1 · What the graph read from it

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.

2 · The registry

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

The PEST-containing nuclear protein (PCNP) has been reported to play paradoxical roles in tumorigenesis. While PCNP functions as a tumor suppressor in neuroblastoma and lung adenocarcinoma, it has been identified as a tumor promoter in ovarian cancer. However, the underlying mechanisms driving these contrasting effects remain unclear. Gene Expression Profiling Interactive Analysis (GEPIA) was employed to analyze relevance of PCNP expression with prognosis in HCC. To evaluate the role of PCNP in hepatocellular carcinoma (HCC), we analyzed the expression of PCNP in 87 HCC tissues and 80 adjacent normal tissues. Correlation between PCNP and ubiquitin-like with PHD and ring finger domains 2 (UHRF2) was transcriptionally detected, and then their effects on malignant behaviors, including proliferation, invasion, tumor formation in vitro and in vivo were evaluated. According to tissues array results, it is found that PCNP was significantly upregulated in HCC tissues, which was further confirmed in HCC cell lines by western blotting. Importantly, both the cytoplasmic and nuclear PCNP fractions were correlated with pathological grade, T staging, clinical staging and recurrence, and patients with a high level of PCNP had lower overall survival and disease-free survival and a higher recurrence rate than those with a low PCNP level, indicating that PCNP might be an independent prognostic factor for HCC patients. Functional investigations revealed that PCNP knockdown inhibited malignant behaviors, including proliferation, invasion, colony formation and tumor formation, in vitro and in vivo. Pearson correlation analysis indicated a positive association between PCNP and UHRF2, with evidence that PCNP transcriptionally upregulates UHRF2. Furthermore, ectopic overexpression of PCNP activated the ErbB3/Ras/Raf1 signaling pathway through upregulation of UHRF2. Our findings suggest that PCNP promotes HCC progression by activating the ErbB3/Ras/Raf signaling pathway through upregulation of UHRF2. Consequently, PCNP holds potential as both a diagnostic biomarker and a therapeutic target for hepatocellular carcinoma.
