Hepatic CYP3A expression and activity in low birth weight developing female rats.
Article in World journal of pediatrics : WJP, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe aimed to investigate the effects of low birth weight (LBW) on the hepatic expression of cytochrome P-450 3A (CYP3A) in developing female rats.
methodsPregnant rats were divided into two groups, a nourished group and an under-nourished group. The offspring of the nourished rats were defined as a normal weight, normal diet group (NN group). The offspring of the under-nourished rats were designated as a LBW, normal diet group (LN group). CYP3A mRNA expression, protein expression, protein localization and activity were determined.
resultsThe CYP3A1 mRNA expression levels of the LN group on days 3, 21, and 56 were significantly higher than those of the same age in the NN group (P≤0.01). The mRNA expression of CYP3A2 in the LN group on day 21 was higher than in rats of the same age in the NN group (P<0.01). The staining intensity and frequency of CYP3A1-positive hepatocytes were significantly lower on days 7 and 21 in the LN group than those of rats of the same age in the NN group (P<0.05). The staining intensity and frequency of CYP3A2-positive hepatocytes on days 14 and 21 were higher in the LN group than those on the same days in the NN group (P<0.05). The mean CYP3A activity of the LN group on day 3 was significantly higher than that of the NN group (P<0.001).
conclusionsWe found the effect of LBW on CYP3A activity was most prominent during the early days of life in rats. Investigators and clinicians should consider the effect of LBW on CYP3A in both pharmacokinetic study design and data interpretation, when prescribing drugs to LBW infants.
