Pantothenate Kinase 4 controls efficient skeletal muscle energy substrate metabolism via acetyl-CoA

A. Miranda-Cervantes, A. M. Fritzen, S. H. Raun, O. Hodek, L. L. V. Moller, K. Johann, L. Deisen, P. Gregorevic, A. Gudiksen, A. Artati, J. Adamski, N. R. Andersen, P. Schjerling, A. Cebrian-Serrano, M. Jaehnert, , M. Kleinert

This study identifies PanK4 as a regulator of skeletal muscle energy metabolism, showing its role in acetyl-CoA regulation and metabolic flexibility.

The GDF15-GFRAL pathway is dispensable for the effects of metformin on energy balance

A. B. Klein, T. S. Nicolaisen, K. Johann, A. M. Fritzen, C. V. Mathiesen, C. Gil, N. S. Pilmark, K. Karstoft, M. B. Blond, J. S. Quist, R. J. Seeley, K. Faerch, J. Lund, M. Kleinert, C. Clemmensen

This study shows metformin increases GDF15 but does not rely on the GDF15-GFRAL pathway for its weight-lowering effects in mice.

Pharmacological but not physiological GDF15 suppresses feeding and the motivation to exercise

A. B. Klein, T. S. Nicolaisen, N. Ortenblad, K. D. Gejl, R. Jensen, A. M. Fritzen, E. L. Larsen, K. Karstoft, H. E. Poulsen, T. Morville, R. E. Sahl, J. W. Helge, J. Lund, S. Falk, M. Lyngbaek, , C. Clemmensen

The paper shows that exercise increases circulating GDF15 levels, but this physiological increase does not suppress appetite or exercise motivation like pharmacological GDF15.

X. Han, S. Raun, M. Carlsson, K. A. Sjoberg, C. Henriquez-Olguin, M. Ali, A. Lundsgaard, A. M. Fritzen, L. L. V. Moller, Z. Li, J. Li, T. E. Jensen, B. Kiens, L. Sylow

This study shows cancer reduces insulin-stimulated glucose uptake in muscle and adipose tissue and impairs muscle microvascular perfusion in mice.
