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

We exploited the Drosophila Amplicon in Follicle Cells, DAFC-62D, to identify a new metazoan amplification origin, ori62. In addition to the origin, DAFC-62D contains two other developmental stage-specific binding regions for the Origin Recognition Complex (ORC) and the replicative helicase MCM2-7. All three of these regions are required for proper amplification. There are two rounds of amplification initiation at ori62, and the second round is preceded by transcription across ori62. We show by alpha-amanitin inhibition that RNA polymerase II (RNAPII) transcription is required to localize MCM2-7 (but not ORC) to permit the second round of origin firing. This role for transcription appears unique to DAFC-62D, because neither other DAFCs nor ectopic transposons with the DAFC-62D replication elements bounded by functional chromatin insulators are affected by alpha-amanitin. By sequential chromatin immunoprecipitation, we show that the MCM complex and RNAPII are bound to the same 100-500 bp pieces of chromatin during late origin firing. These results raise the possibility that RNAPII may recruit MCM2-7 at some metazoan replication origins.
