Modulation of type I interferon induction by porcine reproductive and respiratory syndrome virus and degradation of CREB-binding protein by non-structural protein 1 in MARC-145 and HeLa cells.

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
Porcine reproductive and respiratory syndrome (PRRS) is an emerged disease of swine characterized by negligible response of type I IFNs and viral persistence. We show that the PRRSV non-structural protein 1 (Nsp1) is the viral component responsible for modulation of IFN response. Nsp1 blocked dsRNA-induced IRF3 and IFN promoter activities. Nsp1 did not block phosphorylation and nuclear translocation of IRF3 but inhibited IRF3 association with CREB-binding protein (CBP) in the nucleus. While IRF3 was stable, CBP was degraded, and CBP degradation was proteasome-dependent, suggesting that CBP degradation is not due to the protease activity of Nsp1 but an intermediary is involved. Our data suggest that the Nsp1-mediated CBP degradation inhibits the recruitment of CBP for enhanceosome assembly, leading to the block of IFN response. CBP degradation is a novel strategy for viral evasion from the host response, and Nsp1 may form a new class of viral antagonists for IFN modulation.
