Enhanced antitumor activity of a combination of <i>MBD2</i>‐antisense electrotransfer gene therapy and bleomycin electrochemotherapy
Bibliographic record
Abstract
BACKGROUND: MBD2 is a methylated DNA-binding protein that has been previously suggested to have transcriptional silencing as well as DNA demethylase activities. We have previously shown that electrotransfer of an MBD2-antisense encoding plasmid inhibits tumor growth in vivo. In this study we tested whether a combination of MBD2-antisense gene therapy and bleomycin chemotherapy has an augmented antitumor effect in comparison with either monotherapy. METHODS: Mice bearing human non-small-cell lung carcinoma line H1299 xenoplants were treated with electrotransfer of either bleomycin or MBD2-antisense expression plasmid or a combination of both therapies and tumor growth following treatment was monitored. RESULTS: A combination of electrotransfer of MBD2-antisense and bleomycin electrochemotherapy has an additive inhibitory effect on the rate of tumor growth and a synergistic effect on the number of tumor-free animals when compared with either monotherapy. CONCLUSIONS: Our results suggest that a combination of MBD2-antisense electrotransfer gene therapy and chemotherapy with bleomycin is a candidate new approach to anticancer therapy.

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.
