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

The aging liver is affected by several disorders, including steatosis, that can lead to a decline of liver functions. Here, we present evidence that the cdk4-C/EBPα-p300 axis is a critical regulator of age-associated disorders, including steatosis. We found that patients with non-alcoholic fatty liver disease (NAFLD) have increased levels of cdk4 and that cdk4-resistant C/EBPα-S193A mice do not develop hepatic steatosis with advancing age. Underlying mechanisms include a block in C/EBPα activation and subsequent failure in activation of enzymes involved in the development of NAFLD. Inhibition of cdk4 in aged wild-type (WT) mice by a specific cdk4 inhibitor, PD-0332991, reduces C/EBPα-p300 complexes and eliminates hepatic steatosis. Moreover, the inhibition of cdk4 in aged mice reverses many age-related disorders. Mechanisms of correction include elimination of cellular senescence and alterations in the chromatin structure of hepatocytes. Thus, the inhibition of cdk4 might be considered as a therapeutic approach to correct age-associated liver disorders.
