Pharmacological or genetic inhibition of Scn9a protects human and mouse beta cells while dampening insulin secretion in type 1 diabetes

P. Overby, A. G. Gordon, X.-Q. Dai, N. S. Nahirney, S. Provenzano, W. G. Sun, Y. Xia, J. A. Zhang, E. Panzhinskiy, C. M. J. Chu, H. H. Cen, S. Skovso, J. Kolic, A. G. Edwards, P. E. Macdonald, J. D. Johnson

This study shows that inhibiting Scn9a protects beta cells in type 1 diabetes by reducing excitability and improving survival, while also dampening insulin secretion.

Deletion of carboxypeptidase E in beta cells disrupts proinsulin processing and alters beta cell identity in mice

Y.-C. Chen, A. J. Taylor, J. M. Fulcher, A. C. Swensen, X.-Q. Dai, M. Komba, K. L. C. Wrightson, K. Fok, A. E. Patterson, R. I. Klein-Geltink, P. E. MacDonald, W.-J. Qian, C. B. Verchere

This study shows that deleting CPE in beta cells disrupts proinsulin processing and alters beta cell identity, leading to impaired function and increased beta-cell area in mice.

β-cell responses to high fat feeding: A role and mechanism for redox sensing by SENP1

H. Lin, K. Suzuki, N. Smith, X. Li, L. Nalbach, S. Fuentes, A. F. Spigelman, X.-Q. Dai, A. Bautista, M. Ferdaoussi, S. Aggarwal, A. R. Pepper, L. P. Roma, E. Ampofo, W.-h. Li, P. E. MacDonald

This study identifies SENP1's role in β-cell redox sensing during high-fat feeding, showing its requirement for enhanced exocytosis and glucose intolerance.

Beta-cell specific Insr deletion promotes insulin hypersecretion and improves glucose tolerance prior to global insulin resistance

S. Skovso, E. Panzhinskiy, J. Kolic, H. H. Cen, D. A. Dionne, X.-Q. Dai, R. B. Sharma, L. Elghazi, C. E. Ellis, K. Faulkner, S. A. M. Marcil, P. Overby, N. Noursadeghi, D. Hutchinson, X. Hu, , J. D. Johnson

This study shows that deleting the insulin receptor in beta-cells improves glucose tolerance in some mice but not others, depending on age and diet.
