AMP-activated kinase regulates porcine reproductive and respiratory syndrome virus infection in vitro.
Article in Virus genes, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Porcine reproductive and respiratory syndrome virus (PRRSV) is an economically important pathogen in the pig industry worldwide. Many viruses manipulate their cellular metabolism to replicate themselves and cause infection. A conserved cellular energy sensor, 5'-AMP-activated protein kinase (AMPK), maintains cellular energy homeostasis. We found that PRRSV infection caused significant AMPK activation in a time-dependent manner via the ROS-calcium/calmodulin-dependent protein kinase-2 pathway. RNA interference-mediated AMPK knockdown could increase PRRSV replication in MARC-145 cells, suggesting that AMPK contributed to PRRSV infection regulation. Moreover, investigation of the effect of AMPK activity on PRRSV replication showed that PRRSV replication could be suppressed by the pharmacological agonists 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside and A769662. Conversely, an AMPK inhibitor, compound C, markedly enhanced PRRSV infection. Furthermore, the AMPK agonist A769662 was found to exert no effect on PRRSV entry, assembly, and release, suggesting that A769662 may hinder the PRRSV genome replication in MARC-145 cells. In conclusion, AMPK may be a promising antiviral drug target against PRRSV infection.
