Abstract
It has been increasingly appreciated that steroids elicit acute vascular effects through rapid, so-called nongenomic signaling pathways. Though aldosterone, for example, has been demonstrated to mediate rapid vascular effects via both mineralocorticoid receptor-dependent and -independent pathways, the mechanism(s) of this mineralocorticoid receptor-independent effect of aldosterone is yet to be determined. For estrogen, its rapid effects have been reported to be, at least in part, mediated via the 7-transmembrane-spanning, G protein-coupled receptor GPR30. Previous studies have demonstrated common response outcomes in response to both aldosterone and estrogen on GPR30 expression, ie, activation of phosphatidylinositol 3-kinase-dependent contraction and extracellular signal-regulated kinase activation in vascular smooth muscle cells. The present studies were undertaken to test the hypothesis that the rapid response to aldosterone in smooth muscle is dependent on the availability of a GPR30-dependent signaling pathway. These findings not only reconcile differences in the literature for aldosterone response in freshly isolated versus cultured aortic smooth muscle cells but also suggest alternative therapeutic strategies for modulating aldosterone actions on the vasculature in vivo.

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 it
