Transgenic expression and recovery of biologically active recombinant human insulin from <i>Arabidopsis thaliana</i> seeds
Bibliographic record
Abstract
The increased incidence of diabetes, coupled with the introduction of alternative delivery methods that rely on higher doses, is expected to result in a substantial escalation in the demand for affordable insulin in the future. Limitations in the capacity and economics of production will make it difficult for current manufacturing technologies to meet this demand. We have developed a novel expression and recovery technology for the economical manufacture of biopharmaceuticals from oilseeds. Using this technology, recombinant human precursor insulin was expressed in transgenic plants. Plant-derived insulin accumulates to significant levels in transgenic seed (0.13% total seed protein) and can be enzymatically treated in vitro to generate a product with a mass identical to that of the predicted product, DesB(30)-insulin. The biological activity of this product in vivo and in vitro was demonstrated using an insulin tolerance test in mice and phosphorylation assay performed in a mammalian cell culture system, respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
