Atg11 And Atg9 Interaction In Selective Autophagy, Chimi Dolker Sherpa

Master's Theses and Doctoral Dissertations

Selective autophagy, induced by cellular stresses, degrades/recycles a specific cargo. Ithelps prevent diseases like Parkinson’s, Huntington's, cancer, and bacterial infections. It involves the formation of an autophagosome, a double-membrane vesicle that takes the cargo to the vacuole/lysosome for degradation. Atg11, the central organizer of selective autophagy, acts as a scaffold protein, interacting with Atg9, Atg1 and other Atg proteins. Our research focuses on finding mutations in Atg11 that specifically disrupt its interaction with Atg9 without affecting its dimerization or interaction with Atg1. We targeted residues 455-535 of Atg11 as a putative Atg9 interaction site, performing mutagenesis on four key residues …

The Investigation Of The Antimicrobial And Biofilm-Disrupting Properties Of Synthesized Hemibastadin Derivatives, Antonio Harvey, Andrew A. Yeagley

Longwood Senior Thesis Proposal

We want to investigate structural changes to the core hemibastadin structure while attempting to make these derivatives biologically safer. Since these modifications have never been done before, we will need to design a synthesis of these new molecules. Due to the nature of the molecules (dimers), a divergent synthesis that allows for the creation of both halves simultaneously seems most appropriate. A successful synthesis of these compounds will allow us to further investigate these derivatives for their antimicrobial and biofilm-disrupting properties.
