A comprehensive analysis identifies and validates NPC1 as a potential biomarker for prognosis in HCC.

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
Niemann-Pick type C1 protein (NPC1), a key regulator of intracellular cholesterol transport and a transmembrane protein, has been implicated in carcinogenesis, particularly in hepatocellular carcinoma (HCC). Despite the noted association, the specific role of NPC1 in HCC remains underexplored. In this study, we conducted a comprehensive analysis of NPC1 expression across diverse gene expression databases to elucidate its prognostic significance and functional interactions. Utilizing LinkedOmics for co-expression network analysis and KEGG for functional enrichment, we identified a set of genes co-expressed with NPC1 and its associated biological pathways. Our findings demonstrate that NPC1 is frequently upregulated and amplified in HCC tumor tissues, with higher expression levels significantly associated with reduced overall survival (OS), progression-free survival (RFS), and disease-free survival (DFS). Functional enrichment analysis of the top 50 positively correlated genes with NPC1 highlighted significant enrichment in pathways related to organelle fission, nuclear division, chromosomal region spindle formation, and centrosome function, suggesting a role for NPC1 in DNA replication processes. These findings establish a correlation between NPC1 expression and HCC prognosis, laying the groundwork for future studies to explore the therapeutic potential of NPC1 inhibition in HCC.
