Boswellic acid disables signal transduction of IL-6–STAT-3 in Ehrlich ascites tumor bearing irradiated mice
Bibliographic record
Abstract
Boswellic acid (BA) is known for its ability to trigger apoptosis as well as to inhibit angiogenesis in tumor tissue. In this study, we investigated the effect of BA on the IL-6-STAT-3 signalling pathway in irradiated mice bearing solid tumors of Ehrlich ascites carcinoma (EAC). For this, we administered BA (25 mg·(kg body mass)(-1)·day(-1), by intraperitoneal injection) to mice with EAC, and then exposed them to 4 Gy of gamma radiation. Data analyses of the results revealed a specific impact from BA on IL-6R mRNA and survivin mRNA in EACs and irradiated EAC-bearing mice. Also, significant improvements were observed in the protein expression of JAK-1, P-JAK-1, STAT-3, P-STAT-3, and caspase-3, as well as VEGF and IL-6 levels. We propose that BA interfered with IL-6-STAT-3 signal transduction, thereby preventing the activation of caspase-3 and subsequently triggering the process of apoptosis. However, the alternative angiogenesis pathway, which includes the over-expression of VEGF and which depends on IL-6-STAT-3 signalling, was inhibited by the action of BA. Thus, we recommend that therapeutic strategies for cancer should include treatment with BA.

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.
