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

The centromere is a specialized chromosomal locus required for accurate chromosome segregation. A specific histone H3 variant, CENP-A, assembles at centromeres. CENP-A is required for kinetochore protein assembly and is an epigenetic marker for the maintenance of a functional centromere. Human CENP-A chromatin normally assembles on α-satellite DNA (alphoid DNA), a centromeric repetitive sequence. Using alphoid DNA arrays, human artificial chromosomes (HACs) have been constructed in human HT1080 cells and used to dissect the requirements for CENP-A assembly on DNA sequence. However, centromere formation is not a simple genetic event. In other commonly used human cell lines, such as HeLa and U2OS cells, no functional de novo centromere formation occurs efficiently with the same centromeric alphoid DNA sequences. Recent studies using protein tethering combined with the HAC system and/or genetic manipulation have revealed that epigenetic chromatin regulation mechanisms are also involved in the CENP-A chromatin assembly pathway and subsequent centromere/kinetochore formation. We summarize the DNA sequence requirements for CENP-A assembly and discuss the epigenetic regulation of human centromeres.
