Functional analysis of promoter variants in <i>KU70</i> and their role in cancer susceptibility
Bibliographic record
Abstract
KU70 is involved in the DNA double-strand break repair pathway, which plays a critical role in maintaining genomic stability and preventing cancer. Genetic variation within the KU70 gene has been shown to be associated with increased risk of several types of cancers including breast cancer. Here, we used gene reporter and gel shift assays combined with site-directed mutagenesis to characterize genetic variation within the KU70 proximal promoter region and investigate the putative functional role of regulatory variation and altered KU70 expression in modulating an individual's susceptibility to disease. We show that the variant rs2267437C>G significantly influences KU70 transcriptional activity in an allele- specific manner and alters DNA-protein complex formation in breast cancer cell lines. Our data provide a possible molecular explanation for the associations observed between the KU70 regulatory variant rs2267437 and breast cancer risk.

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.
