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

The pathogenesis of angiostrongyliasis, resulting from the third-stage and the fourth-stage Angiostrongylus cantonensis larvae invasion of the human central nervous system, remains elusive. MicroRNAs are important regulators of gene expression and involved in many biological processes. The aim of this study was to determine and characterize miRNAs of third (L3) and fourth (L4) larvae of A. cantonensis by Solex deep sequencing. A total of 629 conserved miRNAs (526 and 376 miRNAs in L3 and L4 larvae of A. cantonensis, respectively) and three novel candidate miRNA from L3 and L4 larva of A. cantonensis were identified with bioinformatic analysis. There were 163 miRNAs upregulated and 54 miRNAs downregulated (fold changes ≥5.0) in the L4 of A. cantonensis compared with that of L3 of A. cantonensis. Interestingly, Gene Ontology "biological process" classifications revealed that 26 miRNAs of significantly differential expression are associated with the immune system, which implies that these miRNAs might participate in the pathogenesis of angiostrongyliasis by regulating genes involved in immune response pathways. Furthermore, the differential expression patterns of 26 conserved miRNAs between L3 and L4 of A. cantonensis were verified. The results of real-time PCR and Northern blot showed that the aca-miR-124 and aca-miR-146a-5p have a low level expression in L3 larvae but high level expression in L4 larvae. Transfection of aca-miR-124 mimics alone significantly downregulated the mRNA expression of IL-6 and IL-1β and TNF-a in the N9 cells, compared to the combination transfection of aca-miR-124 mimics and inhibitor (P < 0.05), suggesting that miR-124 of A. cantonensis have an important role in the suppression of microglia activation. In conclusion, the study presents a general picture of the expression of small RNAs in L3 and L4 of A. cantonensis and highlights conserved miRNAs differentially expressed between L3 and L4 larvae. Our data revealed that miRNAs of parasite may mediate important roles in A. cantonensis immune evasion and aca-miR-146a-5p can serve as a potential biomarker to diagnose angiostrongyliasis.
