The screening of compounds regulating PD-L1 transcriptional activity in a cell functional high-throughput manner.
Article in Cancer medicine, 2023. 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
Immune checkpoints are protein molecules expressed on the immune cell membrane, which regulate the immune system to kill tumor cells. As an essential immune checkpoint, overexpressed PD-1 on tumor cells could inhibit T-cell activation after being bonded to PD-1. Due to this inhibitory effect, T-cell proliferation and cytokine secretion are suppressed, leading to immune escape of tumor cells. Here, we established a high-throughput method based on cell function screening technology to screen drugs regulating PD-L1 expression in tumor cells at the transcriptional level. After two screening rounds, 12 compounds that enhanced PD-L1 transcription while seven weakened were sorted out among 1018 FDA-approved drugs. Finally, a tumor cell line was used to verify the upregulation of endogenous PD-L1 expression for a drug named "vorinostat," a histone deacetylation inhibitor, after the two rounds of optional selection. Therefore, our research provides another perspective for using "vorinostat" in treating tumors and offers a convenient method to detect the transcriptional expression of other intracellular proteins besides PD-L1.
