BIOACTIVITY OF Caulerpa taxifolia (Vahl) Agardh (1817) IN METABOLISM AND VASCULOGENE OF TUMOR CELLS
Notice bibliographique
Résumé
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.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
