Remedi and colleagues offer insight to insulin secretion disruption associated with KATP loss

On February 10, Maria S. Remedi, PhD and colleagues had their abstract titled “Hyperexcitability reduces TRPM5 in pancreatic β-cells: Insights into disruption of insulin secretion in chronically stimulated islets,” published in Biophysical Journal.  “Acute inhibition of ATP-sensitive K+ (KATP) channels in pancreatic β-cells result in depolarization, Ca2+ influx, and insulin secretion.” Throughout their research, the […]

Protein palmitoylation helps to model the evolution of some forms of type 2 diabetes   

On February 7, Guifang Dong, PhD; Sangeeta Adak, PhD; Qiang Zhang, PhD; Chu Feng, MS; Li Yin, MD; Sarah Speck; Shuntaro Morikawa; Rie Asada, PhD; Fumihiko Urano, MD, PhD; Maria Remedi, PhD; Xiaochao Wei, PhD; Clay Semenkovich, MD; and collaborators had their work published in “Cell Metabolism.”  “Hyperinsulinemia often precedes type 2 diabetes,” and palmitoylation, […]

Semenkovich Lab and collaborators show the evolution of type 2 diabetes through APT1 deficiency 

On January 11, Semenkovich Lab and collaborators, had their research titled “Palmitoylation couples insulin hypersecretion with β cell failure in diabetes,” published in “Cell Metabolism.”  Hyperinsulinemia is known to often come before type 2 diabetes. In the study, they explain how acyl-protein thioesterase 1 (APT1) knockdown in nondiabetic islets causes insulin hypersecretion.  By using palmitoylation proteomics, their […]

Remedi publishes on ATP-sensitive potassium channels in hyperinsulinism and type 2 diabetes

On February 23, Maria S. Remedi, PhD and collaborators had their findings published in “Diabetes,” titled “ATP-Sensitive Potassium Channels in Hyperinsulinism and Type 2 Diabetes: Inconvenient Paradox or New Paradigm?” The article is meant to assess if adenosine triphosphate-sensitive potassium (KATP) channels are a new and effective way of thinking, in regard to hyperinsulinism and type […]
