Molecular and ultrastructure study of endoplasmic reticulum stress in hepatic steatosis: role of hepatocyte nuclear factor 4α and inflammatory mediators.

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.
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
Endoplasmic reticulum (ER) stress could participate in high-fat diet (HFD)-induced hepatic steatosis. The current study aims to investigate the role of ER stress as well as inflammation as possible pathophysiologic mechanisms of HFD-induced hepatic steatosis at ultrastructure and molecular levels. Fifteen control rats on ordinary diet and 30 HFD-fed rats were enrolled in the study. Histological and EM examinations of rats' liver were carried out. Molecular study of TNF-α, CRP, and HNF4α by RT qPCR as well as biochemical investigation of liver function and lipids profile were done. Hepatic steatosis was induced with lipid droplets accumulation at histological level and mega-mitochondria with reduced ER-mitochondrial distance at EM level. Increased gene expression of TNF-α and CRP was significantly correlated with the reduced HNF4α expression and with other ER stress markers. In conclusion, endoplasmic reticulum stress, confirmed at ultrastructure level, plays an important role in pathogenesis of HFD-induced hepatic steatosis. HNF4α downregulation as well as increased expression of hs-CRP and TNF-α enforce the concept of interplay between ER stress, hepatic subclinical inflammation, and disturbed gene expression regulation in the pathogenesis of HFD-induced hepatic steatosis.
