Endogenous retrovirus envelope as a tumor-associated immunotherapeutic target in murine osteosarcoma.
Article in iScience, 2021. 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
Osteosarcoma remains one of the deadliest cancers in pediatrics and young adults. We administered two types of immunotherapies, oncolytic virotherapy and immune checkpoint inhibition, to two murine osteosarcoma models and observed divergent results. Mice bearing F420 showed no response, whereas those with K7M2 showed prolonged survival in response to combination therapy. K7M2 had higher expression of immune-related genes and higher baseline immune cell infiltrates, but there were no significant differences in tumor mutational burden or predicted MHC class I binding of nonsynonymous mutations. Instead, we found several mouse endogenous retrovirus sequences highly expressed in K7M2 compared with F420. T cell tetramer staining for one of them, gp70, was detected in mice with K7M2 but not F420, suggesting that endogenous retrovirus proteins are targets for the anti-tumor immune reaction. Given prior observations of endogenous retrovirus expression in human osteosarcomas, our findings may be translatable to human disease.
