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

aimHepatic stellate cell (HSC) plays a pivotal role in liver fibrosis and is considered as the therapeutic target for the treatment of hepatic fibrosis. Tyrosine protein kinase plays an important role in the proliferation, activation of HSC. The purpose of the study is to investigate the effects of the tyrosine protein kinase inhibitor genistein on the proliferation and activation of cultured rat HSC.

methodsRat HSC were isolated from Wistar rats by in situ perfusion of collagenase and pronase and single-step density Nycodenz gradient. Culture-activated HSC were serum-starved and incubated with 10(-9) to 10(-5) mol/L concentration of genistein for 24, 48 or 72 h. In PDGF-induced HSC proliferation, HSC were stimulated with 10 microg.L(-1) PDGF-BB for 15 min, and then treated with genistein for the same time. Cell proliferation was measured by MTT assay and based on flow cytometric analysis of cell cycle. The a-smooth muscle actin (alpha-SMA) expression in HSC was studied with confocal laser microscopy and flow cytometry. c-fos, c-jun and cyclin D(1) expression in HSC was also detected by flow cytometry.

resultsGenistein inhibited basal and PDGF-induced proliferation of HSC at the concentration of 10(-8) to 10(-5)mol/L, and treatment with 10(-7) mol/L concentration of genistein for 48 h inhibited the HSC proliferation significantly (the inhibition rate was 70.3 %, P<0.05). Immunofluorescence detected by confocal laser microscopy and flow cytometry showed that treatment with 10(-7) mol/L genistein for 48 h suppressed the expression of alpha-SMA significantly in HSC (the specific fluorescence intensity were 60.2+/-21.5 vs 35.3+/-11.6 and 12.8+/-10.4 vs 9.54+/-6.39, respectively, both P<0.05). The intensity of c-fos, c-jun and cyclin D(1) expression of HSCs treated with 10(-7)mol/L genistein for 48 h was also significantly decreased compared with the controls.

conclusionGenistein influences proliferation of HSC, suppresses the expression of alpha-SMA in HSC and t inhibits the intensity of c-fos, c-jun and cyclin D(1) expression of HSCs. Genistein has therapeutic potential against liver fibrosis.
