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

Somatic cell reprogramming has generated enormous interest, following the first report of generation of induced pluripotent stem cells (iPSCs) from mouse fibroblasts, but the integration of viral transgenes into the genome is unlikely to be accepted. Given these safety considerations, a method for virus-free transient gene expression from suspension-adapted Sf9 insect cells was developed. Here, we expressed transactivator of transcription (TAT)-fused proteins, Sox2, Oct4, Lin28, and Nanog in Sf9 cells using the baculovirus expression vector system (BEVS). The molecular weights of the TAT-Sox2, TAT-Oct4, TAT-Lin28, and TAT-Nanog fusion proteins were 36kD, 40kD, 24kD, and 36kD, respectively. Further investigation indicated that most of the recombinant proteins remained in the nuclei of the Sf9 insect cells and were therefore unavailable for purification and cellular reprogramming. Once this problem has been solved, it seems likely that protein expressed from baculovirus-infected Sf9 insect cells will be the method of choice for cellular reprogramming.
