1141526807 Expression of inducible microsomal prostaglandin E synthase in local endometriosis lesions
Bibliographic record
Abstract
Recently, an inducible microsomal human prostaglandin E synthase (mPGES) was identified. This enzyme converts the cyclooxygenase (COX) product prostaglandin (PG) H 2 to PGE 2 , an eicosanoid that has been linked to carcinogenesis. Increased amounts of PGE 2 have been observed in many tumor types including colorectal adenomas and cancers. We have already reported increased expression of COX‐2 mRNA in local lesions of endometriosis. To further elucidate the mechanism responsible for increased levels of PGE 2 in endometriosis, we investigated the expression of mPGES. Formalin fixed and paraffin embedded 15 samples were examined with immunohistochemistry. Immunostaining was carried out with a rabbit mPGES‐1 anti‐human polyclonal antiboby. In selected cases, expression of mPGES mRNA was examined by RT‐PCR using total RNA extracted from frozen samples. Immunohistochemistry revealed increased mPGES immunoreactivity in endometriosis samples compared with eutopic endometria. Immunoreactivity of mPGES was observed in both epithelia and stromal or inflammatory cells. Increased expression of mPGES‐1 mRNA was detected in most of endometriosis samples. Taken together, our results suggested that overexpression of mPGES in addition to COX‐2 contributes to possible increased PGE 2 production in endometriosis patients.

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.
