Imaging-Based In Situ Analysis of 5-Methylcytosine at Low Repetitive Single Gene Loci with Transcription-Activator-Like Effector Probes.

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
Transcription-activator-like effectors (TALEs) are programmable DNA binding proteins that can be used for sequence-specific, imaging-based analysis of cellular 5-methylcytosine. However, this has so far been limited to highly repetitive satellite DNA. To expand this approach to the analysis of coding single gene loci, we here explore a number of signal amplification strategies for increasing imaging sensitivity with TALEs. We develop a straightforward amplification protocol and employ it to target the MUC4 gene, which features only a small cluster of repeat sequences. This offers high sensitivity imaging of MUC4, and in costaining experiments with pairs of one TALE selective for unmethylated cytosine and one universal control TALE enables analyzing methylation changes in the target independently of changes in target accessibility. These advancements offer prospects for 5-methylcytosine analysis at coding, nonrepetitive gene loci by the use of designed TALE probe collections.
