GnRH agonist (buserelin)-induced in vitro apoptosis in bovine endometrium
Bibliographic record
Abstract
Singh, R., Pretheeban, T. and Rajamahendran, R. 2011. GnRH agonist (buserelin)-induced in vitro apoptosis in bovine endometrium. Can. J. Anim. Sci. 91: 265-273. Apoptosis is a vital physiological process. The local modulatory role of the GnRH, GnRH-R system in uterine physiology is not clear. We investigated GnRH agonist (buserelin)-induced apoptosis in bovine endometrium. Reproductive tracts were collected from a local abattoir. The endometrial explants were sliced into smaller pieces, cultured for 20 h and then treated (6 h) with buserelin (0, 200, 500, 1000 ng mL-1), the GnRH antagonist-antide (500 ng mL-1) and antide+buserelin (500+200 ng mL-1), and stored at -80°C for RNA extraction. Two micrograms of total RNA was subjected to reverse transcription-polymerase chain reaction using gene-specific primers. Subsequently, endometrial epithelial cells were isolated from the follicular and luteal phase uteri, cultured for 48 h, characterized and treated with buserelin (200 ng mL-1), antide (500 ng mL-1), and antide+buserelin (500+200 ng mL-1) for 6 h. The cells were stained with acridine orange-ethidium bromide and visualized and counted under a fluorescent microscope. Buserelin up-regulated BAX (200 ng mL-1) and CASPASE3 mRNA (200 and 500 ng mL-1) and induced apoptosis (200 ng mL-1) at the cellular level in the follicular phase endometrium. GnRH appears to regulate uterine homeostasis in bovine endometrium at the transcriptional and cellular levels.

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; both teacher heads agree on what is shown here.
