scRNA-Seq Analysis Revealed CAFs Regulating HCC Cells via PTN Signaling.
Article in Journal of hepatocellular carcinoma, 2024. 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
Background: Cancer-associated fibroblasts (CAFs) play a pivotal role in shaping the microenvironment of hepatocellular carcinoma (HCC). However, the mechanisms through which CAFs influence the progression of HCC remain incompletely understood. Methods: Single-cell RNA sequencing datasets (GSE158723 and GSE112271) were retrieved from the Gene Expression Omnibus (GEO) database at the National Center for Biotechnology Information (NCBI) and analyzed using R software. Our analysis suggested that CAFs may promote liver cancer cell development, possibly through the interaction of pleiotrophin (PTN) and syndecan-2 (SDC2). Clinical samples from HCC patients were collected and processed into frozen sections and single-cell suspensions for Masson staining, immunofluorescence staining, and flow cytometry. Additionally, Huh7 liver cancer cells and LO2 normal liver cells were cultured and subjected to immunofluorescence assays using cell slides. Results: The proportion of CAFs in cancerous tissues was higher than in adjacent non-cancerous tissues, and pleiotrophin (PTN) expression was elevated in cancer tissues compared to adjacent tissues. These findings aligned with the results of the single-cell RNA sequencing (scRNA-seq) analysis. Furthermore, SDC2 expression was significantly upregulated in Huh7 liver cancer cells compared to LO2 normal liver cells. Discussion: This study suggests that CAFs may contribute to HCC progression via the PTN/SDC2 signaling pathway. Our findings provide deeper insights into the interactions between CAFs and HCC cells within the tumor microenvironment (TME).
