Intercellular trafficking and cytotoxicity of recombinant HSV-1 thymidine kinase fused with HSV-2 US11 RXP repeat peptide.
Article in Virus genes, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
To improve the therapeutic efficacy of herpes simplex virus type 1 (HSV-1) thymidine kinase (tk)/ganciclovir (GCV) therapy, we have made recombinant tk chimeras fused with the arginine-rich (RXP) repeat of herpes simplex virus type 2 (HSV-2) US11 and examined their activity of intercellular trafficking and cytotoxicity. When examined the immunofluorescence staining patterns of RXP/tk fusion proteins in transfected COS7 cells, the RXP chimeras revealed a conservation of the trafficking activity of RXP. We also found that transfection of tkC Delta 6-RXP (lacking the C-terminal six amino residues of tk), tk-RXP, and tkN Delta 66-RXP (lacking the N-terminal 66 amino residues of tk) induced apoptosis even in the absence of GCV. The results suggest that these tk/RXP chimeras themselves have apoptosis-inducing activity, and that the HSV tk nucleoside-binding domain may be involved in the induction of apoptosis. Furthermore, treatment with 5 muM GCV induced efficient cell death in cells tranfected with tk-RXP in comparison to the cells transfected with tk (P < 0.0001).
