Molecular Cloning of the Human Kallikrein 15 Gene (KLK15)
Bibliographic record
Abstract
Kallikreins are a subgroup of serine proteases with diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis. By using molecular cloning techniques, we identified a new human kallikrein gene, tentatively named KLK15 (for kallikrein 15 gene). This new gene maps to chromosome 19q13.4 and is located between the KLK1 and KLK3 genes. KLK15 is formed of five coding exons and four introns, and shows structural similarity to other kallikreins and kallikrein-like genes. KLK15 has three alternatively spliced forms and is primarily expressed in the thyroid gland and to a lower extent in the prostate, salivary, and adrenal glands and in the colon testis and kidney. Our preliminary results indicate that the expression of KLK15 is up-regulated by steroid hormones in the LNCaP prostate cancer cell line. The KLK15 gene is also up-regulated, at the mRNA level, in prostate cancer in comparison to normal prostatic tissue. KLK15 up-regulation was found to be associated with more aggressive forms of prostate cancer. This newly discovered gene has the potential of being used as a diagnostic and/or prognostic marker for prostate cancer.

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.
