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

In developing gene therapy for cystic fibrosis (CF) airways disease, a transgene encoding a partially deleted CF transmembrane conductance regulator (CFTR) Cl- channel could be of value for vectors such as adeno-associated virus that have a limited packaging capacity. Earlier studies in heterologous cells indicated that the CFTR R (regulatory) domain is predominantly random coil and that parts of the R domain can be deleted without abolishing channel function. Therefore, we designed a series of CFTR variants with shortened R domains (between residues 708 and 835) and expressed them in well-differentiated cultures of CF airway epithelia. All of the variants showed normal targeting to the apical membrane, and for the constructs we tested, biosynthesis was like wild type. Moreover, all constructs generated transepithelial Cl- current in CF epithelia. Comparison of the Cl- transport suggested that the length of the R domain, the presence of phosphorylation sites, and other factors contribute to channel activity. A variant deleting residues 708-759 complemented CF airway epithelia to the same extent as wild-type CFTR and showed no current in the absence of cAMP stimulation. In addition, expression in nasal mucosa of CF mice corrected the Cl- transport defect. These data provide insight into the structure and function of the R domain and identify regions that can be deleted with retention of function. Thus they suggest a strategy for shortening the transgene used in CF gene therapy.
