Abstract

fetched live from OpenAlex

PROBLEM: Tumor necrosis factor-alpha (TNF-alpha) is secreted mainly during the menstrual phase and has been suggested to play a role in induction of apoptosis in endometrial cells and menstrual shedding. TNF-alpha receptor type 2 (TNF-RII) is believed to play a central role in TNFalpha-mediated cytotoxic, mitogenic, anti-proliferative and apoptotic effects. The aim of this study was to assess whether TNF-RII maybe expressed differentially in the endometrium of women with different degrees of endometriosis. METHOD OF STUDY: TNF-RII expression in the endometrial tissue of women with and without endometriosis was investigated by immunohistochemical techniques and in situ hybridization. RESULTS: In histological sections, we observed TNF-RII mRNA and the corresponding protein localized mainly in endometrial glandular cells, with only very faint immunostaining in the surrounding stromal cells. Statistical analysis of our data showed a significant decrease in protein and mRNA expression of TNF-RII in endometrial glandular cells of patients with stages I and II endometriosis compared to normal subjects. TNF-RII expression was also found to decrease significantly in the secretory phase of the menstrual cycle in women with early endometriosis stages (I and II). CONCLUSIONS: In view of the relevant role of TNF-RII in the modulation of the inflammatory and the proapoptotic effects of TNFalpha, deficient expression of TNF-RII mRNA in the endometrium of women at the earliest stages of endometriosis may play a significant role in the pathophysiology of this disease.

Not 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.
