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

Ovarian cancer has a poor prognosis and advanced ovarian cancer lacks effective therapy. In this study, we seek to establish targeting therapy for ovarian cancer through tumor tissue-specific delivery of miRNA-29b to reexpress PTEN tumor-suppressor gene. A chimera (Chi-29b) was constructed to compose of a mucin 1 (MUC1) aptamer targeting tumor cell surface MUC1 protein and miR-29b inhibiting DNA methyltransferases' expression, subsequently reexpressing PTEN gene. The specificity and efficacy of the chimera delivery were analyzed in OVCAR-3 ovarian tumor cells, and the biological activities of the chimera were identified by the expression of its downstream molecules and cell apoptosis. We demonstrated that Chi-29b chimera can be specifically delivered into OVCAR-3 cells in a concentration-dependent manner. Dicer efficiently cleaved the Chi-29b chimera to release miR-29b. Chi-29b chimera downregulated Dnmt1, Dnmt3a, and Dnmt3b protein levels; induced hypomethylation in PTEN promoter; and upregulated PTEN mRNA and protein expression in OVCAR-3 cells. Importantly, Chi-29b chimera significantly induced apoptosis in OVCAR-3 cells. Our study indicated that Chi-29b chimera can effectively exert antitumor effect through specific delivery of miR-29b into OVCAR-3 tumor cells, subsequently reexpressing PTEN gene and inducing cell apoptosis.
