The role of ICP0-Null HSV-1 and interferon signaling defects in the effective treatment of breast adenocarcinoma
Bibliographic record
Abstract
Oncolytic viruses that selectively replicate in cancer cells have been described for over 50 years. Despite the observation by several groups that multimutated herpes simplex type 1 vectors are oncolytic in a variety of murine tumor models, the oncolytic potential of ICP0 null mutants has not been described. This study characterizes a novel second-generation oncolytic herpes simplex type 1 vector null for the ICP0 gene. We tested three mutant viruses and found that all were selectively cytotoxic in a variety of human and murine tumor cells in vitro. Furthermore, we provide evidence of a mechanistic link between ICP0's function in interferon signaling pathways and the observed oncolytic capacity of ICP0 mutants. Using an immunocompetent murine model of breast adenocarcinoma we demonstrate that the ICP0 mutant KM100 completely eradicates tumors in approximately 80% of treated animals and significantly increases survival. Our data suggest that active viral replication is necessary for effective tumor regression. In addition, we characterized the potential of KM100 as an anti-tumor vaccine since cured mice were found to elicit a robust anti-tumor immune response and were refractory to subsequent tumor growth upon rechallenge.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
