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

Rad24-RFC (replication factor C) loads the 9-1-1 checkpoint clamp onto the recessed 5' ends by binding a 5' DNA at an external surface site and threading the 3' single-stranded DNA (ssDNA) into 9-1-1. We find here that Rad24-RFC loads 9-1-1 onto DNA gaps in preference to a recessed 5' end, thus presumably leaving 9-1-1 on duplex 3' ss/double-stranded DNA (dsDNA) after Rad24-RFC ejects from DNA. We captured five Rad24-RFC-9-1-1 loading intermediates using a 10-nt gap DNA. We also determined the structure of Rad24-RFC-9-1-1 using a 5-nt gap DNA. The structures reveal that Rad24-RFC is unable to melt DNA ends and that a Rad24 loop limits the dsDNA length in the chamber. These observations explain Rad24-RFC's preference for a preexisting gap of over 5-nt ssDNA and suggest a direct role of the 9-1-1 in gap repair with various TLS (trans-lesion synthesis) polymerases in addition to signaling the ATR kinase.
