DD3PCA3 gene expression in cancer and prostatic hyperplasia
Bibliographic record
Abstract
PURPOSE: DD3(PCA3) is a novel gene with characteristics that indicate its potentially valuable role in early identification and diagnosis of malignancy and highly upregulated in transformed cells in PCa. The aim of this work was to validate and analyze, by real-time Reverse Transcription-Polymerase Chain Reaction (RT-PCR), the expression of the DD3(PCA3)gene in a Mexican population, both in intratumoral tissue with PCa and benign prostatic hyperplasia (BPH). METHODS: Human samples from patients with PCa (40 cases) and benign prostatic hyperplasia (40 cases) were analyzed for the mRNA expression of DD3(PCA3)by RT-PCR RESULTS: The GAPDH gene showed better stability with a Pearson correlation of 0.953 (P < 0.007) for the determination of housekeeping gene. DD3(PCA3)gene expression was 29.74 times higher in PCa tissue (P < 0.0001) than in BPH. The gene expression for the PCa and BPH was 1731+/-280 and 58.23+/-9.9 fold, respectively. CONCLUSIONS: Determination of DD3(PCA3)gene expression by RT-PCR could be a potentially tool for the early detection of PCa in clinical specimens.

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.
