Interaction of Carp Growth Hormone-Releasing Factor and Somatostatin on in vitro Release of Growth Hormone in Rainbow Trout (Oncorhynchus mykiss)
Bibliographic record
Abstract
Possible antagonism between somatostatin (SS) and carp growth hormone-releasing factor (GRF) on growth hormone (GH) secretion was examined by radioimmunoassay in a dispersed rainbow trout pituitary cell culture system. SS (3 nM) significantly antagonized carp GRF(1-29; 1 nM, 10 nM)-induced GH secretion. The slope of the dose-response curve for carp GRF(1-29) with SS was statistically different from that of carp GRF(1-29) alone (p less than 0.05) suggesting a noncompetitive antagonism of SS to carp GRF. The carp GRF(1-29) was also indicated to be a noncompetitive antagonist to SS (p = 0.056). Carp GRF(1-29; 100 nM) was unable to restore the inhibitory effect of SS on GH release after pre-exposure of SS (30 nM) to the pituitary cells. We conclude that SS antagonizes carp GRF on GH release at the pituitary level in rainbow trout and this antagonism is noncompetitive. SS has a postantagonism to carp GRF which may implicate some important physiological adaptations in teleosts.

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.
