The Spy1/RINGO Family Represents a Novel Mechanism Regulating Mammary Growth and Tumorigenesis
Bibliographic record
Abstract
Spy1A is a unique cell cycle activator known to mediate cell cycle progression and override the DNA damage response. This study focused on determining the role of this protein on postnatal mammary gland morphogenesis and neoplasia. Herein, we show that Spy1A levels are tightly regulated during mammary gland development and that ectopic expression stimulates precocious development and results in disrupted morphology of the gland. This follows the same trend as the oncogene c-Myc, and we show that Spy1A expression is regulated downstream of c-Myc signaling. Importantly, we show that overexpression of Spy1A accelerates tumorigenesis in vivo. Collectively, this work is the first report that the Spy1/RINGO family of proteins may play an essential role in regulating both normal and abnormal growth processes in the breast.

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.
