Generation of New M2e-HA2 Fusion Chimeric Peptide to Development of a Recombinant Fusion Protein Vaccine.
Article in Advanced pharmaceutical bulletin, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe purpose was to design a new construction containing influenza virus (H1N1) M2e gene and HA2 gene by bioinformatics approach, cloning the construct in to Escherichia coli and produce M2e-HA2 peptide.
methodsThe procedure was done by virus cultivation in SPF eggs, hemagglutination assay (HA), RNA isolation, RT-PCR, primers designed (DNAMAN 4 and Oligo7), virtual fusion construction translation (ExPASy), N-Glycosylated sites prediction (Ensemblegly-Iowa), complete open reading frame (ORF), stop codon studied (NCBI ORF Finder), rare codon determination (GenScript), Solvent accessibility of epitopes (Swiss-PdbViewer), antigenic sites prediction (Protean), fusion PCR of M2e-HA2 gene, sequence analysis, nested PCR, gel electrophoresis, double digestion of pET22b(+) plasmid and the fusion construct, ligation of them, transformation of the ligated vector (pET22b-M2e-HA2) to E.coli (BL21), mass culture the cloned bacterium ,induction the expression by isopropyl-beta-D-thiogalactopyranoside (IPTG), sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), purification the fusion peptide by Ni-NTA column, western blot to verify the purification.
resultsIn this study we developed a new approach for fusion of Influenza virus M2e (96 nucleotides) and HA2 (663 nucleotides) genes based on fusion PCR strategy and produced a fused fragment with 793 nucleotides. The construct was successfully cloned and expressed.
conclusionThis construct is a 261 amino acid chimeric fusion peptide with about 30 KD molecular weight. According on the latest information; this is the first case of expression and purification M2e-HA2 fusion chimeric peptide, which could be used for development of a recombinant M2e-HA2 fusion protein vaccine.
