Exploring the key genes associated with breast cancer radiotherapy sensitivity based on the stromal-immune score and analysis of the WGCNA and ceRNA network.

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: Breast cancer is a highly malignant disease worldwide, but there are currently no sufficient molecular biomarkers to predict patient prognosis and guide radiotherapy. The tumor microenvironment (TME) is an important factor affecting tumor biological function, and changes in its composition are equally relevant to tumor progression and prognosis during radiotherapy. Methods: Here, we performed bioinformatic analyses using data obtained from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases to screen for molecular biomarkers related to the TME that may influence radiotherapy sensitivity. By combining immune scores and stromal scores and performing weighted coexpression network analysis (WGCNA), we identified key modules and hub genes to construct competing endogenous RNA (ceRNA) networks. Then, key pathways and genes were identified using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Furthermore, we explored the effect of THBS2 on the malignant phenotype of breast cancer through cellular experiments. Results: Genes in the PI3K-AKT pathway in the blue module were significantly enriched. Among the hub genes in the blue module, COL1A1, COL1A2, COL6A3, THBS2 and PDGFRB were negatively associated with RT sensitivity. Cellular experiments confirmed that knockdown of THBS2 inhibited the proliferation and invasion of breast cancer cells. Conclusion: These findings may provide new insights into the mechanisms of radiotherapy sensitivity in breast cancer patients, offering hope for the discovery of new therapeutic targets.
