Sodium oleate, also known as oleic acid sodium, is a monounsaturated fatty acid abundant in human adipocytes and other tissues. It acts as an activator of Na+/K+ ATPase. Oleic acid stimulates cell proliferation and migration in highly metastatic cancer cells by enhancing β-oxidation through AMPK activation. Conversely, it inhibits cancer cell growth and survival in low metastatic carcinoma cells, including gastric carcinoma SGC7901 and breast carcinoma MCF-7 cell lines. Furthermore, sodium oleate activates PKC (Protein Kinase C) in hepatocytes.
