The yeast vacuole plays a key role in cellular protein metabolism. Under nutrient starvation, a portion of the cytoplasm is non‐selectively sequestered into autophagosomes. Since Ramadan intermittent fasting (RIF) has been associated with reduced caloric intake, it was hypothesized that RIF would alleviate oxidative stress in healthy volunteers. Most of these 18 genes are conserved in mammals, suggesting that the mechanism of autophagosome formation is basically conserved from yeast to mammals. FEBS Lett, 333, 169 - 174.

Autophagy 2008, 4, 740-743. Iowa State University - Cited by 1,992 - Transportation - logistics - mathematical model In Saccharomyces cerevisiae, a membrane sac called the isolation membrane (IM) is generated from the pre-autophagosomal structure (PAS); ultimately, the IM expands to become a mature autophagosome. In the early 1990s, Yoshinori Ohsumi has started his research career as an Assistant Professor of Tokyo University in autophagy with budding yeast Saccharomyces cerevisiae as model system. Macroautophagy (hereafter autophagy) is a major route for transport of intracellular material into lysosomes or vacuoles in almost all eukaryotes (Ohsumi, 2014; Yang and Klionsky, 2010).In autophagy, a membrane cisterna called the isolation membrane (or phagophore) is generated, expands, becomes spherical, and closes to form a double membrane vesicle called the autophagosome.
