Abstract
Several studies have shown that the levels of caspase-3 are upregulated under different conditions of apoptosis. Previously, we have shown that activation of T cells through the TCR leads to the upregulation of caspase-3 levels. These findings highlight the importance of regulating the expression of caspase-3 in order to prevent premature cell death. To better understand the regulation of the caspase-3 gene, a portion of the 5'- untranslated region was cloned, sequenced, and characterized. The segment of the 5'-flanking region of the caspase-3 gene was also cloned upstream of a luciferase reporter gene, demonstrating that this fragment contains promoter activity. Higher luciferase expression was found with several of the promoter deletion constructs in Jurkat T cells but not the mouse Neuro-2A neuroblastoma cell line, suggesting the presence of a T-cell-specific regulated region. The importance of these sequences is further supported by the genomic organization of the human and mouse caspase-3 promoter regions. These findings demonstrated that the -2245/+14 region of the caspase-3 promoter shows constitutive levels of expression, and that several regions of the promoter play a role in basal regulation. Finally, some of the conserved transcription factor binding sites identified between the human and mouse promoters appear to play an important role in lymphoid cells.

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
