Abstract
OBJECTIVES: To investigate the effect of a seashell protein Haishengsu (HSS), an extract from a shellfish Tegillarca granosa, on cell growth and the expression of apoptosis genes in leukemia K562 cells. METHODS: Cultured K562 cells were treated with HSS at various concentrations (10-40 mg/L). The cell cycle, cell growth and the expression of apoptosis suppressor gene bcl-2 and apoptosis promoting gene bax were evaluated. RESULTS: HSS, 20mg/L, inhibited cell cycle in the G0/G1 and S phases. HSS, 20mg/L, also inhibited the growth of K562 cells over time. Expression of bcl-2 gene in the HSS 20mg/L (58.8%+/-4.7%) and HSS 40 mg/L group (26.6%+/-2.1%) were lower than in the control group (91.0+/-8.7%, P < 0.01). Expression of bax gene in the HSS 20mg/L (77.7+/-3.6%) and 40 mg/L group (90.6+/-3.7%) were higher than in the control group (10.9+/-6.6%, P < 0.01). CONCLUSION: HSS suppresses leukemia K562 cell growth by inhibiting the G0/G1 and S phases of the cell cycle. It also induces apoptosis in these leukemia cells by reducing the expression of apoptosis suppressor gene bcl-2, and increasing the expression of apoptosis promoting gene bax. Further studies are required to investigate the clinical efficacy of HSS in leukemia.

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
