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

aimTo study the molecular mechanisms of retinoic acid (RA)on prolix-feration and expression of cyclin-dependent kinase inhibitors (CKI), i.e.p16, p21 and p27 in cultured rat hepatic stellate cells (HSC) stimulated with transforming growth factor beta 1 (TGF-beta1).

methodsHSC were isolated from healthy rat livers and cultured.After stimulated with 1mg/L TGF-beta1, subcultured HSC were treated with or without 1nmol/L RA. MTT assay, immunocytochemistry (ICC) for p16, p21, p27 and alpha-smooth muscle actin (alpha-SMA) protein, in situ hybridization (ISH) for retinoic acid receptor beta 2 (RAR-beta2) and p16, p21 and p27 mRNA and quantitative image analysis (partially) were performed.

resultsinhibited HSC proliferation (41.50%,P<0.05),decreased the protein level of alpha-SMA (55.09%, P<0.05), and induced HSC to express RAR-beta2 mRNA. In addition, RA increased the protein level of p16 (218.75%, P <0.05) and induced p21 protein expression; meanwhile, p27 was undetectable by ICC in both control and RA-treated HSC. However, RA had no influence on the mRNA levels of p16, p21 or p27 as determined by ISH.

conclusionUp-regulation of p16 and p21 on post-transcriptional level may contribute, in part, to RA inhibition of TGF-beta 1-initiated rat HSC activation in vitro.
