ERBB2 mutations promote recurrence and metastasis in non-muscle-invasive bladder cancer via HIF-1 phosphorylation: Insights from whole exome sequencing.

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
This study investigates the role of ERBB2 mutations in promoting recurrence and metastasis of non-muscle-invasive bladder cancer (NMIBC). Analysis of whole exome sequencing (WES) data from The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC) databases revealed a significant association between ERBB2 mutations and immune cell infiltration. To validate these findings, formalin-fixed, paraffin-embedded tumor tissues from patients with recurrent NMIBC were analyzed, with a focus on ERBB2 mutations. In addition, bladder cancer cell lines carrying wild type or mutant ERBB2 were established using clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein 9 (CRISPR/Cas9) technology. Functional experiments, including Western blotting, protein stability assays, and ubiquitination analyses, demonstrated that ERBB2 mutations promote hypoxia-inducible factor-1 (HIF-1) phosphorylation, leading to its stabilization and enhancing the proliferative, migratory, and invasive capacities of tumor cells. Furthermore, flow cytometry, 5-ethynyl-2'-deoxyuridine (EdU), Cell Counting Kit-8 (CCK-8), and Transwell assays confirmed the impact of these mutations on cellular behavior, while drug sensitivity assays indicated increased susceptibility of ERBB2-mutant cells to therapeutic agents.
