Unraveling The Molecular Foundations Behind The Diverged Behaviors Of Mouse Insulin 1 And Insulin 2, Connecting Diabetes Risk With Glucocorticoid Treatment And Chronic Migraine Through The Analysis Of Islet Chemistry, And Capturing Key Posttranslational Modifications All Through The Application Of A Novel Lc-Ims-Ms Workflow, Connor Christopher Long
Select or Award-Winning Individual Scholarship
We display the capabilities of our established liquid chromatography-ion mobility spectrometry-mass spectrometry (LC-IMS-MS) workflow in the investigations of islet chemistry at the sub-single-islet level. We begin by characterizing the structural differences of Ins1 and Ins2 to present novel insights as to why their behaviors diverge. We then examine the effects of the stress hormone corticosterone, the rodent equivalent of human cortisol that is often used as a therapeutic, on pancreatic peptide hormone secretion. We also uncover the molecular connection behind the inverse relationship between type 2 diabetes (T2D) risk and chronic migraine via the neuropeptides CGRP and PACAP. Lastly, we …
