PRR11 Promotes Bladder Cancer Growth and Metastasis by Facilitating G1/S Progression and Epithelial-Mesenchymal Transition.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAlthough Proline-rich Protein 11 (PRR11) abnormalities are closely associated with carcinogenesis, the precise mechanism of bladder cancer remains unclear. Here, we sought to elucidate the molecular mechanisms of PRR11 in bladder cancer.
methodsWe performed differential expression analysis of PRR11 from the TCGA and GEO databases, followed by validation with clinical samples. Survival analysis was employed to assess the correlation between PRR11 and patient prognosis. The effects of PRR11 on bladder cancer cells were examined through both in vitro and in vivo experiments. Additionally, Gene Set Enrichment Analysis (GSEA) was used to predict the downstream pathways associated with PRR11, which were further validated through subsequent experiments.
resultsPRR11 is upregulated in bladder cancer and could lead to poor prognosis. In vitro, PRR11 promoted tumor cell proliferation; in vivo, it promoted subcutaneous tumor growth. PRR11 knockdown inhibited its oncogenic function. On the molecular level, PRR11 promotes tumor metastasis by inducing Epithelial-mesenchymal Transition (EMT). GSEA suggests that PRR11 is strongly linked to the cell cycle, and silencing of PRR11 can achieve anti-tumor effects by inhibiting CCNE and blocking the G1/S phase transition.
conclusionsOur study demonstrates that silencing PRR11 can arrest the malignant progression of bladder cancer by inhibiting EMT and blocking the G1/S transition. Targeting PRR11 may provide new insights for targeting cell cycle therapy.
