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

Phosphatidylinositol glycan anchor biosynthesis class U (PIGU), a crucial subunit of the glycosylphosphatidylinositol transamidase (GPI-T) complex, is an oncogene in hepatocellular carcinoma. However, its role in esophageal squamous cell carcinoma (ESCC) remains poorly understood. This study aims to clarify PIGU's role and mechanisms in ESCC by analyzing its expression across pan-cancer datasets, clinical relevance in TCGA-ESCA samples, and effects on cell behavior (migration, invasion, proliferation) and signaling pathways, validated via immunohistochemistry. To examine cell behavior, we used Transwell, colony-formation, CCK-8, and wound-healing assays to assess migration, invasion, proliferation, and wound healing.The epithelial-mesenchymal transition marker levels were measured using Western blot analysis, and the cell cycle and apoptosis were assessed using flow cytometry in conjunction with western blotting. Furthermore, we used western blotting to examine proteins implicated in the PI3K/AKT signaling pathway.To further confirm PIGU's role in ESCC progression, a subcutaneous xenograft mouse model was employed. Our findings suggest that PIGU is highly expressed in ESCC and is strongly associated with tumor growth, lymphatic metastasis and poor prognosis, and is an independent prognostic factor for ESCC patients.PIGU knockdown not only arrested the cell cycle and induced apoptosis, but also significantly reduced migration, invasion, and proliferation in ESCC cells. Additionally, vimentin and N-cadherin were downregulated when PIGU expression was silenced, although E-cadherin expression was simultaneously increased.Moreover, PIGU knockdown decreased the amount of phosphorylated Akt and PI3K. In vivo, PIGU knockdown inhibited ESCC cell proliferation and promoted apoptosis. These findings imply that targeting PIGU may represent a promising therapeutic approach, and that PIGU could potentially serve as both a diagnostic and prognostic biomarker for esophageal squamous cell carcinoma (ESCC).
