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

Cytochrome P450 1B1 (CYP1B1) is involved in the metabolism of xenobiotic compounds and endogenous metabolites. Disruption of Cyp1b1 in mice results in suppression of high-fat diet (HFD)-induced obesity and an extensive change in hepatic energy regulation despite minimal constitutive expression of CYP1B1 in hepatocytes. Lack of CYP1B1 is correlated with altered lipid metabolism, especially lysophosphatidylcholines, contributing to protection against obesity. Ultraperformance liquid chromatography coupled to electrospray ionization quadrupole mass spectrometry (UPLC-ESI-QTOFMS)-based metabolomics revealed lysophosphatidylcholine 18:0 (LPC 18:0) as a biomarker positively related to HFD-induced obesity. The increased serum LPC 18:0 in wild-type mice is reduced in Cyp1b1-null mice on a HFD, which is reversed in CYP1B1-humanized mice. CYP1B1-humanized mice show higher diet-induced obesity compared with Cyp1b1-null mice, suggesting that human CYP1B1 shows a similar response to HFD as mouse Cyp1b1. In addition, hepatic stearoyl-CoA desaturase 1 (SCD1) expression was decreased in Cyp1b1-null mice, and the attenuated diet-induced obesity and lower serum LPC 18:0 in the Cyp1b1-null mice is elevated after SCD1 overexpression, suggesting that SCD1 is correlated with CYP1B1-induced obesity. These studies establish a biochemical link between cytochromes P450, lipids, and metabolic disorders and suggest that inhibition of CYP1B1 could be target for antiobesity drugs.
