In vitro and in vivo effects of polyhaemoglobin–tyrosinase on murine B16F10 melanoma
Bibliographic record
Abstract
Melanoma is an increasingly common fatal skin cancer. Many groups are carrying out research on potential treatments for melanoma. One of these approaches has shown that lowering tyrosine can inhibit the growth of melanoma in cell cultures and of B16BL6 melanoma in mice. However, humans cannot tolerate tyrosine-restricted diets for lowering tyrosine because of nausea, vomiting and weight loss. We report here our preparation and characterization of a novel soluble polyhaemoglobin-tyrosinase complex. This preparation prevents native tyrosinase from having adverse effects and from rapid removal after injection. The preparation inhibited murine B16F10 melanoma cell growth in culture and delayed its growth in a mice model. Intravenous injection of the preparation lowers the systemic tyrosine level without causing adverse effects such as vomiting and weight loss in mice. It is therefore possible that this complex could be useful in the treatment of human melanoma.

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.
