Cytoskeletal remodeling and regulation of cell fate in the hypertensive neonatal pulmonary artery in response to stress
Bibliographic record
Abstract
Neonatal pulmonary hypertension (PHN) is a lethal progressive disease that occurs in prenatal circulatory transition. Mechanical wall strain caused by cardiac pulsation integrates with hypoxia to generate rapidly progressive myocyte cytoskeleton disassembly and failure to exert force generation. The physiological responses to such an interaction have not been investigated. The persistent phenotype does not respond to traditional vasodilator therapy; hence, there is a need for new treatment strategies to improve the morbidity and mortality outcomes. We reviewed the current research methods, models, and markers of persistent PHN relevant to oxidative and nitrosative stress as well as cell fate commitment, with an emphasis on apoptosis and proliferation. We surveyed potential investigations into the role of senescence in neonatal PHN cell fate decision programming during vasodilator treatment and suggested putative drug targets to improve clinical outcomes. We identified important signaling intermediates of senescence and cell cycle entry regulation in hypertensive pulmonary arterial tissues.

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.
