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

CircRNAs are associated with adriamycin (ADM) resistance in triple‑negative breast cancer (TNBC), but the mechanism is unknown. Reverse transcription‑quantitative PCR was applied to quantify circular RNA (circRNA)_0044556, microRNA (miR)‑145 and NRAS proto‑oncogene, GTPase (NRAS) in TNBC tissues and cells with or without ADM treatment. Following ADM treatment, the effects of circRNA_0044556 on the viability, ADM resistance, apoptosis and migration of TNBC cells were investigated by cell function experiments (Cell Counting Kit‑8, flow cytometry and Transwell assays). The targeting relationship between circRNA_0044556 and miR‑145 was investigated via bioinformatics analysis, dual‑luciferase reporter assay and RNA immunoprecipitation. The effects of the circRNA_0044556/miR‑145 axis on the TNBC cells were revealed by rescue experiments. Correlations among circRNA_0044556, miR‑145 and NRAS were analyzed by Pearson's correlation test. CircRNA_0044556 was highly expressed in TNBC tissues and cells with or without ADM‑resistance. The overexpression of circRNA_0044556 promoted cell viability, ADM‑resistance and migration, while inhibiting the apoptosis by sponging miR‑145. Upregulation of miR‑145 reversed the effects of circRNA_0044556 on the TNBC cells. CircRNA_0044556 was negatively correlated with miR‑145 yet positively correlated with NRAS, the target gene of miR‑145, in addition to the discovery suggesting the negative regulatory effects of circRNA_0044556 on miR‑145. CircRNA_0044556 diminished the sensitivity of TNBC cells to ADM via the miR‑145/NRAS axis.
