Associations between obesity-related gene expression in maternal and cord blood and newborn adiposity: findings from the Araraquara Cohort study.
Article in International journal of obesity (2005), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND/
objectivesGenes involved in the regulation of metabolism, adipose tissue deposition, inflammation, and the appetite-satiety axis may play an important role in fetal development, and possibly induce permanent metabolic changes and fat accumulation. In this study we investigated: (1) obesity-related gene expression in maternal and cord blood of overweight/obese and normal-weight pregnant women; (2) associations between obesity-related gene expression in maternal and cord blood; and (3) associations of gene expression in each of maternal and cord blood with newborn adiposity. SUBJECTS/
methodsTwenty-five overweight/obese and 32 normal-weight pregnant women were selected from the Araraquara Cohort Study according to their pre-pregnancy BMI. Maternal and cord blood gene expression of LEPR, STAT3, PPARG, TLR4, IL-6, IL-10, FTO, MC4R, TNF-α, and NFκB were investigated by relative real-time PCR quantification. The body composition of the newborns was assessed by air displacement plethysmography. Associations between maternal and cord blood gene expression and markers of newborn adiposity (weight, BMI, and fat mass%) were explored by linear regression models controlling for maternal age, pre-pregnancy BMI, maternal gestational weight gain, gestational age, and newborn sex.
resultsThere was higher TLR4, NFκB, and TNF-a expression, and lower IL-6 expression, in overweight/obese pregnant women and their respective newborns compared with normal-weight women and their newborns (p < 0.001). Maternal PPARG gene expression was associated with both weight and fat mass % of the newborns, and cord blood IL-10 expression was associated with BMI and fat mass %, controlling for confounders.
conclusionTo our knowledge, this is the first study to evaluate the relationship of maternal and cord blood gene expression with adiposity markers of the newborn. Our results provide evidence for the contribution of maternal and cord blood gene expression-particularly maternal PPARG and TLR4 expression, and cord blood IL-10 expression-to newborn weight, BMI, and fat mass %.
