Jatropha-6(17),11<i>E</i>-diene class derivatives induce apoptosis effects in OVCAR-3 and Caov-4 ovarian cancer cell lines via a mitochondrial pathway
Bibliographic record
Abstract
We investigated the molecular mechanism of apoptosis induced by novel jatropha-6(17),11E-diene class derivatives, compounds A, B, and C that were extracted from Euphorbia osyridea Boiss, in the ovarian cancer cell lines Caov-4 and OVCAR-3. The OVCAR-3 and Caov-4 cell lines were treated with different concentrations of these compounds. Cytotoxicity was evaluated using MTT, clonogenic survival assay, and flow cytometry assays. The production of reactive oxygen species (ROS), mitochondrial membrane potential (ΔΨm), and the activity of caspase 3 and 9 were evaluated. Compounds A, B, and C reduced cell viability in a dose-dependent manner (P < 0.05). The IC50 values were calculated as 46.27 ± 3.86, and 38.81 ± 3.30 μmol/L for compound A, 36.48 ± 3.18 and 42.59 ± 4.50 μmol/L for compound B, and 85.86 ± 6.75 and 75.65 ± 2.56 μmol/L for compound C against the Caov-4 and OVCAR-3 cell lines, respectively. Apoptosis evaluation showed that jatrophane derivatives increase both early and late apoptosis (P < 0.01). These compounds also increased ROS generation, ΔΨm, and the activity of caspase 3 and 9 in the treated cells. These results showed that compounds A and B have significant inhibitory effects on OVCAR-3 and Caov-4 proliferation and induction of apoptosis.

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.
