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

Acetaldehyde, the major active metabolite of alcohol, induces the activation of hepatic stellate cells (HSC), leading to over-production of alpha1(I) collagen and ultimately causing hepatic fibrosis. The underlying mechanisms of this process remain largely unknown. Transforming growth factor-beta1 (TGF-beta1) is a potent inducer of alpha1(I) collagen production. Accumulating evidence has shown a potential role for TGF-beta1 in alcohol-induced hepatic fibrogenesis. The aims of this study were to determine the effect of acetaldehyde on TGF-beta signalling, to elucidate the underlying mechanisms as well as to evaluate its role in expression of alpha1(I) collagen gene in cultured HSC. It was hypothesized that acetaldehyde activated TGF-beta signalling by inducing the expression of elements in the TGF-beta signal transduction pathway, which might contribute to alpha1(I) collagen gene expression in cultured HSC. Initial results revealed that acetaldehyde activated TGF-beta signalling in cultured HSC. Additional studies demonstrated that acetaldehyde stimulated the secretion and activation of latent TGF-beta1, and induced the expression of the type II TGF-beta receptor (Tbeta-RII). Further experiments found cis - and trans -activating elements responsible for Tbeta-RII gene expression induced by acetaldehyde. Activation of TGF-beta signalling by acetaldehyde contributed to alpha1(I) collagen gene expression in cultured HSC. In summary, this report demonstrated that acetaldehyde stimulated TGF-beta signalling by increasing the secretion and activation of latent TGF-beta1 as well as by inducing the expression of Tbeta-RII in cultured HSC. Results from this report provided a novel insight into mechanisms by which acetaldehyde stimulated the expression of alpha1(I) collagen in HSC and a better understanding of effects of alcohol (or acetaldehyde) on hepatic fibrogenesis.
