Stress-Dependent Regulation Of A Major Node Of The Insulin-Like Peptide Network That Modulates Survival, Rashmi Chandra Jan 2019

Stress-Dependent Regulation Of A Major Node Of The Insulin-Like Peptide Network That Modulates Survival, Rashmi Chandra

Wayne State University Dissertations

Chronic stress disrupts insulin signaling, predisposing human populations to diabetes, cardiovascular disease, Alzheimer’s Disease, and other metabolic and neurological disorders, including post-traumatic disorders (PTSD). Thus, efficient recovery from stress optimizes survival. However, stress recovery in humans is difficult to study, but is much easier to dissect in model organisms. The worm genetic model Caenorhabditis elegans can switch between stressed and non-stressed states, and this switch is largely regulated by insulin signaling. Previously, the Alcedo lab proposed that insulin-like peptides (ILPs), which exist as multiple members of a protein family in both C. elegans and humans, implements a combinatorial coding strategy …
