Antiproliferation Effect of Commercially Brewed Coffees on Human Ovarian Cancer Cells In Vitro
Bibliographic record
Abstract
Numerous scientific studies have examined the relationship between coffee consumption and an array of medical conditions, including cancer, and yet the direct effect of commercially brewed coffee on cancer cells has not been evaluated. The purpose of this study was to evaluate the antiproliferation effect of 4 different regular and decaffeinated coffee brews and 3 of coffee's bioactive ingredients-caffeine, chlorogenic acids, and caffeic acid-on 2 human ovarian cancer cell lines alone and in combination with cisplatin (CDDP). Antiproliferation IC(50) for Brand A regular and decaffeinated coffee on A2780 cells was 1:70.79 ± 5.66 and 1:55.68 ± 2.00 dilution (vol/vol) in tissue culture medium (mean ± standard error of the mean; N = 12), respectively, and slightly lower on A2780CP70 cells. Three other brands showed lower antiproliferation activity. Antiproliferation IC(50) concentrations of chlorogenic acids and caffeic acid are many folds lower than caffeine. In combination with CDDP, both Brand A coffee brews, and the 3 bioactive compounds, showed additive antiproliferation effect on both cancer cell lines. Flow cytometry analysis showed that coffee treatment induced apoptosis of A2780 and A2780CP70 cells. To our knowledge, this is the first report showing the antiproliferation activity and the additive effect with CDDP of commercially prepared coffee brews on human cancer cell lines.

How this classification was reachedexpand
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.
