TMPRSS2 and SARS-CoV-2 SPIKE interaction assay for uHTS.
Article in Journal of molecular cell biology, 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
SARS-CoV-2, the coronavirus that causes the disease COVID-19, has claimed millions of lives over the past 2 years. This demands rapid development of effective therapeutic agents that target various phases of the viral replication cycle. The interaction between host transmembrane serine protease 2 (TMPRSS2) and viral SPIKE protein is an important initial step in SARS-CoV-2 infection, offering an opportunity for therapeutic development of viral entry inhibitors. Here, we report the development of a time-resolved fluorescence/Förster resonance energy transfer (TR-FRET) assay for monitoring the TMPRSS2-SPIKE interaction in lysate from cells co-expressing these proteins. The assay was configured in a 384-well-plate format for high-throughput screening with robust assay performance. To enable large-scale compound screening, we further miniaturized the assay into 1536-well ultrahigh-throughput screening (uHTS) format. A pilot screen demonstrated the utilization of the assay for uHTS. Our optimized TR-FRET uHTS assay provides an enabling platform for expanded screening campaigns to discover new classes of small-molecule inhibitors that target the SPIKE and TMPRSS2 protein-protein interaction.
