Selected Telomere Length Changes and Aberrant Three-dimensional Nuclear Telomere Organization during Fast-Onset Mouse Plasmacytomas
Bibliographic record
Abstract
Mouse plasmacytoma (PCT) can develop within 45 days when induced by a v-abl/myc replication-deficient retrovirus. This fast-onset PCT development is always associated with trisomy of cytoband E2 of mouse chromosome 11 (11E2). Trisomy of 11E2 was identified as the sole aberration in all fast-onset mouse PCTs in [T38HxBALB/c]N congenic mice, with a reciprocal translocation between chromosome X and 11 (rcpT(X;11)) (Genes Cancer 2010;1:847-858). Using this mouse model, we have now examined the overall and individual telomere lengths in fast-onset PCTs compared with normal B cells using two-dimensional and three-dimensional quantitative fluorescent in situ hybridization of telomeres. We found fast-onset PCTs to have a significantly different three-dimensional telomere profile, compared with primary B cells of wild-type littermates with and without rcpT(X;11) (P < .0001 and P = .006, respectively). Our data also indicate for primary PCT cells, from the above mouse strain, that the translocation chromosome carrying 11E2 is the only chromosome with telomere lengthening (P = 4 x 10(-16)). This trend is not seen for T(X;11) in primary B cells of control [T38HxBALB/c]N mice with the rcpT(X;11). This finding supports the concept of individual telomere lengthening of chromosomes that are functionally important for the tumorigenic process.

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.
