Lysosome-related molecular subtypes reveal prognostic signatures and immunotherapeutic implications in ovarian cancer.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Lysosomes are critical organelles that act as degradation centers and signaling hubs within cells, playing a significant role in various cellular processes and human diseases, including cancer. However, the extent to which they influence the heterogeneity and clinical outcomes of ovarian cancer (OC) remains inadequately understood. In this study, we used consensus clustering to identify two distinct lysosome-related clusters (LCs) in OC by analyzing the expression profiles of OC patients from The Cancer Genome Atlas (TCGA) database. Further analyses revealed the functional characteristics and immune landscapes of these subgroups, providing valuable insights into the tumor immune microenvironment (TIME) and tumor responses to immunotherapy. Additionally, we developed and validated a prognostic model based on differentially expressed genes (DEGs) between the two LCs, demonstrating its effectiveness in predicting patient prognosis, TIME characteristics, and immunotherapy potential in OC. A further investigation explored the relationship between lysosome-associated risk scores, IC50 values of standard antitumor agents, and the expression levels of prognostic genes. Finally, in vitro experiments showed that inhibiting CRHR1, a lysosome-associated prognostic gene, significantly reduced OC cell proliferation, invasion, and migration. In conclusion, our study establishes a novel lysosome-based classification and prognostic framework for OC, offering a practical tool to predict clinical outcomes and guide personalized immunotherapy strategies.
