Autophagy:
Yeast is basically the MVP of lab organisms. It’s helped scientists claim five Nobel Prizes in the 21st century (2001, 2006, 2009, 2013 and 2016). Yoshinori Ohsumi, the most recent prizewinner, used baker’s yeast to identify genes crucial in autophagy, the process by which cells recycle their components. Diseases like Parkinson’s, Type 2 diabetes and cancer have been linked to disruptions in this cellular recycling process. The autophagy machinery in yeast cells is similar to that in human cells, and Ohsumi’s work, which began in the 1990s, gives scientists new targets for possible treatments.
