  • Oleic acid present in olive oil can combat cell death due to excess iron

    Publicado em 14/11/2023 às 12:04 PM

    In 1992, a young child died when his two-year-old brother gave him more than 30 bright, colorful pills. Inside the pills was the metal iron, deadly when ingested in excess. The use of tablets at adequate levels by the children’s mothers characterized dietary supplementation, as iron is essential for human beings, and its deficiency also causes harmful effects on health.

    The research group, coordinated by Professor Marcelo Farina from the Biochemistry department at UFSC, has studied how excess iron causes damage to organisms and how some fat molecules (lipids) protect against injuries caused by iron. In a study conducted in collaboration with American and Spanish researchers, the research group coordinated by Professor Farina discovered that one of the main mechanisms by which excess iron causes damage is through the induction of ferroptosis, a type of cell death that is still poorly understood and characterized by intense oxidation of lipids in cell membranes. The work was funded by CAPES, CNPq, and FAPESC.

    According to the professor, the harmful effects of excess iron do not only occur in severe cases of acute poisoning. “In fact, there is a human disease called hemochromatosis characterized by excess iron in the body due to genetic defects or the need for repeated blood transfusions, which have high levels of this metal”, he explains.

    According to him, scientific evidence supports an association between iron levels and aging and points to iron accumulation in aging-related diseases. Patients with Parkinson’s disease have high iron levels in certain regions of the central nervous system. Among the treatments currently available for individuals with excess iron in the body, phlebotomy (bleeding) and chelating medications stand out, which form complexes with iron and facilitate its elimination.

    The study, which was based on experimental models using the nematode Caenorhabditis elegans, mice and human cell lines, detected a lipid compound called oleic acid, a monounsaturated fatty acid present in abundance in olive oil, as a protective molecule capable of inhibiting ferroptosis. The consequence would be protection against damage induced by iron overload in the three experimental models.

    “The study suggests that nutritional strategies based on the use of monounsaturated fatty acids, such as oleic acid, can mitigate the damage induced by excess iron, which could represent an additional therapeutic strategy”, explains the professor. “Interestingly, oleic acid is part of the Mediterranean diet, which is associated with health and longevity,” reinforces

    Another mechanism uncovered in the study was the involvement of a key protein that determines whether oleic acid can be protective. In this case, the protein PPAR-alpha (peroxisome proliferator-activated receptor-alpha) was considered fundamental to the ability of oleic acid to protect against damage induced by excess iron in cells and nematodes.

    The results of the study were disclosed in a scientific article published in the journal Cell Chemical Biology, which has as its first author researcher Josiane Mann, who was supervised by professor Marcelo Farina during her doctorate in the Postgraduate Program in Neurosciences and is currently a postgraduate fellow -Ph.D. from PPGBQA. The UFSC team included PPGBQA doctoral student Melania Santer and professor Alcir Dafré. The work is also signed by Professor Brent Stockwell (Columbia University, United States), who coordinated the pioneering work that culminated in the discovery of ferroptosis around a decade ago.
