Chromatin condensation and fragmentation caused by CUG-initiated FGF-2 in cardiomyocytes
Bibliographic record
Abstract
Fibroblast growth factor-2 (FGF-2) is a multifunctional factor which is found in 21-25 kDa high molecular weight (HMW), or 16-18 kDa low molecular weight (LMW) forms, resulting from translation initiation from unconventional CUG- or conventional AUG- start sites, respectively. Previous studies have demonstrated that rat HMW- but not LMW-FGF-2, introduced into cardiac myocytes by gene transfer, caused a distinct nuclear phenotype, characterized by condensed chromatin and formation of several DNA 'clumps' inside the nucleus. In the present study we investigated first whether human HMW FGF-2, sharing 82% homology with its rat counterpart at the CUG-initiated extension, was also capable of eliciting the same phenotype as rat HMW FGF-2. Secondly, we investigated whether the mechanism of chromatin condensation and separation caused by HMW FGF-2 engaged an apoptosis-like, mechanism. Finally, we examined whether the HMW FGF-2 induced nuclear phenotype resulted from a mitosis-like mechanism. (Abstract shortened by UMI.)

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
