Potent antitumor effect elicited by superantigen-linked tumor cells transduced with heat shock protein 70 gene.
Article in Cancer science, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Heat shock proteins (HSP) induce antitumor-specific immunity via a unique mechanism, but HSP alone fails to produce a satisfactory antitumor efficacy. We considered that the potent immune-activation of superantigen (SAg) might assist HSP to elicit a strong tumor-antigen-specific immunity. We initially prepared B16 melanoma cells linked to SAg SEA via a fusion protein with a transmembrane sequence (TM), and demonstrated that SEA thus anchored on the tumor cell surface could elicit strong antitumor immunity. We then prepared cells transduced with an inducible heat shock protein 70 (HSP70) gene, and bearing SEA-TM fusion protein on the cell surface, and used these cells as a dual-modified vaccine. In this study, either in a therapeutic setting or in a pre-immune model, the SEA-anchored vaccine or the HSP70 gene-modified vaccine induced marked tumor suppression, prolonged survival, augmented lymphocyte proliferation and higher NK and CTL activity in C57BL/6 mice compared with their controls (P < 0.01), though they were less effective than the dual-modified vaccine. Among these vaccines, the dual-modified vaccine showed the best therapeutic efficacy in B16 melanoma-bearing mice and gave the greatest protection against wild-type B16 melanoma challenge. The results indicated that the dual-modified vaccine could induce a potent tumor-antigen-specific immune response in addition to an increase of non-specific immunity. This study offers a novel approach to bridging specific and non-specific immunity for cancer therapy.
