Placental expression of GLUT-1, GLUT-3, and GLUT-4 mRNA and transcriptome profiling in pregnant women with diabetes.

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
AIMS/
introductionPlacental glucose transport is regulated by glucose transporter proteins (GLUTs). The study aimed to examine placental expression of GLUT-1, GLUT-3, and GLUT-4 mRNA in patients with type 1 diabetes, early gestational diabetes (eGDM), and healthy controls, and to investigate correlations between GLUTs expression and clinical parameters. Additionally, we compared placental transcriptome profiles in recruited subgroups. MATERIALS AND
methodsWe recruited 59 pregnant women: 23 with type 1 diabetes, 17 with eGDM, and 19 controls. Patients with diabetes attended follow-up visits at each trimester. Transcriptome studies were performed in 4 patients per subgroup.
resultsThe mean age was similar across all subgroups. eGDM patients had significantly higher BMI and were predominantly obese. We observed a significant 2-fold (P = 0.009) decrease in placental GLUT-3 mRNA expression in the type 1 diabetes and eGDM groups. GLUT-4 mRNA expression was significantly lower in the eGDM group compared to type 1 diabetes (3-fold) and controls (6-fold) (P = 0.007). There was a significant negative correlation between GLUT-3 (R = -0.29) and GLUT-4 (R = -0.27) mRNA expression and neonatal birth weight. GLUT-4 expression was negatively correlated with 1st trimester HbA1c (R = -0.72) and OGTT 120' (R = -0.82) results in eGDM patients, and 3rd trimester glycemic variability (R = -0.49) in type 1 diabetes. Microarray analysis revealed significant transcriptomic changes, with 45 down-regulated and 365 up-regulated genes in type 1 diabetes, and 21 significant changes in eGDM.
conclusionsPlacental samples from patients with diabetes exhibit changes in GLUTs expression, which correlates with neonatal growth and several glycemic parameters. Additionally, multiple changes in transcriptomic profiles are observed in hyperglycemic patients.
