Growth hormone and cell survival in the neural retina: caspase dependence and independence
Bibliographic record
Abstract
Growth hormone has recently been shown to be expressed in the retinal ganglion cells of embryonic chicks, in which it induces cell survival during neurogenesis. The mechanism of this action has been examined in neural retina explants from 6-day-old and 8-day-old embryos that were incubated for 48 h in 10 M growth hormone, to reduce the number of spontaneous apoptotic cells. This anti-apoptotic action was accompanied by a reduction in caspase-3 expression and, at embryonic day 8, by reduced expression of apoptosis inducing factor-1, which is caspase independent. These actions were specific, as other genes involved in apoptotic signaling (bcl-2, bcl-x, bid and inhibitor of apoptosis protein-1) were unaffected. These results therefore demonstrate caspase-dependent and caspase-independent pathways in growth hormone-induced retinal cell survival.

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.
