Non-coding <i>NFKBIZ</i> 3′ UTR mutations promote cell growth and resistance to targeted therapeutics in diffuse large B-cell lymphoma
Bibliographic record
Abstract
Abstract Amplifications and non-coding 3′ UTR mutations affecting NFKBIZ have been identified as recurrent genetic events in diffuse large B-cell lymphoma (DLBCL). We confirm the prevalence and pattern of NFKBIZ 3′ UTR mutations in independent cohorts and determine they are enriched in the ABC subtype as well as the recently described novel BN2/C1/NOTCH2 classes of DLBCL. Presently, the effects of and mechanism by which non-coding mutations can act as cancer drivers has been relatively unexplored. Here, we provide a functional characterization of these non-coding NFKBIZ 3′ UTR mutations. We demonstrate that the resulting elevated expression of IκB-ζ confers growth advantage in DLBCL cell lines and primary germinal center B-cells as well as nominate novel IκB-ζ target genes with potential therapeutic implications. The limited responses to targeted treatments in DLBCL, particularly those targeting the NF-κB axis, led us to investigate and confirm that NFKBIZ 3′ UTR mutations affect response to therapeutics and suggest it may be a useful predictive biomarker. Statement of Significance Through functional characterization we reveal that non-coding NFKBIZ 3′ UTR mutations are a common driver in DLBCL, and mutation status may be a relevant biomarker to predict poor response to therapeutics targeting the NF-κB pathway.

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.
