Induction of CD4 expression and human immunodeficiency virus type 1 replication by mutants of the interferon-inducible protein kinase PKR.
Article in Journal of virology, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Replication of the human immunodeficiency virus type 1 (HIV-1) is inhibited by interferons (IFNs), and the IFN-inducible protein kinase PKR is thought to mediate this effect by regulating protein synthesis. Here we report that ectopic expression of dominant negative PKR mutants in Jurkat cells induces HIV-1 replication. Specifically, expression of CD4 is upregulated by the PKR mutants, and this correlates with an induction of HIV-1 binding and proviral DNA synthesis upon HIV-1 infection. Moreover, activation of NF-kappaB was induced by an RNA binding-defective mutant of PKR. Thus, it appears that PKR, in addition to translational control, is involved in HIV-1 replication by modulating virus binding through the regulation of CD4 expression and virus gene expression through the activation of NF-kappaB.
