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

backgroundPlasmid construction of small fragments of interest (such as insertion of small fragment marker genes, expression of shRNA, siRNA, etc) is the basis of many biomolecular experiments. Here, we describe a method to clone short DNA into vectors by polymerase chain reaction (PCR), named one-step PCR cloning. Our method uses PCR to amplify the entire circular plasmid. The PCR was performed by the primers containing the gene of short DNA with overlapping sequences between 10-15 bp. The PCR products were then transformed into E. coli and cyclized by homologous recombination in vivo.

methodsThe pEGFP-N1-HA plasmid was constructed by one-step PCR and transformation. Cells were transfected with pEGFP-N1-HA and pEGFP-N1 plasmid using TurboFect transfection reagent. Protein expression was detected by western blotting and the HA-GFP fusion protein was detected by confocal microscopy.

resultsThe pEGFP-N1-HA plasmid was successfully constructed and HA expression in cells.

conclusionsFree from the limitations of restriction enzyme sites and omitting the ligation process, our method offers a flexible and economical option of plasmid construction. KEY POINTS: Significant findings of the study A method to clone short DNA into plasmids was found. What this study adds Our study provides a flexible and economical option to clone short DNA into plasmids.
