A Review of the Expression of Genes Involved in Sex Steroid Hormone Metabolism in Prostate Tissue: A Need for Epigenetic Information
Bibliographic record
Abstract
There is strong clinical and laboratory evidence indicating that sex steroid hormones are important to the development and progression of prostate cancer, yet results from epidemiologic research conflicts. Examining gene expression in the sex steroid hormone pathway may uncover differences between cancerous and non-cancerous prostate tissues, yet our review using a pathway-oriented approach indicates that there is limited consistency across results, with the exception of GSTP1 found in the estrogen pathway, which was under-expressed in cancerous prostate tissue. This agrees with past studies that reported GSTP1 is methylated in prostate cancer. With new cost-effective technology, we can screen for epigenetic markers, like methylation, which can be applied in epidemiological studies. A clearer understanding of gene expression and epigenetic mechanisms in prostate cancer may contribute to improving prevention, diagnosis, and treatment.

How this classification was reachedexpand
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.
