Abstract
Endometriosis is hypothesized to result from retrograde menstruation where cell debris including endometrial stromal cells (ESCs) travel through the fallopian tubes. This chronic inflammatory disease is characterized by inflammatory and fibrotic endometrial tissue. We have previously observed reduced expression of the anti-inflammatory factor SERPINA1 in endometriosis-like lesions in a mouse model implanted with human ESCs. Additionally, pro-inflammatory factors present in peritoneal hemorrhage exacerbated inflammation in these grafts, partly through prostaglandin (PG) E2 and thrombin. However, it remains unclear whether the reduction of SERPINA1, in combination with PGE2 and thrombin, synergistically influences the expression of inflammatory factors in endometriosis lesions and the underlying mechanisms. We analyzed RNA sequencing data from ESCs treated with SERPINA1 siRNA and PGE2/thrombin, comparing them to data sets derived from ESCs subjected to either SERPINA1 knockdown or PGE2/thrombin treatment. Comparative analysis identified 49 transcripts that were upregulated under both conditions and enriched for transcription regulatory genes, including SNAI1, HDAC5, PBX1, SOX4, EPAS1, LHX9, and MAFK. Silencing SNAI1, HDAC5, SOX4, EPAS1, or LHX9 suppressed IL6, CXCL8, and IL1B expression, which had been upregulated by SERPINA1 siRNA and PGE2/thrombin. Among these genes, LHX9 expression was significantly elevated in ectopic lesions, predominantly localized to stromal and glandular epithelial cells, with more pronounced expression during the secretory phase. LHX9 levels were also increased in endometriotic lesions compared to the normal endometrium. In conclusion, reduced SERPINA1 expression in ectopic ESCs, combined with PGE2/thrombin, induces inflammatory cytokine expression linked to LHX9. Pharmacological targeting of LHX9 may present a promising therapeutic strategy for mitigating chronic inflammation in endometriotic lesions.

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 it
