Xenogeneic Testicular Cell Vaccination Induces Long-Term Anti-Cancer Immunity in Mice.
Article in Current issues in molecular biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Cancer/testis antigen (CTA) gene products are expressed in most malignant tumours, while under normal conditions their expression is primarily restricted to testicular cells. In this study, we investigated the prophylactic application of a xenogeneic (ram-derived) testicular cell (TC) vaccine for cancer prevention in an experimental animal model. C57BL/6 mice were immunised three times with either xenogeneic (ram) or syngeneic (mouse) formaldehyde-fixed spermatogenic tissue-derived cells. Following vaccination, mice were implanted with live B16 melanoma or LLC carcinoma cells. Tumour-bearing mice were subsequently assessed for survival and immunological parameters indicative of anti-cancer immunity. Xenogeneic vaccination with TCs induced cross-reactive immune responses to both B16 melanoma and LLC carcinoma antigens (Ags), as determined by an MTT ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Prophylactic vaccination with xenogeneic TCs (xTCs), but not syngeneic TCs (sTCs), significantly improved survival rates, with 30% of vaccinated mice surviving after LLC carcinoma implantation. The induced immunity was long-lasting as mice implanted with LLC carcinoma cells 3-6 months post-vaccination exhibited prolonged survival. Furthermore, lymphoid cells from surviving vaccinated mice were capable of adoptively transferring anti-cancer immunity to naïve animals, significantly increasing their survival rates upon subsequent LLC carcinoma cell implantation. Vaccinated mice bearing LLC tumours exhibited a reduction in regulatory CD4⁺CD25⁺Foxp3⁺ T cells in the spleen, with no effect observed in the central memory CD4⁺CD44⁺CD62L⁺ T-cell compartment. Moreover, vaccinated mice displayed increased interferon gamma (IFN-γ) levels in the blood, with no significant changes in interleukin-10 (IL-10) levels. Prophylactic vaccination with xenogeneic CTAs effectively induces long-term, stable anti-cancer immunity, demonstrating potential for future immunopreventive strategies.
