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

The marine hyperthermophilic crenarchaeon Ignicoccus hospitalis supports the propagation on its surface of Nanoarchaeum equitans, an evolutionarily enigmatic archaeon that resembles highly derived parasitic and symbiotic bacteria. The cellular and molecular mechanisms that enable this interarchaea relationship and the intimate physiologic consequences to I. hospitalis are unknown. Here, we used concerted proteomic and transcriptomic analyses to probe into the functional genomic response of I. hospitalis as N. equitans multiplies on its surface. The expression of over 97% of the genes was detected at mRNA level and over 80% of the predicted proteins were identified and their relative abundance measured by proteomics. These indicate that little, if any, of the host genomic information is silenced during growth in the laboratory. The primary response to N. equitans was at the membrane level, with increases in relative abundance of most protein complexes involved in energy generation as well as that of several transporters and proteins involved in cellular membrane stabilization. Similar upregulation was observed for genes and proteins involved in key metabolic steps controlling nitrogen and carbon metabolism, although the overall biosynthetic pathways were marginally impacted. Proliferation of N. equitans resulted, however, in selective downregulation of genes coding for transcription factors and replication and cell cycle control proteins as I. hospitalis shifted its physiology from its own cellular growth to that of its ectosymbiont/parasite. The combination of these multiomic approaches provided an unprecedented level of detail regarding the dynamics of this interspecies interaction, which is especially pertinent as these organisms are not genetically tractable.
