Human tumor-derived genomic DNA transduced into a recipient cell induces tumor-specific immune responses ex vivo.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
This article describes a DNA-based vaccination strategy evaluated ex vivo with human cells. The vaccine was prepared by transferring tumor-derived genomic DNA to PCI-13 cells, a highly immunogenic tumor cell line ("recipient cell"), which had been genetically modified to secrete IL-2 (PCI-13/IL-2). PCI-13 cells expressed class I MHC determinants (HLA-A2) shared with the tumor from which the DNA was obtained as well as allogeneic determinants. DNA from a gp100(+) melanoma cell line was transduced into gp100(-) PCI-13/IL-2 cells (PCI-13/IL-2/DNA). A T cell line specific for the gp100 epitope responded to PCI-13/IL-2/DNA cells by IFN-gamma-secretion measured in enzyme-linked immunospot assays. The T cell line also recognized the gp100 epitope presented by dendritic cells that ingested PCI-13/IL-2/DNA cells, which had been induced by UVB irradiation to undergo apoptosis. After up-take and processing of apoptotic PCI-13/IL-2/DNA cells, the dendritic cells primed normal peripheral blood lymphocytes to generate effector T cells specific for the tumor donating the DNA. The results indicate that tumor epitopes encoded in such DNA are expressed in recipient cells and can induce tumor-specific T cells. The findings support translation of this vaccination strategy to a phase I trial in patients with cancer.
