Abstract

fetched live from OpenAlex

Les forces mécaniques dirigeant la valvulogénèse sont mal connues. Chez le poisson zèbre, le flux induit l’expression du facteur de transcription klf2a de façon endothéliale spécifique afin d’initier ce processus. Nous nous sommes intéressés aux mécanismes moléculaires activés par le flux et aboutissant à la formation des valves cardiaques. En altérant et modifiant le pattern fluidique, nous avons observé le rôle des forces engendrées par le flux pour le contrôle de l’expression de klf2a ainsi que du nombre de cellules endocardiques. Nous avons ensuite regardé les divers mécanosenseurs pouvant intervenir lors de ce processus. Ainsi nous avons mis à jour la présence de cils dans l’endocarde et fait la relation entre les canaux membranaires TRPP2 et TRPV4, la présence de calcium intracellulaire dans les cellules endocardiques et la voie moléculaire PKC-PKD2-HDAC5, composants nécessaires à l’expression du gène klf2a en réponse au flux. Ces données nous permettent de suggérer le rôle de TRPP2, TRPV4 et la voie moléculaire récemment découverte, PKC-PKD2-HDAC5 dans la formation valvulaire dépendante de klf2a.

Full frame distilled prediction

Teacher imitation

Not 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.
