ATGL-dependent white adipose tissue lipolysis controls hepatocyte PPARα activity

A. Fougerat, G. Schoiswohl, A. Polizzi, M. Regnier, C. Wagner, S. Smati, T. Fougeray, Y. Lippi, F. Lasserre, V. Melin, B. Tramunt, C. Alkhoury, A. Emile, M. Schupp, P. Gourdy, , H. Guillou

This study shows that adipose tissue lipolysis via ATGL regulates hepatocyte PPARα activity, which is essential for ketone body production, FGF21 secretion, and BAT activation during fasting and cold exposure.

Nuclear HMGB1 protects from non-alcoholic fatty liver diseases through negative regulation of liver X receptor

J. Personnaz, E. Piccolo, A. Dortignac, J. S. Iacovoni, J. Mariette, A. Polizzi, A. Batut, S. Deleruyelle, R. Paccoud, E. Moreau, F. Martins, T. Clouaire, F. Benhamed, A. Montagner, W. A. Wahli, , J.-P. Pradere

This study shows that nuclear HMGB1 suppresses liver lipogenesis in NAFLD by inhibiting LXR activity, preventing steatosis and insulin resistance.
