Propagation, Purification, and In Vivo Testing of Oncolytic Vesicular Stomatitis Virus Strains
Bibliographic record
Abstract
Oncolytic viruses are self-amplifying therapeutics that specifically replicate in and kill cancer cells. We have previously shown that vesicular stomatitis virus (VSV) can be used as an oncolytic virus. A strain of VSV harboring a mutation in the M protein (VSVΔ51) was found to exhibit enhanced tumor selectivity over its wild-type counterpart due to its inability to overcome antiviral programs in normal cells and due to the frequent defects in antiviral signaling pathways observed in the majority of tumors. VSVΔ51 can harbor transgenes, is easily propagated and purified to high titers, and shows potent oncolytic activity in several mouse models, including syngeneic CT26-lacZ subcutaneous colon carcinoma models. However, VSV-neutralizing antibodies targeting mainly the VSV-G surface glycoprotein arise within 3-5 days following the initial dose. This should be considered for strategies aiming at increasing the effectiveness of VSV through delivery of additional doses of virus or aiming to prolong VSV replication in vivo.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
