Glucosinolates from Seed-Press Cake of <i>Camelina sativa</i> (L.) Crantz Extend Yeast Chronological Lifespan by Modulating Carbon Metabolism and Respiration
Glucosinolates (GSLs) are nitrogen/sulfur-containing glycosides widely present in the order of Brassicales, particularly in the Brassicaceae family. Camelina (<i>Camelina sativa</i> (L.) Crantz) is an oilseed plant belonging to this family. Its seeds, in addition to a distinctive fatty a...

| description | Glucosinolates (GSLs) are nitrogen/sulfur-containing glycosides widely present in the order of Brassicales, particularly in the Brassicaceae family. Camelina (<i>Camelina sativa</i> (L.) Crantz) is an oilseed plant belonging to this family. Its seeds, in addition to a distinctive fatty acid composition, contain three aliphatic GSLs: glucoarabin, glucocamelinin, and homoglucocamelinin. Our study explored the impact of these GSLs purified from Camelina press cake, a by-product of Camelina oil production, on yeast chronological aging, which is the established model for simulating the aging of post-mitotic quiescent mammalian cells. Supplementing yeast cells with GSLs extends the chronological lifespan (CLS) in a dose-dependent manner. This enhancement relies on an improved mitochondrial respiration efficiency, resulting in a drastic decrease of superoxide anion levels and an increase in ATP production. Furthermore, GSL supplementation affects carbon metabolism. In particular, GSLs support the pro-longevity preservation of TCA cycle enzymatic activities and enhanced glycerol catabolism. These changes contribute positively to the phosphorylating respiration and to an increase in trehalose storage: both of which are longevity-promoting prerequisites. |
