The influence of standardized Valeriana officinalis extract on the CYP3A1 gene expression by nuclear receptors in in vivo model.
Article in BioMed research international, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Valeriana officinalis is one of the most popular medicinal plants commonly used as a sedative and sleep aid. It is suggested that its pharmacologically active compounds derived from the root may modulate the CYP3A4 gene expression by activation of pregnane X receptor (PXR) or constitutive androstane receptor (CAR) and lead to pharmacokinetic herb-drug interactions. The aim of the study was to determine the influence of valerian on the expression level of CYP3A1 (homologue to human CYP3A4) as well as nuclear receptors PXR, CAR, RXR, GR, and HNF-4α. Male Wistar rats were given standardized valerian extract (300 mg/kg/day, p.o.) for 3 and 10 days. The expression in liver tissue was analyzed by using real-time PCR. Our result showed a decrease of CYP3A1 expression level by 35% (P = 0.248) and 37% (P < 0.001), respectively. Moreover, Valeriana exhibited statistically significant reduction in RXR (approximately 28%) only after 3-day treatment. We also demonstrated a decrease in the amount HNF-4α by 22% (P = 0.005) and 32% (P = 0.012), respectively. In case of CAR, the increase of expression level by 46% (P = 0.023) was noted. These findings suggest that Valeriana officinalis extract can decrease the CYP3A4 expression and therefore may lead to interactions with synthetic drugs metabolized by this enzyme.
