
backgroundGastric cancer (GC) represents a significant therapeutic challenge due to its aggressive progression and limited treatment options, emphasizing the urgent need for novel therapeutic targets and strategies. Although PYGO1 functions as a Wnt co-transcriptional activator and chromatin effector, its role in cancer remains poorly characterized. This study aims to elucidate the role of PYGO1 in GC and uncover its regulatory mechanisms.
methodsBioinformatics analysis and immunohistochemistry were used to assess PYGO1 expression in GC tissues and its correlation with prognosis and immune cell infiltration. Cellular and animal models were applied to validate the role of PYGO1 in GC. RNA sequencing, flow cytometry, and immunofluorescence explored the underlying mechanisms. Co-immunoprecipitation coupled with mass spectrometry identified PYGO1-interacting proteins. Molecular docking and molecular dynamics simulations screened and evaluated potential PYGO1 inhibitors.
resultsPYGO1 was significantly overexpressed in GC tissues and positively correlated with M2 macrophage infiltration and adverse prognosis. Its knockdown significantly inhibited GC cell proliferation, migration, and invasion in vitro, and reduced tumor growth and metastasis in vivo. Mechanistically, PYGO1 knockdown impaired cell adhesion and disrupted cytoskeletal integrity in GC cells via downregulation of the ITGB1/CD47 axis, mediated by the interaction of PYGO1 with H3K4me
conclusionsOur study demonstrates the oncogenic role of PYGO1 in GC and identifies PGG as a potential inhibitor, highlighting the PYGO1/ITGB1/CD47 axis as a promising therapeutic target for GC.
