Myosin light chain phosphorylation‐dependent modulation of volume‐regulated anion channels in macrovascular endothelium
Bibliographic record
Abstract
The Rho/Rho-associated kinase (ROK) pathway has been shown to modulate volume-regulated anion channels (VRAC) in cultured calf pulmonary artery endothelial (CPAE) cells. Since Rho/ROK can increase myosin light chain phosphorylation, we have now studied the effects of inhibitors of myosin light chain kinase (MLCK) or myosin light chain phosphatase (MLCP) on VRAC in CPAE. Application of ML-9, an MLCK inhibitor, inhibited VRAC, both when applied extracellularly or when dialyzed into the cell. A similar inhibitory effect was obtained by dialyzing the cells with AV25, a specific MLCK inhibitory peptide. Conversely, NIPP1(191-210), an MLCP inhibitory peptide, potentiated the activation of VRAC by a 25% hypotonic stimulus. These data indicate that activation of VRAC is modulated by MLC phosphorylation.

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.
