Development of cell-based high throughput luminescence assay for drug discovery in inhibiting OCT4/DNA-PKcs and OCT4-MK2 interactions.

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
Amplification-independent c-MYC overexpression is suggested in multiple cancers. Targeting c-MYC activity has therapeutic potential, but efforts thus far have been mostly unsuccessful. To find a druggable target to modulate c-MYC activity in cancer, we identified two kinases, MAPKAPK2 (MK2) and the DNA-dependent protein kinase catalytic subunit (DNA-PKcs), which phosphorylate the Ser111 and the Ser93 residues of OCT4, respectively, to transcriptionally activate c-MYC. Using these observations, we present here a novel cell-based luminescence assay to identify compounds that inhibit the interaction between these kinases and OCT4. After screening approximately 80,000 compounds, we identified 56 compounds ("hits") that inhibited the luminescence reaction between DNA-PKcs and OCT4, and 65 hits inhibiting the MK2-OCT4 interaction.
