The isoforms of pyruvate kinase act as nutrient sensors for the β-cell KATP channel

H. R. Foster, T. Ho, E. Potapenko, S. M. Sdao, S. L. Lewandowski, H. R. VanDeusen, S. M. Davidson, R. L. Cardone, M. Prentki, R. G. Kibbey, M. J. Merrins

This study identifies PKm1 and PKm2 as nutrient sensors that regulate β-cell KATP channels through mitochondrial PEP, influencing insulin secretion and Ca2+ oscillations.

Pyruvate kinase controls signal strength in the insulin secretory pathway

S. L. Lewandowski, R. L. Cardone, H. R. Foster, T. Ho, E. Potapenko, C. Poudel, H. R. VanDeusen, T. C. Alves, X. Zhao, M. E. Capozzi, I. Jahan, C. S. Nunemaker, J. E. Campbell, C. J. Thomas, R. G. Kibbey, M. J. Merrins

This paper shows pyruvate kinase (PK) controls insulin secretion by regulating ATP/ADP ratios and mitochondrial metabolism in beta-cells, suggesting PK activation as a potential diabetes therapy.
