Abstract
AbstractThe implication of inflammation in the pathophysiology of several types of cancers has been under intense investigation. Conjugated fatty acids can modulate inflammation and present anticancer effects, promoting cancer cell death. In this paper, we evaluated the efficacy of new conjugated fatty acids isolated from marineOpisthopterus tardoore(Tapra fish) in human breast cancer cell lines MCF7. Linoelaidic acid, a marine fish (O. tardoore) derived unsaturated fatty acids, showed effective anticancer activity against MCF-7. MTT assay revealed a dose-dependent decline in cancer cell viability. It was noteworthy that 5 µM linoelaidic acid decreased the MCF-7 cell viability by 81.82%. Besides that, linoelaidic acid significantly (p < 0.05) increased the level of TNF-α and IL-1ra studied by ELISA. Not only that, linoelaidic acid significantly decreased the reduced glutathione level and increased the oxidized glutathione level in MCF-7 cells indicating the oxidative stress inside the cell. Two different cell staining methods with acridine orange-ethidium bromide and DAPI confirmed that the linoelaidic acid rendered their detrimental effect on cancer cells. To decipher the mode of apoptosis Western blotting was performed in which the expression pattern of several proteins (p53, IL 10, and IL 1ra) established the apoptosis in the studied cell lines after linoelaidic acid exposure. Hence it may be conferred that linoelaidic acid has prompt anticancer activity. So, this drug can be used further for the treatment of cancer.
