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 liver is the major organ responsible for lipid biosynthesis. Sterol regulatory element-binding proteins (SREBP) are major transcription factors that regulate the expression of genes regulating fatty acid and cholesterol biosynthesis. Here we show that elaidic acid upregulates hepatic de-novo fatty acid and cholesterol synthesis in HuH-7 cells. To define the molecular mechanism involved in this unique regulation on hepatic lipogenesis, luciferase reporter gene assays were performed in HEK293 cells to compare the regulation of sterol regulatory element (SRE) that is present in SREBP-target promoter by elaidic acid and oleic acid. The results show that elaidic acid potently induced SRE-luciferase activity, whereas oleic acid inhibited this activity. Furthermore, elaidic acid increased SREBP-1c mRNA, while oleic acid did not alter it. Oleic acid inhibited mature form of SREBP-1 protein level, while elaidic acid did not show inhibitory effects. In addition, elaidic acid was also found to increase several selected lipogenic genes that are involved in fatty acids and sterol synthesis. These data demonstrate a unique role of elaidic acid, the most abundant trans fatty acid, in modulating hepatic lipogenesis.
