Trace Amine-Associated Receptor 1 Activation Regulates Glucose-Dependent
Trace amine-associated receptor 1 activation regulates glucose-dependent insulin secretion in pancreatic beta cells in vitro by ©Arun Kumar A thesis submitted to the School of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science Department of Biochemistry, Faculty of Science Memorial University of Newfoundland FEBRUARY 2021 St. John’s, Newfoundland and Labrador i Abstract Trace amines are a group of endogenous monoamines which exert their action through a family of G protein-coupled receptors known as trace amine-associated receptors (TAARs). TAAR1 has been reported to regulate insulin secretion from pancreatic beta cells in vitro and in vivo. This study investigates the mechanism(s) by which TAAR1 regulates insulin secretion. The insulin secreting rat INS-1E -cell line was used for the study. Cells were pre-starved (30 minutes) and then incubated with varying concentrations of glucose (2.5 – 20 mM) or KCl (3.6 – 60 mM) for 2 hours in the absence or presence of various concentrations of the selective TAAR1 agonist RO5256390. Secreted insulin per well was quantified using ELISA and normalized to the total protein content of individual cultures. RO5256390 significantly (P < 0.0001) increased glucose- stimulated insulin secretion in a dose-dependent manner, with no effect on KCl-stimulated insulin secretion. Affymetrix-microarray data analysis identified genes (Gnas, Gng7, Gngt1, Gria2, Cacna1e, Kcnj8, and Kcnj11) whose expression was associated with changes in TAAR1 in response to changes in insulin secretion in pancreatic beta cell function. The identified potential links to TAAR1 supports the regulation of glucose-stimulated insulin secretion through KATP ion channels. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

During the past decade, evidence has accumulated for important and distinct roles of Celsr1–3 in planar cell polarity (PCP) and brain development and maintenance. Although the role of Celsr in PCP is conserved from flies to mammals, other functions may be more distantly related, with Celsr working only with one or a subset of the classical PCP partners. Here, we review the literature on Celsr in PCP and neural devel- opment, point to several remaining questions, and consider future challenges and possible research trends. Celsr1–3 genes encode atypical cadherins of more than 3000 amino acids ( Fig. 7.1). Their large ectodomain is composed of nine N-terminal cadherin repeats (typical cadherins have five repeats), six epidermal growth factor (EGF)-like domains, two laminin G repeats, one hormone receptor motif (HRM), and a G-protein-coupled receptor proteolytic site (GPS). -
