The anti-senescence effect of D-β-hydroxybutyrate in Hutchinson-Gilford progeria syndrome involves progerin clearance by the activation of the AMPK-mTOR-autophagy pathway.

D-β-hydroxybutyrate, BHB, has been previously proposed as an anti-senescent agent in vitro and in vivo in several tissues including vascular smooth muscle. Moreover, BHB derivatives as ketone esters alleviate heart failure. Here, we provide evidence of the potential therapeutic effect of BHB on Hutchinson-Gilford progeria syndrome (HGPS), a rare condition characterized by premature aging and heart failure, caused by the presence of progerin, the aberrant protein derived from LMNA/C gene c.
