Alcoholics show reduced telomere length in the oesophagus
Bibliographic record
Abstract
Telomeres are repetitive G-rich DNA sequences located at the ends of chromosomes. Chromosomal and genomic instability due to telomere dysfunction plays an important role in carcinogenesis. To study telomere shortening in the oesophageal epithelium of alcoholics, we measured the telomere lengths of basal and parabasal cells in comparison with those of non-alcoholics using Q-FISH and our original software, Tissue Telo, and also assessed histological inflammation. Telomeres in basal cells were significantly shorter in alcoholics than in age-matched normal controls. Prominent histological findings of chronic inflammation were not evident in either alcoholics or non-alcoholics. Our finding that telomeres in the oesophageal epithelium are shorter in alcoholics than in non-alcoholics indicates that telomere shortening may be associated with the frequent occurrence of squamous cell carcinoma in alcoholics. Further studies to clarify the reason for the large annual loss of telomere length with rapid turnover or lower telomerase activity in the oesophageal epithelium of alcoholics will be necessary.

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.
