Effect of paracetamol in the proliferation of glioblastoma cell line: the role of apoptosis, cox-2 and cyclin b expressions
Bibliographic record
Abstract
AIM: To investigate the relationship between paracetamol and expression levels of cyclooxygenase-2, cyclin B, cell viability and apoptosis in glioblastoma cell line. MATERIAL AND METHODS: The A172 glioblastoma cells were treated with different concentrations of paracetamol and phosphate buffer saline as a vehicle for 24, 48, and 72 hours. Cell viability was detected by MTT. Bax, procaspase 3, COX-2 and Cyclin B expressions were detected using Western blotting. RESULTS: A paracetamol treatment of 0.5 mg/mL for 24, 48, and 72 hours led to a 14%, 31%, and 37% decrease in cell viability. The expression of COX-2 and cyclin B levels decreased by 36% and 52% respectively, after treatment with 0.5 mg/mL paracetamol. Treatment with 0.5 mg/mL and 1 mg/mL paracetamol significantly induced the expression of cleaved caspase 3, procaspase 3 and Bax proteins compared to the control group (60%, 40%, 21%, %100, 18%, 17%, respectively). CONCLUSION: The results of our study showed that paracetamol has antitumoral effects on glioblastoma cells and this activity was induced by different signaling pathways.

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.
