NSP7 Molecular Degrader Attenuates Coronaviral Infection Through the β-TrCP1/FBXO5 Axis.

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
NSP7 (Non-Structural Protein 7) of SARS-CoV-2 is a crucial component for viral replication and transcription. In this study, it is revealed that the host E3 ubiquitin ligase FBXO5 suppresses viral replication by mediating NSP7 lysine-48-linked ubiquitination and subsequent proteasomal degradation. Interestingly, it is also determined that NSP7 expression impairs the host antiviral response by inhibiting the ISGylation of melanoma differentiation-associated protein 5 (MDA5), a key sensor for viral RNA. Through an unbiased esiRNA screen, it is identified that NSP7 ubiquitination is coregulated by β-TrCP1 and the kinase TAF1. Additionally, this study uncovers a small molecule FBXO5 stabilizer that disrupts the β-TrCP1-FBXO5 interaction, thereby markedly enhancing NSP7 degradation and effectively mitigating SARS-CoV-2 infection. Taken together, the findings reveal a novel mechanism for NSP7 regulation and suggest that small-molecule activators of the E3 ubiquitin ligase FBXO5 represent a promising new class of host-directed antiviral therapies.
