mRNA Destabilizing Factors: Tristetraprolin Expression at the Porcine Maternal–Fetal Interface
Bibliographic record
Abstract
PROBLEM: To evaluate the expression of the tristetraprolin family and their selected targets during porcine pregnancy. METHOD OF STUDY: Using qPCR and Western blot, mRNA and protein levels were compared between endometrium and chorioallantoic membrane (CAM) associated with healthy and impaired conceptuses at gestation day (gd) 20 and gd50, respectively. Immunohistochemistry was performed to determine localization of TIS11 family members at gd20 and 50. RESULTS: Multiple significant differences (P < 0.05) in TIS11 family transcripts were observed in the aforementioned comparisons. GM-CSF was significantly higher in healthy endometrium and CAM from impaired conceptus attachment sites. TNF-α was elevated in CAM as compared to endometrium at gd50, regardless of conceptus health status. Immunohistochemical staining shows TIS11 family expressed in the glandular and luminal epithelium, as well as stromal cells in the uterus. CONCLUSIONS: The shift in the expression of tristetraprolin (TTP) and TIS11D points to a potential role of these genes in regulating spontaneous fetal loss.

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.
