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

backgroundUncovering molecular pathogenesis and mechanisms of small cell lung cancer (SCLC) will contribute to SCLC therapy. Multiple studies demonstrated that miR-451a acts as an anti-tumor miRNA in non-small cell lung cancer. However, the mechanism of miR-451a in SCLC was ambiguous.

objectiveWe aimed to explore the function of miR-451a in SCLC and decipher the underlying mechanisms.

methodsTargetScan and dual-luciferase reporter assays were used to analyze the target genes of miR-451a. Cell counting kit-8 and colony formation assays were performed to assess the roles of miR-451a on cell growth. Gene set enrichment analysis (GSEA) was utilized to enrich biological pathways. Western blot was used to measure protein expression.

resultsMiR-451a expression was reduced dramatically in SCLC tissues and cell lines (NCI-H1688 and NCI-H446). Helicase, Lymphoid Specific (HELLS) was proved to be a target gene of miR-451a. In addition, cell proliferation assays in SCLC cells transfected with miR-451a mimic and/or HELLS revealed that miR-451a inhibited cell proliferation via targeting HELLS. Moreover, the roles of miR-451a/HELLS in expression of key proteins in mTOR and apoptosis signaling pathways suggested that miR-451a inactivated mTOR and activated apoptosis signaling pathway via directly silencing HELLS.

conclusionsOur study indicated that miR-451a hinders SCLC cell proliferation in vitro through regulating mTOR and apoptosis signaling pathways via silencing HELLS, suggesting that miR-451a could be a promising tumor suppressor in SCLC. And there is a potential for miR-451a to be a drug target and biomarker for SCLC.
