    • Dysregulation of Glucagon Secretion by Hyperglycemia-Induced Sodium-Dependent Reduction of ATP Production 

      Knudsen, Jakob G; Hamilton, Alexander; Ramracheya, Reshma; Tarasov, Andrei I; Brereton, Melissa; Haythorne, Elizabeth; Chibalina, Margarita V; Spégel, Peter; Mulder, Hindrik; Zhang, Quan; Ashcroft, Frances M; Adam, Julie; Rorsman, Patrik (2019-02-05)
      Diabetes is a bihormonal disorder resulting from combined insulin and glucagon secretion defects. Mice lacking fumarase (Fh1) in their β cells (Fh1βKO mice) develop progressive hyperglycemia and dysregulated glucagon ...

    • Glucose stimulates somatostatin secretion in pancreatic δ-cells by cAMP-dependent intracellular Ca2+ release 

      Denwood, Geoffrey; Tarasov, Andrei; Salehi, Albert; Vergari, Elisa; Ramracheya, Reshma; Takahashi, Harumi; Nikolaev, Viacheslav O; Seino, Susumo; Gribble, Fiona; Reimann, Frank; Rorsman, Patrik; Zhang, Quan (2019-09-02)
      Somatostatin secretion from pancreatic islet δ-cells is stimulated by elevated glucose levels, but the underlying mechanisms have only partially been elucidated. Here we show that glucose-induced somatostatin secretion ...

    • Insulin inhibits glucagon release by SGLT2-induced stimulation of somatostatin secretion 

      Vergari, Elisa; Knudsen, Jakob G; Ramracheya, Reshma; Salehi, Albert; Zhang, Quan; Adam, Julie; Asterholm, Ingrid Wernstedt; Benrick, Anna; Briant, Linford J B; Chibalina, Margarita V; Gribble, Fiona M; Hamilton, Alexander; Hastoy, Benoit; Reimann, Frank; Rorsman, Nils J G; Spiliotis, Ioannis I; Tarasov, Andrei; Wu, Yanling; Ashcroft, Frances M; Rorsman, Patrik (2019-01-11)
      Hypoglycaemia (low plasma glucose) is a serious and potentially fatal complication of insulin-treated diabetes. In healthy individuals, hypoglycaemia triggers glucagon secretion, which restores normal plasma glucose levels ...
