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

In trypanosomes the C/D- and H/ACA-like small nucleolar RNAs (snoRNAs) are clustered and repeated in the genome. The snoRNAs studied to date are transcribed as polycistronic transcripts by RNA polymerase II and then processed, resulting in mature snoRNAs. In this study we demonstrated that snoRNA genes can be silenced in three trypanosomatid species: Leptomonas collosoma, Leishmania major, and Trypanosoma brucei. Silencing was achieved in L. collosoma and L. major by the expressing of an antisense transcript complementary to the snoRNA gene and was accompanied by the accumulation of small interfering RNA. Silencing eliminated the mature snoRNA but not its precursor and abolished the specific 2'-O-methylation guided by the snoRNA. In T. brucei, silencing was achieved by using the inducible synthesis of double-stranded RNA from T7 opposing promoters. Silencing varied between the different snoRNA genes, which may reflect the accessibility of small interfering RNA to the target RNAs. This study suggests that RNA interference can degrade snoRNAs. This study has further implications in elucidating the function of nucleolar RNAs and specific modifications guided by these RNAs in trypanosomatids and perhaps in other eukaryotes as well.
