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

Vesicular stomatitis virus (VSV) is being developed for cancer therapy. We created a recombinant replicating VSV (rrVSV) that preferentially infected Her2/neu-expressing breast cancer cells. This rrVSV did not express the native VSV-G glycoprotein (gp). Instead, it expressed a chimeric Sindbis gp which included a single-chain antibody (SCA) directed to the human Her2/neu receptor. The virus infected mouse mammary carcinoma cells (D2F2/E2) expressing Her2/neu 23-fold better than the parent cells (D2F2). However, viral growth in cultured D2F2/E2 cells was curtailed after several cycles, and viral yield was very poor at 2 x 10(4) infectious doses (ID)/ml. We performed in vitro serial passage in D2F2/E2 cells to evolve a virus with improved growth that could be used for preclinical therapy trials in mice. Fifteen passes generated an adapted virus that progressed through multiple cycles in cultured D2F2/E2 cells until all cells were infected and had a viral yield of 1 x 10(8) ID/ml. Sequencing of the entire viral genomes found only 2 mutations in the adapted virus. Both mutations occurred in the gp gene segment coding for the SCA. An additional N-glycosylation site was created by one of the mutations. The adapted virus showed higher density of gp on the viral envelope, improved infectivity, much greater stability, higher burst size, and decreased induction of cellular interferon. The specificity for cells expressing the Her2/neu receptor was unchanged. These studies demonstrate that serial passage can be used to rapidly evolve a VSV genome encoding an improved chimeric glycoprotein.
