FSTL1 is a molecule with tremendous potential. While already considered an important clinical biomarker and cardioprotective cardiokine (a molecule secreted by cardiac muscle), Recchia et al demonstrate that FSTL1 also serves as a regulator of energy substrate metabolism. Using a canine tachy-pacing HF model, infusion of recombinant human FSTL1 exhibited efficacy in reversing pathological cardiac metabolism and remodelling.
