Microinjection of <I>myo</I>-Inositol(1,4,5)Trisphosphate and Other Calcium-Mobilizing Agents Into Intact Adherent Cells<U>
Bibliographic record
Abstract
Many receptor tyrosine kinases and seven-transmembrane receptors are directly coupled or coupled via G proteins, respectively, to the activation of phosphoinositidase Cs. These enzymes catalyze the hydrolysis of phosphatidylinositol 4,5-bisphosphate to produce the second messengers, myo-inositol(1,4,5)trisphosphate [Ins(1,4,5)P(3)] and diacylglycerol. Ins(1,4,5)P(3) interacts with a specific receptor that is a ligand-gated channel that allows mobilization of non-mitochondrial intracellular calcium (Ca(2+)) stores. Because Ins(1,4,5)P(3) is plasma membrane impermeant, this phenomenon was first demonstrated in permeabilized pancreatic acinar cells, and all subsequent studies in cells have involved introduction of Ins(1,4,5)P(3) by rendering a cell population permeable (3), using microinjection techniques, or by the presentation of chemically modified membrane-permeable Ins(1,4,5)P(3) analogs, such as photolabile "caged Ins(1,4,5)P(3)". An alternative approach involves disruption of the plasma membrane and preparation of microsomes from the intracellular vesicular Ca(2+) stores; however, microsomal preparations exhibit a loss of Ins(1,4,5)P(3) responsiveness compared to permeabilized and intact cells.

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; a candidate call from one teacher head, not a consensus.
