Functional clustering analysis identifies specific subtypes of aldehyde dehydrogenase associated with glioma immunity.

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
backgroundAs a novel cancer stem cell marker, the biological functions of aldehyde dehydrogenases (ALDH enzymes) are a hot topic in current cancer research. However, there is a lack of systematic understanding of ALDH enzymes, which has hindered the translation of targeted therapies from bench work into the clinic.
methodsBased on transcriptome data from 999 glioma patients, functional clustering analysis was performed to reveal the functional phenotypes of ALDH isoforms. Subsequently, ALDH subgroups closely related to gliomas were identified by Cox survival analysis. Finally, gene set variation analysis (GSVA) and Pearson correlation analysis were used to explore the biological functions of ALDH enzymes.
resultsOur study found that ALDH enzymes could be classified into 5 subgroups, among which 3 groups were closely related to malignant progression and the prognosis of gliomas. We found that ALDH enzymes were closely related to gene mutations, which were most likely caused by changes in DNA repair functions. Further studies revealed that ALDH enzymes affect tumor immune functions, especially the expression of immune checkpoints. The effectiveness of immune checkpoint inhibitors in treating glioma might be improved by altering the expression of ALDH enzymes in specific subgroups.
conclusionsThis study comprehensively revealed the biological functions of ALDH enzymes in glioma and provided details about the potential clinical application of targeted therapy for ALDH enzymes.
