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

backgroundRetinoic acid (RA) regulates key biological processes, including differentiation, apoptosis and cell survival. RA mediates induction of 17 beta-hydroxysteroid dehydrogenase type 2 mRNA, catalyzing the conversion of estradiol to estrone, in endometrium but not endometriosis because of a defect in endometriotic stromal cells. This defect may involve both the uptake and metabolism of RA. In this study, we analyze the expression of genes involved in RA signaling in normal endometrium and endometriosis.

methodsTissue and stromal cells from ovarian endometriomas and eutopic endometrium from disease-free women were collected. Real-time reverse transcription-polymerase chain reaction was used to measure mRNA levels. Western blotting was used to evaluate protein expression.

resultsWe found that endometriotic tissue and stromal cells demonstrated significantly decreased mRNA expression of the major genes involved in RA signaling, including STRA6, CRBP1, ALDH1A2, CRABP2 and FABP5. We found increased levels of CYP26B1, responsible for RA metabolism. Nuclear extracts showed that RARα, RXRα and PPARβ/δ were underexpressed in both tissues and stromal cells from endometriotic tissue. Differences in protein levels were confirmed by western blotting.

conclusionsEndometriosis is characterized by a gene expression pattern suggesting a decrease in uptake and metabolism of RA. Because RA is integral in regulating key biological processes involved in cell survival, this alteration could partially explain the resistance to apoptosis found in endometriosis.
