The aim of the present study is to evaluate the effect of gamma linolenic acid (GLA) on mitochondrial mediated death apoptosis, hypoxic microenvironment and cholinergic anti-inflammatory pathway against 7, 12-dimethylbenz (a) anthracene (DMBA) induced mammary gland carcinoma. The effects of GLA were evaluated morphologically and biochemically against DMBA induced mammary gland carcinoma. The metabolic study was done for evaluation of biomarkers using H NMR. The present study was also verified through immunoblotting and qRT-PCR studies for the evaluation of various pathways. GLA treatment has a delineate implementation upon morphology of the tissues when evaluated through carmine staining, hematoxyline and eosin staining and scanning electron microscopy. GLA also demarked a commendatory proclamation of the fifteen key serum metabolites analogous with amino acid metabolism and fatty acid metabolism when recognized throughH NMR studies. The immunoblotting and qRT-PCR studies accomplished that GLA mediated mitochondrial death apoptosis, curtail hypoxic microenvironment along with hindrance of de novo fatty acid synthesis and also mediate the cholinergic anti-inflammatory pathway to proclaim its anticancer effects.
本研究旨在评估γ-亚麻酸(GLA)对线粒体介导的细胞凋亡、缺氧微环境和胆碱能抗炎途径对 7,12-二甲基苯并(a)蒽(DMBA)诱导的乳腺癌的影响。通过形态学和生物化学方法评估 GLA 对 DMBA 诱导的乳腺癌的作用。采用 H NMR 进行代谢研究,以评估生物标志物。本研究还通过免疫印迹和 qRT-PCR 研究进行了验证,以评估各种途径。通过胭脂红染色、苏木精和伊红染色和扫描电子显微镜评估组织形态时,GLA 治疗对组织形态有明确的影响。通过 H NMR 研究还发现,GLA 还标记了与氨基酸代谢和脂肪酸代谢相似的十五个关键血清代谢物,这表明 GLA 介导的线粒体细胞凋亡、减少缺氧微环境以及抑制从头脂肪酸合成,从而发挥其抗癌作用。
