Intratumoral injection of interferon-gamma gene-modified dendritic cells elicits potent antitumor effects: effective induction of tumor-specific CD8+ CTL response.

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
purposeTo examine the antitumor efficacy of intratumoral injection of interferon-gamma gene-modified dendritic cells (DC-IFN-gamma) in a B16 melanoma model and to investigate its related immunological mechanisms.
methodsC57BL/6 mice-derived DC were transfected with adenovirus encoding IFN-gamma or beta-galactosidase (DC-LacZ). Secretion of IFN-gamma and TNF-alpha by DC was detected by ELISA. Nitric oxide (NO) production was measured by Griess reaction. Cytotoxicity of DC against tumor cell lines and activity of cytotoxic T lymphocytes (CTLs) were determined by 51Cr-release assay. TRP-2aa180-188-specific CD8+ CTLs in tumor-bearing mice with different treatment were determined by ELISPOT.
resultsDC-IFN-gamma could secrete high levels of IFN-gamma, NO and TNF-alpha. DC-IFN-gamma were cytolytic to B16 melanoma cells in vitro, but DC-LacZ and DC were not. Significant inhibition of tumor growth and prolonged survival were achieved in tumor-bearing mice intratumorally injected with DC-IFN-gamma when compared with those in tumor-bearing mice intratumorally injected with DC, DC-LacZ, fibroblasts, IFN-gamma gene-modified fibroblasts or PBS. After treatment with DC-IFN-gamma, enhanced Th1 and decreased Th2 responses were observed, and B16 melanoma antigen TRP-2aa180-188-specific CD8+ CTLs were induced significantly in the tumor-bearing mice.
conclusionsIntratumorally injected DC-IFN-gamma can uptake tumor antigens in situ and cross-present tumor antigens to specific CD8+ T cells, hereby eliciting effective antitumor effects in murine model with preestablished B16 melanoma.
