Morphologic Responses of Endothelium to Shear Stress: Reorganization of the Adherens Junction
Bibliographic record
Abstract
Shear stresses induce marked morphologic responses from endothelium which include alterations to cell shape and orientation and changes to cytoskeletal organization. These morphologic changes necessitate remodeling of cell-cell adhesion complexes that are important to control of endothelial cell physiology. Reorganization of endothelial adherens junctions has been characterized, and there are some data that pertain to the signaling pathways that regulate this reorganization. Shear-induced activation of Src, mitogen-activated protein (MAP) kinase (ERK1/2 and p38), and PI 3'-kinase pathways are important candidate pathways, and there is evidence for a role for the Rho GTPases. Very little is known concerning shear-dependence of other junctional complexes, but available data indicates a high degree of shear sensitivity. Given the continuous changes in hemodynamics which occur physiologically in vivo, sensitivity of endothelial cell-cell adhesion complexes to shear will likely prove important to vascular pathophysiology.

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.
