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

Nipah virus (NiV) is a non-segmented, negative-strand (NNS) RNA virus, belonging to Paramyxoviridae. The RNA polymerase complex, composed of large (L) protein and tetrameric phosphoprotein (P), is responsible for genome transcription and replication by catalyzing NTP polymerization, mRNA capping and cap methylation. Here, we determine the cryo-electron microscopy (cryo-EM) structure of fully bioactive NiV L-P polymerase complex at a resolution of 3.19 Å. The L-P complex displays a conserved architecture like other NNS RNA virus polymerases and L interacts with the oligomerization domain and the extreme C-terminus region of P tetramer. Moreover, we elucidate that NiV is naturally resistant to the allosteric L-targeting inhibitor GHP-88309 due to the conformational change in the drug binding site. We also find that the non-nucleotide drug suramin can inhibit the NiV L-P polymerase activity at both the enzymatic and cellular levels. Our findings have greatly enhanced the molecular understanding of NiV genome replication and transcription and provided the rationale for broad-spectrum polymerase-targeted drug design.
