Tracking the Dynamic Histone Methylation of H3K27 in Live Cancer Cells.
Article in ACS sensors, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Histone methylations play a crucial role in chromatin remodeling and genome regulations. However, there is a lack of tools to visualize these histone modifications with high spatiotemporal resolutions in live cells. We have developed a biosensor based on fluorescence resonance energy transfer (FRET) and incorporated it into nucleosomes, capable of monitoring the trimethylation of H3K27 (H3K27me3) in live cells. We also revealed that the performance of the FRET biosensor can be significantly improved by adjusting the linkers within the biosensor. An improved biosensor enables the live-cell imaging of different histone methylation status, induced by the suppressive H3.3K27M or existing in breast cancer cells with varying genetic backgrounds. We have further applied the biosensor to reveal the dynamic coupling between H3K27me3 changes and caspase activity representing the initiation of apoptosis in cancer cells by imaging both H3K27me3 and caspase activity simultaneously in the same live cells. Thus, this new FRET biosensor can provide a powerful tool to visualize the epigenetic regulation in live cells with high spatial temporal resolutions.
