Analysis of alternative lengthening of telomere markers in BRCA1 defective cells.
Article in Genes, chromosomes & cancer, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Telomeres are specialized structures responsible for the chromosome end protection. Previous studies have revealed that defective BRCA1 may lead to elevated telomere fusions and accelerated telomere shortening. In addition, BRCA1 associates with promyelocytic leukemia (PML) bodies in alternative lengthening of telomeres (ALTs) positive cells. We report here elevated recombination rates at telomeres in cells from human BRCA1 mutation carriers and in mouse embryonic stem cells lacking both copies of functional Brca1. An increased recombination rate at telomeres is one of the signs of ALT. To investigate this possibility further we employed the C-circle assay that identifies ALT unequivocally. Our results revealed elevated levels of ALT activity in Brca1 defective mouse cells. Similar results were obtained when the same cells were assayed for the presence of another ALT marker, namely the frequency of PML bodies. These results suggest that BRCA1 may act as a repressor of ALT. © 2016 The Authors Genes, Chromosomes & Cancer Published by Wiley Periodicals, Inc.
