Mr. Jorge Martinez presented research on how yeast cells undergo endocytosis and autophagy in response to glucose availability. The seminar discussed how protein adaptors called arrestins help glucose pass into yeast cells under normal glucose conditions, but the arrestins have nowhere to adhere and the cells begin digesting themselves when glucose is lacking. Experiments with yeast groups that had sufficient or limited glucose access for two hours confirmed that environmental cues like glucose availability affect autophagy processes in the cells. The research contributes to understanding how cellular glucose levels impact diverse biological functions.
