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

One of the most important rapidly emerging mosquito-borne alphavirus is Chikungunya virus (CHIKV). There is a necessity to develop anti-CHIKV therapeutics, as neither antiviral drug nor vaccines have been licensed yet. Several CHIKV proteins are being studied worldwide, but non-structural protein 3 (nsP3) has been less explored. This protein consists of three domains: macrodomain, alphavirus unique domain (AUD) and hypervariable region (HVR). The proline-rich regions of HVR contain SRC homology 3 (SH3)-binding domain which is essential for its functionality. Interaction of these motifs with host amphiphysin protein is crucial for viral RNA replication. Restricting the interactions of HVR could lead to inhibition of viral life cycle. Therefore, the present study focuses on purification of HVR protein and its structural and functional assay for therapeutic intervention in future use. In order to obtain purified protein, HVR region was amplified from TOPO clones of nsP3 of IND-06-Guj strain and cloned into expression vector. Expression and solubilization of the protein were optimized at various conditions of salt, detergent and imidazole before purification. The soluble recombinant HVR (His-HVR) protein was purified using affinity chromatography. Purified protein was analyzed for structural studies and functional assays. Circular dichroism of His-HVR protein was performed for structural study, and it was observed that it consists of mostly random coils. For functional assay, co-pull down of His-HVR protein was performed with endogenous amphiphysin-I protein of N2a cells and was analyzed using Western blotting. This purified protein obtained could be used as a potential target reagent for novel therapeutic interventions in the future.
