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

Complex genomic rearrangements (CGRs) are a hallmark of many human diseases. Recently, CGRs were suggested to result from microhomology-mediated break-induced replication (MMBIR), a replicative mechanism involving template switching at positions of microhomology. Currently, the cause of MMBIR and the proteins mediating this process remain unknown. Here, we demonstrate in yeast that a collapse of homology-driven break-induced replication (BIR) caused by defective repair DNA synthesis in the absence of Pif1 helicase leads to template switches involving 0-6 nt of homology, followed by resolution of recombination intermediates into chromosomal rearrangements. Importantly, we show that these microhomology-mediated template switches, indicative of MMBIR, are driven by translesion synthesis (TLS) polymerases Polζ and Rev1. Thus, an interruption of BIR involving fully homologous chromosomes in yeast triggers a switch to MMBIR catalyzed by TLS polymerases. Overall, our study provides important mechanistic insights into the initiation of MMBIR associated with genomic rearrangements, similar to those promoting diseases in humans.
