Role of Insulin in Glucose-Stimulated Insulin Secretion in Beta Cells
Bibliographic record
Abstract
Diabetes is on the increase worldwide and greater than 90% are type 2. There are two features to type 2 diabetes: muscle, fat and liver tissues are insulin resistant and beta cells lose the ability to secrete insulin. Prior to developing diabetes, however, insulin resistant individuals lose the first-phase insulin secretion response. Transgenic mice lacking insulin receptors in their beta cells have no first-phase response. Primary cultures of mouse islets pre-exposed to anti-insulin do not exhibit a first-phase insulin secretion response. That is, beta cells, like muscle, fat, and liver, are an insulin sensitive tissue and in the presence of insulin resistance (type 2 diabetes), in the absence of insulin receptors (transgenic mice lacking beta cell insulin receptors), or in the absence of constitutively secreted insulin (anti-insulin treatment), beta cells are unable to respond properly to post-prandial glucose. The purpose of this report is to review our understanding of the glucose-stimulus response and of insulin signaling, and to suggest why the latter may be necessary for the former to proceed.

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.
