ITGA11, a Prognostic Factor Associated with Immunity in Gastric Adenocarcinoma.
Article in International journal of general medicine, 2024. 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
Background: Stomach adenocarcinoma (STAD) presents a challenge given its advanced stage at diagnosis and poor prognosis. Integrin subunit alpha 11 (ITGA11) encodes alpha integrin and has been implicated in promoting tumorigenesis and development by participating in cell proliferation and invasion. However, the precise mechanism of ITGA11 in STAD remains unclear. Methods: The differences in ITGA11 expression levels between 375 gastric cancer samples and 32 paracancerous tissue samples from the Cancer Genome Atlas (TCGA) database were examined. The relationship between ITGA11 expression and clinical features and ITGA11 diagnostic and prognostic value were evaluated using the chi-square test and receiver operating characteristic (ROC) assay. Differentially expressed genes were identified based on ITGA11 expression. Subsequently, functional enrichment analyses were conducted using Gene Ontology, the Kyoto Encyclopedia of Genes and Genomes, and Gene Set Enrichment Analysis. Furthermore, immune infiltration and the expression of ITGA11-associated immune checkpoints in patients with tumors were assessed using CIBERSORT, single-sample gene set enrichment analysis, and the TIMER database. Drug sensitivity associated with ITGA11 expression was analyzed using the R oncoPredict package to guide treatment decisions. Finally, the difference in ITGA11 expression between cancer tissue and the adjacent tissues was validated using quantitative PCR (qPCR) and immunohistochemistry. Results: The gastric cancer tissue had significantly upregulated ITGA11 expression compared to paracancerous tissues. ITGA11 demonstrated robust diagnostic and prognostic value in gastric cancer (GC) and was an independent risk factor for adverse outcomes. The patients with STAD with elevated ITGA11 expression levels had heightened immune cell infiltration and increased immune checkpoint marker expression. Notably, patients with increased ITGA11 expression demonstrated reduced responsiveness to oxaliplatin and afatinib. Conclusion: The results indicated the pivotal role of ITGA11 in shaping the tumor immune microenvironment, ultimately establishing ITGA11 as an immune-related prognostic predictor within the intricate landscape of STAD.
