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

objectiveIncreased fatty acid and triglyceride synthesis in liver, majorly modulated by Sterol Regulator Elementing Binding Protein 1c (SREBP1c), is one of the main features of non-alcoholic fatty liver disease (NAFLD). In the present study, we aimed to identify the relation between SREBP1c and autophagy mediated lipid droplet (LD) catabolism in oleic acid (OA) induced lipid accumulation.

methodsIncreased LD formation and SREBP1c induction were identified in hepatocytes (AML12 cells) following the OA administration. SREBP1c level was reduced through siRNA against SREBP1c. The amount and the size of LDs were determined by BODIPY, while protein and mRNA expressions were identified by immunoblotting and qRT-PCR, respectively. LD-lysosome colocalization was determined with immunofluorescence.

resultsIncreased LD formation and SREBP1c levels were determined at 0.06 mM OA concentration. SREBP1c silencing reduced the number of LDs, while increasing mRNA levels of PPARα. On the other hand, SREBP1c silencing in non-OA and OA treated cells enhanced autophagy mediated LD catabolism.

conclusionOur results implicate the effect of SREBP1c deficiency in modulating PPARα signaling and autophagy mediated LD catabolism against OA induced lipid accumulation.
