BIOACTIVITY OF Caulerpa taxifolia (Vahl) Agardh (1817) IN METABOLISM AND VASCULOGENE OF TUMOR CELLS
Bibliographic record
Abstract
Breast cancer is Among many mechanisms, stimulation of angiogenesis leads to increased secretion of vaso-inducing factors and decreased inhibitors. The present study evaluated the interference of Caulerpa taxifolia hydroalcoholic (EHA – 50 μg / mL) and methanolic (EM – 50 μg / mL) extracts in energy metabolism and Angiogenesis of embryos of Gallus gallus domestic L. Rhode Island Red Eggs Red of four lots, were incubated at 37º C, with automatic turning, for the study of energy metabolism and angiogenesis. The groups were distributed and divided into control groups, treated EHA (50 μg / mL) and ME (50 μg / mL), and control enriched with ω-3, with and without tumor. In the 288 hour stage, development was halted. The vessels were quantified and characterized morphologically and the embryos photographed, fixed and processed. The results of energetic metabolism indicated that there was no significant difference between control and normal treated groups, however, animals with EHA and ME induced tumors and those with ω-3 enriched presented a significant response when compared to control (p≤0.05). It was observed that the physical properties and the structural integrity of the bark of the control animals showed formation abnormalities: rough, rough and soft bark. Morphometric parameters were not significant between groups (p≤0.05). In relation to vasculogenesis and angiogenesis there was a significant reduction between normal and tumorous groups. The vessels showed a slight reduction of the caliber when compared to the control group (p≤0.05). The microscopic appearance of the amniotic membrane of the organisms treated with EHA and ME from the normal and tumor groups maintained the morphology preserved throughout the treatment. Cardiovascular tissue from tumor-containing embryos had bleeding points and a congestion in the lumen of the vessel, perhaps due to the presence of malignant cells. Microscopy of the medulla was preserved. In the control embryos it was poorly conserved, with congested vessels in the mantle region, possibly due to interference of the tumor in the analyzed tissue. These biocomposites also had an anisculogenic and antiangiogenic effect, without compromising the macroscopic and microscopic anatomy of the organisms treated during the embryonic development. In view of the present, it is concluded that the compounds present in extracts of Caulerpa taxifolia can be considered a potential antitumor agent of marine origin, which may act on the intrinsic mechanisms related to the extracellular matrix, stabilizing and remodeling vascular structure and the capacity of induction of neovasculogenesis.

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.
