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

Transposable elements (TEs) have the capacity to replicate and insert into new genomic locations. This contributs significantly to evolution of genomes, but can also result in DNA breaks and illegitimate recombination, and therefore poses a significant threat to genomic integrity. Excess damage to the germ cell genome results in sterility. A specific RNA silencing pathway, termed the piRNA pathway operates in germ cells of animals to control TE activity. At the core of the piRNA pathway is a ribonucleoprotein complex consisting of a small RNA, called piRNA, and a protein from the PIWI subfamily of Argonaute nucleases. The piRNA pathway relies on the specificity provided by the piRNA sequence to recognize complementary TE targets, while effector functions are provided by the PIWI protein. PIWI-piRNA complexes silence TEs both at the transcriptional level - by attracting repressive chromatin modifications to genomic targets - and at the posttranscriptional level - by cleaving TE transcripts in the cytoplasm. Impairment of the piRNA pathway leads to overexpression of TEs, significantly compromised genome structure and, invariably, germ cell death and sterility.The piRNA pathway is best understood in the fruit fly, Drosophila melanogaster, and in mouse. This Chapter gives an overview of current knowledge on piRNA biogenesis, and mechanistic details of both transcriptional and posttranscriptional TE silencing by the piRNA pathway. It further focuses on the importance of post-translational modifications and subcellular localization of the piRNA machinery. Finally, it provides a brief description of analogous pathways in other systems.
