Characterization of a cancer-associated Epstein-Barr virus EBNA1 variant reveals a novel interaction with PLOD1 and PLOD3
Bibliographic record
Abstract
Whole genome sequence analysis of Epstein-Barr virus genomes from tumours and healthy individuals identified three amino acid changes in EBNA1 that are strongly associated with gastric carcinoma and nasopharyngeal carcinoma. Here we show that, while these mutations do not impact EBNA1 plasmid maintenance function, one of them (Thr85Ala) decreases transcriptional activation and results in a gain of function interaction with PLOD1 and PLOD3. PLOD family proteins are strongly linked to multiple cancers, and PLOD1 is recognized as a prognostic marker of gastric carcinoma. We identified the PLOD1 binding site in EBNA1as the N-terminal transactivation domain and show that lysine 83 is critical for this interaction. The results provide a novel link between EBV infection and the cancer-associated PLOD proteins.

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.
