GLA supplementation regulates PHD2 mediated hypoxia and mitochondrial apoptosis in DMBA induced mammary gland carcinoma.

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 1H 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 through1H NMR studies. The immunoblotting and qRT-PCR studies accomplished that gamma linolenic acid 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. Afterwards, it was concluded that GLA causes mitochondrial death of cells along with curtailment of hypoxic microenvironment and mediates cholinergic anti-inflammatory activity.
