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

Antimicrobial peptides (AMPs), an important part of the innate immune system, are crucial for defense against invading microorganisms. Whereas AMPs have been extensively studied in adult skin, little is known about the impact of AMPs in the developing human skin. We therefore compared the expression and regulation of AMPs in fetal, neonatal, and adult keratinocytes (KCs) in vitro. The constitutive expression of human β-defensin-2 (HBD-2), HBD-3, S100 protein family members, and cathelicidin was significantly higher in KCs from fetal skin than in KCs from postnatal skin. The capacity to further increase AMP production was comparable between prenatal and postnatal KCs. Analysis of skin equivalents (SEs) revealed a strong constitutive expression of S100 proteins in fetal but not in neonatal and adult SEs. The elevated AMP levels correlated with reduced H3K27me3 (tri-methyl-lysine 27 on histone H3) levels and increased expression of the histone demethylase JMJD3. Knockdown of JMJD3 in fetal KCs elevated H3K27me3 levels and significantly downregulated the expression of HBD-3, S100A7, S100A8, S100A9, and cathelicidin. Our data indicate a crucial contribution of histone modifications in the regulation of AMP expression in the skin during ontogeny. The elevated AMP expression in prenatal skin might represent an essential defense strategy of the unborn.
