1 · What the graph read from it

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.

2 · The registry

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

Cyclophilins belong to a group of proteins that have peptidyl-prolyl cis-trans isomerase activity and have been identified in all cell types and all organisms studied. In both prokaryotes and eukaryotes, they have been characterized as functional chaperones and involved in cell signaling. In the present study, Sj cyclophilin A (CyPA) was cloned, characterized, and subcloned into a prokaryotic expression vector to produce soluble recombinant rSjCyPA protein. qPCR analysis revealed that SjCyPA was expressed at each schistosome developmental stage tested, but reached its highest levels at days 7 and 13. In addition, the gene was also found to be significantly downregulated in adult worms from Microtus fortis. The SjCyPA protein was located on the subtegumental musculature of Schistosoma japonicum as determined by immunohistochemical staining analysis. Direct administration of recombinant SjCyPA to mice induced partial protective efficacy against subsequent schistosome infection. Length and width of adult worms and expression of SjCyPA were significantly decreased in the immunized groups, at 42 days post-infection, indicating that immunization with recombinant SjCyPA may suppress the schistosomes development. rSjCyPA can also react with sera from S. japonicum-infected rabbits at different time points. The data presented here suggest that SjCyPA may be an important molecule in the schistosome life-cycle and may be useful as a therapeutic target to treat schistosomiasis infection or as a potential diagnostic antigen.
