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

Small RNAs derived from mature tRNAs, referred to as tRNA fragments or "tRFs," are an emerging class of regulatory RNAs with poorly understood functions. We recently identified a role for one specific tRF-5' tRF-Gly-GCC, or tRF-GG-as a repressor of genes associated with the endogenous retroelement MERVL, but the mechanistic basis for this regulation was unknown. Here, we show that tRF-GG plays a role in production of a wide variety of noncoding RNAs-snoRNAs, scaRNAs, and snRNAs-that are dependent on Cajal bodies for stability and activity. Among these noncoding RNAs, regulation of the U7 snRNA by tRF-GG modulates heterochromatin-mediated transcriptional repression of MERVL elements by supporting an adequate supply of histone proteins. Importantly, the effects of inhibiting tRF-GG on histone mRNA levels, on activity of a histone 3' UTR reporter, and ultimately on MERVL regulation could all be suppressed by manipulating U7 RNA levels. We additionally show that the related RNA-binding proteins hnRNPF and hnRNPH bind directly to tRF-GG, and are required for Cajal body biogenesis, positioning these proteins as strong candidates for effectors of tRF-GG function in vivo. Together, our data reveal a conserved mechanism for 5' tRNA fragment control of noncoding RNA biogenesis and, consequently, global chromatin organization.
