Adenovirus E1B 55-Kilodalton Protein Targets SMARCAL1 for Degradation during Infection and Modulates Cellular DNA Replication.
Article in Journal of virology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Here, we show that the cellular DNA replication protein and ATR substrate SMARCAL1 is recruited to viral replication centers early during adenovirus infection and is then targeted in an E1B-55K/E4orf6- and cullin RING ligase-dependent manner for proteasomal degradation. In this regard, we have determined that SMARCAL1 is phosphorylated at S123, S129, and S173 early during infection in an ATR- and CDK-dependent manner, and that pharmacological inhibition of ATR and CDK activities attenuates SMARCAL1 degradation. SMARCAL1 recruitment to viral replication centers was shown to be largely dependent upon SMARCAL1 association with the RPA complex, while Ad-induced SMARCAL1 phosphorylation also contributed to SMARCAL1 recruitment to viral replication centers, albeit to a limited extent. SMARCAL1 was found associated with E1B-55K in adenovirus E1-transformed cells. Consistent with its ability to target SMARCAL1, we determined that E1B-55K modulates cellular DNA replication. As such, E1B-55K expression initially enhances cellular DNA replication fork speed but ultimately leads to increased replication fork stalling and the attenuation of cellular DNA replication. Therefore, we propose that adenovirus targets SMARCAL1 for degradation during infection to inhibit cellular DNA replication and promote viral replication.
