The Influence of Pigment Transfer on the Risk of Developing Melanoma: The Significance of the Melanocyte Amputation Cycle
Bibliographic record
Abstract
It has been shown that cancer incidence is not only a function of the size of the population at risk but is strongly associated with the turnover rate of the tissue concerned. There is a strong negative correlation between melanoma incidence and the degree of skin pigmentation, and yet the melanocyte density is the same for all races. The proposal advanced in this communication is that the probability of undergoing malignant change is critically dependent on the melanocyte turnover and that this is regulated by the pigmentation process. In melanocytes, the division rate is influenced by the process of pigment donation, probably by a mechanism whereby the continual cytoplasmic loss due to cytocrine transfer of melanosomes (termed the ‚Amputation Cycle‚) inhibits replication. Consequently the turnover of melanocyte stem cells in heavily pigmented epidermis will be diminished, and this is held to account for the strong negative correlation between the degree of skin pigmentation and melanoma incidence.

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.
