Interference between PARPs and SIRT1: a novel approach to healthy ageing?

Johan Auwerx, Carlos Canto Alvarez

Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...

Engineered aprotinin for improved stability of fibrin biomaterials

Jeffrey Alan Hubbell, Peter Frey

Fibrin has been long used clinically for hemostasis and sealing, yet extension of use in other applications has been limited due to its relatively rapid resorption in vivo, even with addition of aprotinin or other protease inhibitors. We report an engineer ...

SRT1720 improves survival and healthspan of obese mice

Johan Auwerx, Carlos Canto Alvarez

Sirt1 is an NAD1-dependent deacetylase that extends lifespan in lower organisms and improves metabolism and delays the onset of age-related diseases in mammals. Here we show that SRT1720, a synthetic compound that was identified for its ability to activate ...

The Pro12Ala PPARgamma2 variant determines metabolism at the gene-environment interface

Johan Auwerx

The metabolic impact of the common peroxisome proliferator-activated receptor gamma isoform 2 (PPARgamma2) variant Pro12Ala in human populations has been widely debated. We demonstrate, using a Pro12Ala knockin model, that on chow diet, Ala/Ala mice are le ...
