Directed Evolution Of Macrocyclic Peptides For Inhibition Of Autophagy, Joshua Gray
Directed Evolution Of Macrocyclic Peptides For Inhibition Of Autophagy, Joshua Gray
Dissertations & Theses (Open Access)
In recent decades it has become increasingly clear that induction of autophagy plays an important role in the development of treatment resistance and dormancy in many cancer types. Chloroquine (CQ) and hydroxychloroquine (HCQ), two autophagy inhibitors in clinical trials, suffer from poor pharmacokinetics and high toxicity at therapeutic dosages. This has prompted intense interest in the development of targeted autophagy inhibitors to re-sensitize disease to treatment with minimal impact on normal tissue. We utilized Scanning Unnatural Protease Resistant (SUPR) mRNA display to develop macrocyclic peptides targeting the autophagy protein LC3. The resulting peptides bound LC3A and LC3B—two essential components of …

Orthopedic surgeries have continued to increase, but the material of choice remains constant: titanium. Titanium has become the benchmark implant material due to its durability and non-immunogenic properties. However, while high rates of success are correlated with joint replacement surgery, certain patients with predisposed diseases such as diabetes or arthritis may have increased complications.1 This can be due to lack of osseointegration due to decreased bone formation and mineralization,2 which will lead to increased rates of infection or aseptic loosening of the implant from the bone. 3 Current methods to alleviate these complications include invasive revisional surgeries, which …
