Exosomal miRNA-720 as a potential diagnostic and prognostic biomarker for hepatocellular carcinoma.

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/
aimsCirculating exosomal microRNAs (miRNAs) can serve as diagnostic and prognostic biomarkers for cancer. This study aimed to identify specific miRNAs in serum exosomes of patients with hepatocellular carcinoma (HCC) and validate their biological functions as novel diagnostic and predictive biomarkers.
methodsSerum exosomal miRNAs in patients with HCC (n = 241) and without HCC (n = 45) were measured by qRT-PCR. The role of exosomal miRNAs in HCC was investigated through in vitro tests and verified in a clinical cohort of patients.
resultsIn vitro, we observed delivery of exosomal miRNA-720 (miR-720) to recipient cells. Exosome-mediated miR-720 promoted proliferation and inhibited apoptosis of recipient HCC cells. Exosomal miR-720 inhibited tumor suppressor StarD13 expression in recipient cells. Additionally, exosomal miR-720 promoted stemness in recipient cells by increasing protein expression of stemness-associated markers such as OCT4 and c-MYC. In our cohort, serum exosomal miR-720 was significantly upregulated in HCC patients than in non-HCC patients, showing an excellent diagnostic performance for HCC. Particularly, exosomal miR-720 exhibited superior performance in diagnosing small HCC (< 2 cm) compared to AFP or DCP. Exosomal miR-720 levels positively correlated with advancing tumor stage and size. Patients with high expression of exosomal miR-720 had significantly shorter time to progression than those with low expression of exosomal miR-720 during transarterial chemoembolization (TACE).
conclusionOur results demonstrate that exosomal miR-720 plays an oncogenic role in HCC by targeting StarD13. Circulating exosomal miR-720 could be used as a novel diagnostic and therapeutic biomarker and serve as a guide for selecting treatment options including TACE for HCC.
