Identifying genes associated with Sorafenib resistance in hepatocellular carcinoma to develop risk model.
Article in Discover oncology, 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
backgroundHepatocellular carcinoma (HCC) poses a considerable global health challenge, notably due to the resistance to sorafenib therapy, which significantly impedes effective treatment strategies. This study aimed to identify potential resistance-associated genes and develop a robust prognostic model to predict patient outcomes.
methodsWe utilized transcriptomic data from the gene expression omnibus (GEO) database, focusing on sorafenib-resistant Huh7 and MHCC97H cell lines (GSE94550 and GSE176151), and integrated expression, mutation, and clinical data from the cancer genome atlas (TCGA) and international cancer genome consortium (ICGC) databases. Single-cell RNA sequencing data (GSE149614) were processed with the Seurat and Harmony R packages for quality control and integration. Differential gene expression analysis, consensus clustering, and principal component analysis were performed to identify significant genes and stratify patients based on prognostic outcomes.
resultsThe analysis revealed 305 potential resistance-associated genes, with a seven-gene (ANAPC13, NCAPD2, KIF2C, CDK5RAP2, MANBA, PPAT, and LPCAT1) risk model demonstrating significant prognostic capability, indicated by area under curve values of 0.824, 0.746, and 0.717 for 1, 3, and 5-year survival predictions, respectively. Notably, immune cell infiltration analyses highlighted significant correlations between risk scores and specific immune cell types, suggesting potential therapeutic targets. Drug sensitivity analysis further identified various compounds with lower IC50 values in high-risk groups. To facilitate clinical application, a nomogram plot was designed.
conclusionThis study provides a comprehensive framework for understanding sorafenib resistance in HCC, alongside a validated prognostic model that holds potential for clinical application.
