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

Background and Aims: Transmembrane 6 superfamily member 2 (TM6SF2) p.Glu167Lys (E167K) is associated with hepatic steatosis and male-predominant type 2 diabetes (T2D) presumably due to defective secretion of very low density lipoprotein (VLDL) particles. The causal relationship between secreted VLDL density and insulin sensitivity in the context of the E167K variant remains unclear. Methods: E167K-carrying induced pluripotent stem cells were generated using a genome-editing method. Guided by targeted phospholipidomic analysis, we established an improved protocol to derive hepatocyte-like cells (HLCs) from induced pluripotent stem cells with significantly improved VLDL secretory profiles after linoleic acid, arachidonic acid and Liver X receptor agonist exposure. Furthermore, the E167K-defined steatosis and metabolic phenotype of HLCs treated with or without dihydrotestosterone were analyzed. In public database, we stratified male subjects by testosterone level and analyzed the impact of TM6SF2 on the incidence of hepatic steatosis and T2D. Results: E167K hepatocytes showed defective VLDL secretion and an exacerbated lipid accumulation phenotype, accompanied by a decrease in arachidonic acid-containing phosphatidylcholine. Furthermore, dihydrotestosterone supplementation worsened the steatotic phenotype of E167K HLCs without altering insulin sensitivity. In the clinical data, E167K-defined hepatic steatosis was testosterone-dosage dependent unlike the other genetic variant, while T2D was not. Conclusion: We report an improved human hepatocyte differentiation model to investigate metabolic dysfunction with functional VLDL secretory profiles influenced by TM6SF2 gene variant.
