15 new groups of molecules to fight against aging and protect our cells; one step closer to staying healthy longer, new study shows Français
A Concordia researcher, supported by Idunn Technologies, discovers new natural compounds that could promote longevity in health and reduce the incidence of associated diseases
MONTREAL, Sept. 9, 2020 /CNW/ - The recent pandemic has highlighted the importance of staying healthy so that you can better fight an infection or disease, if necessary. A Concordia University researcher has discovered 15 new plant extracts that help fight, not against infection, but against aging. These natural molecules could help prevent all the diseases associated with aging, not one at a time, but all at the same time. It is therefore a question of reducing the incidence of common ailments such as osteoarthritis, diabetes, cancer, heart disease, Parkinson's and Alzheimer's disease. This approach has already been called "the ultimate preventive medicine" in the prestigious journal, Science.
Vladimir Titorenko, professor of biology at the Faculty of Arts and Sciences at Concordia, has been collaborating since 2013 with Éric Simard, president of the company, Idunn Technologies, to discover new anti-aging molecules. This work has just been published in the scientific journal, Oncotarget. The TransBIOTech research center and the Cégep de Lévis-Lauzon also participated in these studies.
The recently published results were obtained from specific plant extracts, already recognized for various health benefits. Professor Titorenko's team identified the new anti-aging molecules from a long list of extracts from different parts of the plants studied. The new positive extracts (PE for "plant extract") are numbered as follows: PE26 (Serenoa repens), PE39 (Hypericum perforatum), PE42 (Ilex paraguariensis), PE47 (Ocimum tenuiflorum), PE59 (Solidago virgaurea), PE64 (Citrus sinensis ), PE68 (Humulus lupulus), PE69 (Vitis vinifera), PE72 (Andrographis paniculata), PE75 (Hydrastis canadensis), PE77 (Trigonella foenumgraecum), PE78 (Berberis vulgaris), PE79 (Crataegus monogyna), PE81 (Taraxacum erythrospermum) and PE83 (Ilex paraguariensis).
"We now have a large number of anti-aging plant extracts that may reduce the incidence or progression of age-related diseases in humans," said Dr. Vladimir Titorenko. This researcher devotes his efforts to understanding the molecular mechanisms that allow cells to resist aging.
Dr. Titorenko states that "With the aging of the population, the possibility of keeping people healthy longer constitutes a major advance which could have repercussions, not just in economic terms, but for the quality of life of the population and the capacity of the health care system in general."
The results of this research have clearly demonstrated that the beneficial effects observed on longevity are linked to the slowing of aging in yeast cells. "The identification of these new modulators could allow the development of new specialized products for healthy aging." explains Professor Titorenko.
A Quebec company, Idunn Technologies, is working to develop a large number of applications of these research results for human health. Éric Simard is the co-editor of the article, CEO of Idunn Technologies and author of 4 books on healthy longevity (www.esimard.com). He explains that the company decided to market the fruits of this research by focusing on the optimization of natural products targeting the main health problems related to aging. These more effective products are marketed under the Vitoli brand (www.vitoli.ca).
The results presented also include analyses of the metabolic activity of mitochondria, the oxidation of membrane lipids, as well as the oxidation of proteins, DNA from mitochondria, and DNA from the cell nucleus. These anti-aging extracts, also called geroprotective or caloric restriction mimetics, increase the resistance of cells to oxidative stress and temperature. Improved cellular functioning reduces damage to cells while increasing their resistance to difficult situations. "Reduce wear and increase maintenance and cellular resistance; that's the secret to health longevity." concluded Dr. Simard.
This study was supported by a joint ARD-CRD (Applied Research and Development - Cooperative Research and Development) grant from Canada's Natural Sciences and Engineering Research Council (NSERC). The work was also funded by the Concordia University Research Chairs Fund, a Concordia University Graduate Scholarship, and a Concordia University Excellence Scholarship.
