(8) Re-feeding starved rats increased the biogenesis of sterols in livers, with highest activity at 6h after the start of food intake.
(9) The observation that peroxisomes of Saccharomyces cerevisiae can be induced by oleic acid has opened the possibility to investigate the biogenesis of these organelles in a biochemically and genetically well characterized organism.
